10 Report on Proposals June 2013 NFPA Log #1033 NEC-P11 Final Action: Accept in Principle in Part (430, Parts I through X) Submitter: James T. Dollard, Jr., IBEW Local Union 98 Recommendation: Replace 600V with 1000V. Substantiation: This proposal is the work of the High Voltage Task Group appointed by the Technical Correlating Committee. The task group consisted of the following members: Alan Peterson, Paul Barnhart, Lanny Floyd, Alan Manche, Donny Cook, Vince Saporita, Roger McDaniel, Stan Folz, Eddie Guidry, Tom Adams, Jim Rogers and Jim Dollard. The Task Group identified the demand for increasing voltage levels used in wind generation and photovoltaic systems as an area for consideration to enhance existing NEC requirements to address these new common voltage levels. The task group recognized that general requirements in Chapters 1 through 4 need to be modified before identifying and generating proposals to articles such as 690 specific for PV systems. These systems have moved above 600V and are reaching 1000V due to standard configurations and increases in efficiency and performance. The committee reviewed Chapters 1 through 8 and identified areas where the task group agreed that the increase in voltage was of minimal or no impact to the system installation. Additionally, there were requirements that would have had a serious impact and the task group chose not to submit a proposal for changing the voltage. See table (supporting material) that summarizes all sections considered by the TG. Note: Supporting material is available for review at NFPA Headquarters. Panel Meeting Action: Accept in Principle in Part. Panel Statement: The panel concludes that Article 430 needs to be reviewed and modified and is requesting input regarding proper spacing at the comment phase. The panel accepts changing 600v to 1000v everywhere in Article 430 except in the tables in where the panel concludes that additional changes need to be investigated. The panel has appointed a task group to review this issue and report back at the ROC and to submit any necessary comments.

13 Page 1 of 1 11/20/2014 Public Input No NFPA [ Global Input ] Change "physical damage" to "mechanical damage" The term "physical damage" is often a source of confusion. One of the points of confusion is what is included in "physical damage"; for example, is exposure to corrosive gas included? I believe other language in the code covers that type of situation, and "mechanical damage" more clearly reflects the intent of the requirements in the NEC that currently refer to "physical damage".

17 Page 1 of 2 Public Input No NFPA [ Global Input ] Change the use of the phrase "60 V DC" to "Nominal 50V DC" throughout the NFPA 70 Standard. The NEC is conflicted in its use of the terminology which defines the DC voltage level on when certain code rules apply. It would appear that half of the NEC code sections refer to 60V dc as the voltage limit which mandates certain code requirements. And it would appear the other half refers to "50V DC". The code should be consistent in its approach. This public input seeks to resolve this conflict and come up with consistent terminology throughout the code. In (A)(1)(b) working space requirements are for 60V DC refers to 60V DC for grounding requirements for DC systems refers to listing requirements for certain DC equipment at 60V (D) refers to elevator requirements for uninsulated parts at no more than 60V DC. Article 640 and 647 have similar DC voltage limits. For the 50 volt level guarding of live parts in refers to both AC and DC systems refers to marking of conductors at 50 volts or less regardless of voltage type. Article 720 refers to systems at 50 volts or less whether DC or AC (C)(2) refers to marking of conductors for DC systems 50V or less (C)(2) refers to identification of DC feeder conductors at 50V or less. Section states that overcurrent protection shall not be required for conductors from a battery with a nominal voltage of 50 volts or less refers to DC storage batteries that operate at a voltage of 50 volts, nominal or less. There are many other codes sections not mentioned which vary back and forth between 50 and 60V. The code is not consistent. I am recommending that globally the term 60V DC be replaced with 50V nominal DC. Submitter Full Name: Lawrence Ayer Organization: Biz Com Electric, Inc.

18 Page 1 of 2 Public Input No NFPA [ Global Input ] Move all definitions to Article 100. It seems that every cycle definitions are moved from a.2 section within an Article to Article 100 because someone points out that the particular term is used in more than one Article. For NEC users, especially new ones it makes understanding the rules that much more difficult. We also have examples like Dustight that is defined differently in Article 100 as compared to That creates confusion. A greater problem is when a term is defined within an Article yet the term is used elsewhere in the NEC. Is the term in the Article without it being defined supposed to be something different or can it be used the same way? That also creates confusion. Some examples include Metal wireway which is defined in yet the term is used elsewhere such as in Articles 210, 225, etc. A Tap conductor is defined in 240.2, is a motor tap conductor supposed to be something different in Article 430? As stated in the NEC Style Manual definitions cannot contain requirements yet it is often argued that stating that something is or is not does not necessarily constitute a requirement. If it is not, then it doesn't meet the definition. If the term is used in multiple articles then creating a definition that is usable in all those Articles is the best approach. Specific requirements which can be different can still be placed in each Article Many other standards have all definitions in one location. Constancy will be improved by having the panels develop language that will use the same terms without creating unnecessary conflicts. I understand the Correlating Committee recently agreed to leave terms in the.2 Section of Articles. I respectfully ask them to reconsider that position.

20 Page 2 of 14 Globally edit the text by removing the following text strings nominal Nominal, nominal, Nominal nominal, Nominal,, nominal,, Nominal, That is, remove the word nominal and any optional commas preceding or following it. This is a little too broad, I will provide additional submissions that repair "collateral damage" to nominals not related to voltage. Substantiation: The NEC contains 2744 sentences that contain volt, voltage, and V. Some of the V are false positives (part V, Volume...). 317 sentences contain nominal. The use of the word nominal does not appear to have a particular pattern when it is found in connection to voltage. Having some voltages marked as nominal and others not marked when both are intended to be nominal, leads to confusion Making it clear what a particular voltage reference meains is important. Some of the voltage references are for exact voltages. This is true for most "limit" specifications such as "the voltage shall not exceed 42.4 volts". Other voltages are nominal and refer to a range of voltages. The specification of 600 volts, which is a utilization voltage, and 1000 volts, which is the "new" 600 volts, is problematical. I have chosen to treat these references as nominal. I propose that the NEC indicate that all voltages listed in it are nominal, unless specifically marked actual This would rid the document of uncertainty as to whether or not a given voltage specification was actual or nominal. Also add a table that indicates that the three groups of nominal voltages refer to the same thing: for instance 125/250 device rating, 120/240 load rating, and 115/230 motor rating. Coordination: These changes need to be co-ordinated with other submissions These submission will be keyed back to this submission number (1902).

29 136 of /18/2014 2:46 PM Public Input No NFPA [ Section No ] Grounding Bonding. Multisection industrial control panels shall be bonded together with an equipment grounding bonding conductor or an equivalent equipment grounding bonding bus sized in accordance with Table Equipment grounding bonding conductors shall be connected to this equipment grounding bonding bus or to an equipment grounding bonding termination point provided in a single-section industrial control panel. The term equipment grounding conductor is a misnomer even though it has been in use for many many years. Although it is a grounded conductor in normal practice for grounded systems, the idea that grounding makes a system safe and prevents an electrical shock is inherently false. Connecting a conductor from metallic equipment likely to become energized to the earth does not reduce the shock potential during a fault but, rather, may enhance it if it becomes the only path back to the source. The shock potential is the voltage drop along the conductor (equipment grounding conductor) due to fault current flowing back to the source. The shock hazard depends upon the time until the fault is cleared by an overcurrent device or some other event, thus the clearing time is a critical factor in safety. This conductor (equipment grounding conductor) is intended to protect equipment and personnel by providing a sufficiently high fault current to operate an overcurrent device and clear the fault rapidly. A low impedance fault current path can provide the necessary high fault current regardless of whether the conductor is grounded or not. It is only the fault current path and not the grounding that can provide the high fault current necessary to operate an overcurrent device rapidly. The term bonding is generally used to insure that a connection and current path is low impedance, reliable, and able to withstand the fault current. This conductor provides a basic bonding function by insuring, through proper sizing and bonding jumpers as necessary, that the connection from equipment to fault current source is both low impedance and reliable. A bonding function is the necessary function rather than a grounding function to clear a fault rapidly. A grounding function is provided by a grounding electrode conductor that connects an electrical system source to the earth. An overcurrent device operates in a time interval based upon the current through it. That current depends upon proper bonding to the source and is relatively independent of connection to the grounding electrode at the source where the overcurrent device is located. The use of the term equipment bonding conductor would better describe the function of this important conductor instead of the term equipment grounding conductor. Systems are grounded, equipment is bonded. Making this change would also bring the NEC into conformity with the Canadian Electrical Code which uses the term equipment bonding conductor. Code Panel 5 members have often stated that those in the industry understand what the purpose of the equipment grounding conductor is for. The Panel members understand this also. There are, however, many people doing electrical work who don t understand and think connecting equipment to a local grounding electrode accomplishes the same objective as an equipment grounding conductor. This is apparent from the large number of questions that are asked at IAEI inspectors meetings, grounding classes, and as documented recently in the July/August 2014 issue of the NFPA Journal under the title Pool Rules. Just ask the inspectors and the teachers. Changing the terminology will serve to make it clear that the principal function of this conductor is to bond the equipment being protected to the source where the fault current originates. Changing the terminology will not confuse those that understand the proper purpose of this bonding conductor.

(5) An enclosure type number shall be marked on the industrial control panel enclosure. This proposed change will address a gap in worker safety while providing relief to industrial facilities. The current wording warns a service technician that multiple sources of power are present, but provides no guidance in how to locate those sources of power. If an emergency arises which necessitates disconnection of power but the technician is unfamiliar with the facility there could be a risk to both personnel and property. The proposed change will require that generally all industrial control panels be marked with the locations of all sources of power. This is a common concept that has been adopted in several places throughout the NEC in recent cycles, such as (F) to identify sources of power for feeder or branch-circuits passing through another building or structure, 312.8(3) requiring identification of disconnecting means for panelboard enclosures containing feed-through conductors, 408.4(B) for the source of power to the panelboard or switchgear, (B) for transformers, etc. These requirements all enhanced worker safety, as will the proposed change. The proposed exception is intended to address installations where due to the number of sources of power located in a particular industrial control panel a single label or placard identifying all sources would be unpractical, if not impossible. Some situations could result in labels larger than the industrial control panel, or, if sized to fit the panel, would result in a font size so small that it would be unreadable. Since these are locations under engineering supervision and only qualified persons will service the installation, having the required documentation in a readily

33 141 of /18/2014 2:46 PM accessible location for those individuals would still provide an acceptable level of protection. The label on the panel would only be required to indicate where this documentation is located. Additionally, this will not require the label to be constantly updated as circuits are added or removed, only that the engineering drawings and documentation be kept up to date. This will provide an acceptable balance between enhancing the safety of workers engaged in maintenance activities and avoiding creating burdensome labeling requirements for facilities.

34 133 of /18/2014 2:46 PM Public Input No. 630-NFPA [ Section No ] Short-Circuit Current Rating. An industrial control panel shall not be installed where the available fault current exceeds its short-circuit current rating as marked in accordance with (4). Where the available fault current is not known the industrial control panel shall be protected by an overcurrent device that will limit the fault current to a value that will be equal to or less than the marked short-circuit current rating of the industrial control panel. Many industrial control panels have an SCCR marking, but the available fault current is not marked on the distribution equipment. This makes it very difficult for installers to comply with the first statement of this section. The available fault current value is currently required to be on the service equipment only. The addtional language is to make the installer aware that a means of limiting the fault current should be installed to protect the industrial control panel. That means would be some type of device with current limiting characteristics. Submitter Full Name: WILLIAM GROSS Organization: Tri-City Electric Submittal Date: Thu May 29 13:42:48 EDT 2014

Type CM communications cables shall be listed as being suitable for general-purpose communications use, with the exception of risers and plenums, and shall also be listed as being resistant to the spread of fire. Informational Note 1 : One method of defining resistant to the spread of fire is that the cables do not spread fire to the top of the tray in the UL Flame Exposure, Vertical Flame Tray Test in ANSI/UL , Standard for Safety for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables. The smoke measurements in the test method are not applicable. Another method of defining resistant to the spread of fire is for the damage (char length) not to exceed 1.5 m (4 ft 11 in.) when performing the CSA Vertical Flame Test Cables in Cable Trays, as described in CSA C22.2 No. 0.3-M-2001, Test Methods for Electrical Wires and Cables. Informational Note 2 : One method of defining optional limited smoke characteristics for generalpurpose use cables is that the cables exhibit a peak smoke release rate not exceeding 0.25 m2/s and a total smoke released not exceeding 95 m2 when tested in accordance with the "UL Flame Exposure, Vertical Tray Flame Test" in ANSI/UL , Standard for Safety for Vertical-Tray F-re-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables"CSA "Vertical Flame Test - Cables in Cable Trays. Another method of defining optional limited smoke characteristics for general-purpose use cables is that the cables exhibit a peak smoke release rate not exceeding 0.40 m2/s and a total smoke released not exceeding 150 m2 when tested in accordance with the CSA "Vertical Flame Test - Cables in Cable Trays," as described in CSA C22.2 No. 0.3-M-2009, Test Methods for Wires and Cables". The UL 1685 and the CSA FT4 standard both include ways in which a marking of limited smoke can be obtained, but the code is silent about it. It would be helpful for users who are interested in obtaining a limited smoke cable to be able to avail themselves of this option specifically. It is well known that the lack of visibility in fires is a critical component of fire safety. This proposed change will not require such a marking but will indicate its optional existence.

Informational Note: For additional information see IEEE Recommended Practice for the Lighting of Industrial and Commercial Facilities Illumination technology has been a fast-moving space in recent years due to energy conservation concerns so a stronger linkage with accepted engineering practice is necessary for all stakeholders. The IEEE Industrial Applications Society 3000 series of standards are part of a larger project to revise and reorganize the technical content of the 13 existing IEEE Color Books which provided significant engineering information from experienced engineers. The Red, White, and Gray Color books, for example, contained information about illumination technology but was not previously referenced into this section. It is time to do this now. While many of the 3000 series standards are still works in progress and the topical coverage seeking its proper place it is not too soon for the various NEC committees to evaluate the importance of strengthening the NEC s linkage to the best engineering information possible. The benefit of now referencing the 3000 series of documents into the NEC now include, but are not limited to: 1) the elimination of duplicate material that now exists in the various color books, 2) the speeding up of the revision process by allowing Color Book content to be reviewed, edited and balloted in smaller segments, and 3) to accommodate more modern, efficient and cost effective physical publishing/distribution methodologies (i.e., the elimination of large and expensive to produce books). This recommended practice is likely to be of greatest value to the power-oriented engineer with limited experience with such requirements and a way to connect more directly with domain expertise in leading practice for designing and installing safe supply circuits for illumination technology.

58 308 of /18/2014 2:46 PM Public Input No NFPA [ Section No (A) ] (A) Material. Where motors are provided with terminal housings, the housings shall be of metal and of substantial construction. Exception: In other than hazardous (classified) locations, substantial, nonmetallic, noncombustible housings shall be permitted, provided an internal grounding bonding means between the motor frame and the equipment grounding bonding connection is incorporated within the housing. The term equipment grounding conductor is a misnomer even though it has been in use for many many years. Although it is a grounded conductor in normal practice for grounded systems, the idea that grounding makes a system safe and prevents an electrical shock is inherently false. Connecting a conductor from metallic equipment likely to become energized to the earth does not reduce the shock potential during a fault but, rather, may enhance it if it becomes the only path back to the source. The shock potential is the voltage drop along the conductor (equipment grounding conductor) due to fault current flowing back to the source. The shock hazard depends upon the time until the fault is cleared by an overcurrent device or some other event, thus the clearing time is a critical factor in safety. This conductor (equipment grounding conductor) is intended to protect equipment and personnel by providing a sufficiently high fault current to operate an overcurrent device and clear the fault rapidly. A low impedance fault current path can provide the necessary high fault current regardless of whether the conductor is grounded or not. It is only the fault current path and not the grounding that can provide the high fault current necessary to operate an overcurrent device rapidly. The term bonding is generally used to insure that a connection and current path is low impedance, reliable, and able to withstand the fault current. This conductor provides a basic bonding function by insuring, through proper sizing and bonding jumpers as necessary, that the connection from equipment to fault current source is both low impedance and reliable. A bonding function is the necessary function rather than a grounding function to clear a fault rapidly. A grounding function is provided by a grounding electrode conductor that connects an electrical system source to the earth. An overcurrent device operates in a time interval based upon the current through it. That current depends upon proper bonding to the source and is relatively independent of connection to the grounding electrode at the source where the overcurrent device is located. The use of the term equipment bonding conductor would better describe the function of this important conductor instead of the term equipment grounding conductor. Systems are grounded, equipment is bonded. Making this change would also bring the NEC into conformity with the Canadian Electrical Code which uses the term equipment bonding conductor. Code Panel 5 members have often stated that those in the industry understand what the purpose of the equipment grounding conductor is for. The Panel members understand this also. There are, however, many people doing electrical work who don t understand and think connecting equipment to a local grounding electrode accomplishes the same objective as an equipment grounding conductor. This is apparent from the large number of questions that are asked at IAEI inspectors meetings, grounding classes, and as documented recently in the July/August 2014 issue of the NFPA Journal under the title Pool Rules. Just ask the inspectors and the teachers. Changing the terminology will serve to make it clear that the principal function of this conductor is to bond the equipment being protected to the source where the fault current originates. Changing the terminology will not confuse those that understand the proper purpose of this bonding conductor.

79 326 of /18/2014 2:46 PM Public Input No NFPA [ Sections , ] Sections , Service Equipment. Where used as service equipment, each motor control center shall be provided with a single main disconnecting means to disconnect all ungrounded service conductors. Exception: A second service disconnect shall be permitted to supply additional equipment. Where a grounded conductor is provided, the motor control center shall be provided with a main bonding jumper, sized in accordance with (D), within one of the sections for connecting the grounded conductor, on its supply side, to the motor control center equipment ground bond bus. Exception: High-impedance grounded neutral systems shall be permitted to be connected as provided in Grounding Bonding. Multisection motor control centers shall be connected together with an equipment grounding bonding conductor or an equivalent equipment grounding bonding bus sized in accordance with Table Equipment grounding bonding conductors shall be connected to this equipment grounding bonding bus or to a grounding bonding termination point provided in a single-section motor control center. The term equipment grounding conductor is a misnomer even though it has been in use for many many years. Although it is a grounded conductor in normal practice for grounded systems, the idea that grounding makes a system safe and prevents an electrical shock is inherently false. Connecting a conductor from metallic equipment likely to become energized to the earth does not reduce the shock potential during a fault but, rather, may enhance it if it becomes the only path back to the source. The shock potential is the voltage drop along the conductor (equipment grounding conductor) due to fault current flowing back to the source. The shock hazard depends upon the time until the fault is cleared by an overcurrent device or some other event, thus the clearing time is a critical factor in safety. This conductor (equipment grounding conductor) is intended to protect equipment and personnel by providing a sufficiently high fault current to operate an overcurrent device and clear the fault rapidly. A low impedance fault current path can provide the necessary high fault current regardless of whether the conductor is grounded or not. It is only the fault current path and not the grounding that can provide the high fault current necessary to operate an overcurrent device rapidly. The term bonding is generally used to insure that a connection and current path is low impedance, reliable, and able to withstand the fault current. This conductor provides a basic bonding function by insuring, through proper sizing and bonding jumpers as necessary, that the connection from equipment to fault current source is both low impedance and reliable. A bonding function is the necessary function rather than a grounding function to clear a fault rapidly. A grounding function is provided by a grounding electrode conductor that connects an electrical system source to the earth. An overcurrent device operates in a time interval based upon the current through it. That current depends upon proper bonding to the source and is relatively independent of connection to the grounding electrode at the source where the overcurrent device is located. The use of the term equipment bonding conductor would better describe the function of this important conductor instead of the term equipment grounding conductor. Systems are grounded, equipment is bonded. Making this change would also bring the NEC into conformity with the Canadian Electrical Code which uses the term equipment bonding conductor. Code Panel 5 members have often stated that those in the industry understand what the purpose of the equipment grounding conductor is for. The Panel members understand this also. There are, however, many people doing electrical work who don t understand and think connecting equipment to a local grounding electrode accomplishes the same objective as an equipment grounding conductor. This is apparent from the large number of questions that are asked at IAEI inspectors meetings, grounding classes, and as documented recently in the July/August 2014 issue of the NFPA Journal under the title Pool Rules. Just ask the inspectors and the teachers. Changing the terminology will serve to make it clear that the principal function of this conductor is to bond the equipment being protected to the source where the fault current originates. Changing the terminology will not confuse those that understand the proper purpose of this bonding conductor. Submitter Full Name: ELLIOT RAPPAPORT Organization: ELECTRO TECHNOLOGY

AREA IN FRONT OF ELECTRICAL EQUIPMENT SHALL BE KEPT CLEAR FOR- DEPTH_- WIDTH- HEIGHT. The marking shall also include the dimensions of the depth, width, and height required to be kept clear for the work space. It shall be permitted to use one sign for multiple pieces of equipment as long as the sign is visible from the work space for each piece of equipment I am continually being forced to work on panelboards, switchboards and motor control centers that were originally installed with plenty of work space, but over time have had the work space encroached upon by other trades or unknowing individuals who install shelves, pipes, ductwork, walls, and all kinds of other obstructions too close to the electrical equipment. This places me and every other electrical worker in peril if I need to work on the equipment while energized. There is a great increase in danger from an arc-flash injury or a shock when working on an energized motor control center if the work space has been compromised. I have surveyed HUNDREDS of students that attend my classes and seminars and they all agree that they have also been put into this dangerous situation. Members of the Code Making Panel themselves may have worked in these situations. This is NOT just an enforcement issue, but also a rather immediately DANGEROUS situation if the equipment is unreachable in an emergency, such as firefighters, or other emergency personnel (or anyone else for that matter) needing to turn the power off because of an emergency!!!!! They certainly cannot wait for the wire inspector to show up and enforce the code. It will be too late by that time. But maybe, just maybe the plumber won t put the pipe in the way, or the carpenter won t build the wall too close, or the shop owner won t install shelves right in front of the MCC if there were a sign to warn them! It s certainly not a guarantee, but if the warning sign were to prevent ONE tragedy, then making this a requirement will certainly be worth it. These signs are already available for just a few dollars. Well worth the minimal cost. The wording in my proposal also allows for the sign to be placed on a wall or perhaps on the door to the electrical room, as long as the sign is clearly visible to anyone standing in the workspace thinking of putting an obstruction in front of the electrical panel. I believe a warning sign WOULD help. Just as an Arc-Flash warning sign is INTENDED to help, but does not guarantee the electrician will heed the warning. Signs, markings, and plaques are required in several sections of the Code such as , (C), (C), 210.5(C)(3), (C), , (A)(1), 230.2(E), (C), , , 450.8(D), , (B)(2), , (A)(8), (B)(3), (A)(7), (G), 690.7(E)(3), (D)(4), (E)(3), (A), (B), 692.4(B), 692.9(C), 700.7(B), 701.7(B), 702.7(B), and None of these signs guarantee safety, they can only help improve it. If you check each of those sections, I think you will agree that the sign or plaque that I am proposing is at least equal in importance to any of the other signs required by Code and perhaps MORE important than others.

Substantiation; The general requirement for controllers per is to have a disconnect ahead of all controllers for the ability to service the controller with no shock hazard present. NEC offers the allowance to have the required disconnect inside the controller. This relaxation of the code is often taken advantage of especially with many controllers having a factory integral disconnect. The consequence is that there is no guide or restrictions as to where the circuit(s) can enter the controller which often finds the wiring on the line side of the disconnect hidden in a plastic cable tray (panduit) with other control wiring, thus giving technicians a false sense of security after the disconnect has been opened. In 2014 NEC 600.6(A)(1)CMP 16 took safeguarding steps in requiring that a disconnect for a sign shall be at the point of entry where the circuits enter. To mirror this change would be prudent. Controllers are often commissioned while energized but also serviced while de-energized such as checking for continuity and installing replacement parts. From my experience as a inspector for 14 years and a commercial installer for over 10 this requirement would not be a unnecessary hardship of any kind to the installer.

This informative annex provides application information for ampacities calculated under engineering supervision Section (D) provides ampacity calculation information and conductor installation requirements for conductors installed underground. (2) Typical Applications Covered by Tables. Typical ampacities for conductors rated 0 through 2000 volts are shown in Table B (B)(2)(1) through Table B (B)(2)(10). Table B (B)(2)(11) provides the adjustment factors for more than three current-carrying conductors in a raceway or cable with load diversity. Underground electrical duct bank configurations, as detailed in Figure B (B)(2)(3), Figure B (B)(2)(4), and Figure B (B) (2)(5), are utilized for conductors rated 0 through 5000 volts. In Figure B (B)(2)(2) through Figure B (B)(2)(5), where adjacent duct banks are used, a separation of 1.5 m (5 ft) between the centerlines of the closest ducts in each bank or 1.2 m (4 ft) between the extremities of the concrete envelopes is sufficient to prevent derating of the conductors due to mutual heating. These ampacities were calculated as detailed in the basic ampacity paper, AIEE Paper , The Calculation of the Temperature Rise and Load Capability of Cable Systems, by J. H. Neher and M. H. McGrath. For additional information concerning the application of these ampacities, see IEEE/ICEA Standard S-135/P , Power Cable Ampacities, and IEEE Standard , Standard Power Cable Ampacity Tables. Typical values of thermal resistivity (Rho) are as follows: Average soil (90 percent of USA) = 90 Concrete = 55 Damp soil (coastal areas, high water table) = 60 Paper insulation = 550 Polyethylene (PE) = 450 Polyvinyl chloride (PVC) = 650 Rubber and rubber-like = 500 Very dry soil (rocky or sandy) = 120 Thermal resistivity, as used in this informative annex, refers to the heat transfer capability through a substance by conduction. It is the reciprocal of thermal conductivity and is normally expressed in the units Ccm/watt. For additional information on determining soil thermal resistivity (Rho), see ANSI/IEEE Standard , Guide for Soil Thermal Resistivity Measurements. (3) Criteria Modifications. Where values of load factor and Rho are known for a particular electrical duct bank installation and they are different from those shown in a specific table or figure, the ampacities shown in the table or figure can be modified by the application of factors derived from the use of Figure B (B)(2)(1). Where two different ampacities apply to adjacent portions of a circuit, the higher ampacity can be used beyond the point of transition, a distance equal to 3 m (10 ft) or 10 percent of the circuit length calculated at the higher ampacity, whichever is less. Where the burial depth of direct burial or electrical duct bank circuits are modified from the values shown in a figure or table, ampacities can be modified as shown in (a) and (b) as follows. (a) Where burial depths are increased in part(s) of an electrical duct run to avoid underground obstructions, no decrease in ampacity of the conductors is needed, provided the total length of parts of the duct run increased in depth to avoid obstructions is less than 25 percent of the total run length.

94 Substantiation: This Public Input seeks to modify Section (F) to support modified Sections (A) and (C) that provides requirements for the new technology. This is one of 3 linked Public Inputs: the second PI modifies Sections (A) and (C) to provide requirements for the new technology and a third PI creates a new associated definition for Attachment Fitting. Similar sets of Public Inputs were submitted in the event the Panel wished to consider two alternate locations for adding this new technology, including submitting the same concepts to Sections (B) as well as another set to insert a new There is a new third party certified combination that includes the use of a receptacle and an attachment fitting to supply, support and connect ceiling- or wall-luminaires and ceilingsuspended luminaires, and ceiling-suspended (paddle) fans. The attachment fitting is a recognized component used as part of a listed product. The attachment fitting is inserted in a listed receptacle. This Public Input is part of series of Public Inputs submitted to assure that this new third party certified combination is recognized by users and inspectors, and installed in a consistent and safe manner. There are 5 topics addressed in this substantiation: 1) Why new NEC text is needed; 2) explanation of the new technology; 3) what problem is being solved by adding new text; 4) relevant fatality and injury data; and 5) documentation that there are no essential patent concerns. Why new and modified NEC text is necessary. This multifunctional receptacle and attachment fitting (not plug) combination is a new technology category and is not intended to be product or manufacturer specific. It should be noted that the attachment fitting is not a plug since it is used as part of a listed utilization device (luminaire or paddle fan). The technology is a load-bearing receptacle that is a quick connect and disconnect method that allows for safe wiring, installation and removal for ceiling mounted luminaires and ceiling fans. Once the receptacle and cover plate are in place, since the luminaire is disconnected from the power source until plugged in and there are not exposed energized parts, installation and connection of the utilization equipment (luminaire or paddle fan) is inherently safe. By adding this text to address the new technology, it is easier for inspectors, installers and others to recognize, understand and assess this new technology and method of installation. Additionally for installers, it represents technology that eliminates or reduces electrical hazards in many common instances described in the Data portion of this substantiation. An example of this type of technology is the GE/Safety Quick Lighting and Fans Corp (SQL) product, of which over a million of these units were sold between 2007 and It is projected that availability and recognition of the technology will significantly increase usage. As the popularity of the technology grows, it is reasonable to assume other designs of the locking support and mounting receptacle and attachment fitting combination will arise. It is requested that the NEC Panels proactively recognize the new technology, as it will be in wide use and it will increase safety. Examples of new technology that have been acknowledged in the NEC past include wind turbines and electric vehicle charging systems in order to keep up with advances in the state-of-the-art electrical technologies. 1 P age

95 Ensuring Recognition of Appropriate NEC Requirements and Safe Installation. When the technology was submitted to UL to obtain a listing, it was initially placed in the New and Unusual category. As such, it was submitted to UL s Electrical Council, and after much review and discussion, the technology was determined to be a receptacle and fitting (not plug) combination, and was successfully listed to UL 498, Attachment Plugs and Receptacles. Considering UL s extensive steps used to categorize and evaluate the technology, it is foreseeable that others might not realize that this technology is indeed considered a receptacle and fitting (not plug) combination, nor understand the requirements for electrical safety unless the technology is clearly addressed in the NEC. This new technology combination of receptacle and attachment fitting cannot be electrically overloaded because an appropriate fitting will always be matched with the utilization device as part of its construction in accordance with its third party certification. Data from Consumer Products Safety Commission (CPSC), National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) show that the traditional methods of changing an existing luminaire or maintaining existing luminaires can be dangerous. This technology significantly reduces and in many cases eliminates these hazards. For these reasons, the technology should be addressed in the NEC. What is the technology? The technology is different than what is currently addressed in (A) and (C). The technology is a load-bearing receptacle that is a quick connect and disconnect method for ceiling mounted luminaires and ceiling fans. By adding this new section to address the new technology, the receptacle and attachment fitting combination, it allows inspectors to recognize what requirements govern the technology therefore they can easily understand and assess this new technology and method of installation. Although the suggested text is not intended to be product or manufacturer specific, an example of this technology from GE/SQL can be seen in the photo provided; a video describing the new technology can also be seen at With this new technology, the receptacle is installed to the ceiling outlet box, completing the wiring of the branch circuit through the receptacle unit. The electrician then installs a cover plate, just as with other receptacle types. To complete the installation, the luminaire or fan, by means of the attachment fitting that is part of the utilization equipment, is simply quick connected into the receptacle and the luminaire or ceiling fan installation is complete. What problem is being solved? By adding the new text, there is clear categorization of the new technology and the requirements to ensure electrical safety by electricians and inspectors. By adding this new section to address the new technology, it is safer and easier for installers, inspectors and others to recognize, understand and assess this new technology and method of installation to the appropriate requirements of the NEC. Intuitively we understand that not having to rewire each unit when the luminaire or ceiling fan is changed is safer, and there are data from CPSC, NIOSH and OSHA to confirm this notion. When an electrician installs the receptacle (female unit), it is mounted on a variation of the traditional crossbar. The attachment fitting (male fitting) is attached by the manufacturer to the luminaire, and is not available without attachment to a listed appliance. Thereby facilitating and increasing safety when the electrician installs the luminaire. Similar to the use of a ballast disconnect, this 2 P age

96 combination works to minimize or eliminate risk associated with electrical shock and associated injuries, especially when the use of ladders and support of devices are involved, or when the utilization device itself needs to be worked on. Relevant Fatality and Injury Data. OSHA Data. In the OSHA electrocution training materials, an OSHA Fatal Fact is presented 1 that details a union electrician s death by electrocution during trouble shooting with lamps. If the technology was used, the lamps could ve been disconnected and troubleshooting take place without the presence of electrical hazards. There is an OSHA Incident Report # Another OSHA Incident Report 3 # summarizes a 2008 electrocution of an electrician while changing a light bulb. It is reasonable to conclude that this incident could have been avoided if the new technology receptacle/attachment fitting technology had been used. The fixture would ve been disconnected and a new bulb would be inserted into the disconnected fixture with no access to electricity. In 2011, an electrician was electrocuted when the wires of a light fixture he was attempting to hang became stripped energizing the light fixture. As he grabbed one of the attached steel hanging cables, he received a fatal shock. OSHA Incident Report # was prepared. 4 It is reasonable to conclude that this incident could have been avoided if the new technology receptacle/attachment fitting technology had been used because the fixture could not have become energized, as there would be no access to electricity through the disconnected fixture. CPSC Data. The CPSC estimates 4 electrocution deaths per year associated with lighting products. 5 CPSC data from the National Electronic Injury Surveillance System (NEISS) database from 2009 to 2013 was analyzed. There were 38 incidents resulting in hospital emergency room visits involving the installation of light fixtures; 32 of those incidents involved falls and at least four of those incidents involved the victims being shocked. With the new technology, after the receptacle is installed in the ceiling, there is no additional wiring necessary, no weight or bulk of the fixture during the initial receptacle installation, and no shock hazard during the quick connect of the fixture. Without the weight/bulk, the falls may not have occurred. With the new technology receptacle in place, installation of the luminaire is a quick connect and no shock would have occurred. 1 Construction Focus Four: Electrocution Hazards, Instructor Guide.

97 There were 418 incidents resulting in hospital emergency room visits involving changing light bulbs; 390 involved falls and at least six of those incidents involved the victims being shocked. Additionally, there were 9 additional incidents resulting in hospital emergency room visits associated with cleaning the light fixture; 8 of those involved falls. It is reasonable to conclude that many of these incidents could have been avoided or minimized if the new technology receptacle/attachment fitting technology had been used. The fixture is simply disconnected and any bulb or fixture maintenance or cleaning can be done on a table, not at an elevation, thereby reducing the time at an elevated level, thereby reducing the hazard. There were 55 incidents resulting in hospital emergency room visits involving a luminaire falling from the ceiling onto the victim. It is reasonable to conclude that many of these incidents could have been avoided or minimized if the receptacle/attachment fitting technology had been used. The new technology has redundant double locking mechanisms that each holds 200 lbs (although they would never hold more than 50 lb, the standard weight of a fixture), therefore the fixtures would not fall. NIOSH DATA. The National Institute for Occupational Safety and Health (NIOSH) conducts the Fatal Accident Circumstances and Epidemiology (FACE) Project. Data are collected from a sample of fatal accidents, including electrical-related fatalities. NIOSH FACE Report summarized a 1988 electrocution of a Virginia electrician. He contacted an energized wire while attempting to install a floodlight on a new residential home. The initial wiring was complete and the electrician was wiring the fixture. The victim, using insulated wire strippers, began removing the insulation from the "14-2" standard house wiring (i.e., a cable containing two copper wires, size number 14) when his right thumb and right index finger contacted the uninsulated part of the wire stripper. The 110-volt circuit had not been deenergized at the panel box prior to the incident. The victim received an electrical shock and fell to the ground. It is reasonable to conclude that this incident might have been avoided if the new technology receptacle/attachment fitting technology had been used. It is likely that some of the electrician s attention was diverted to the light as he was likely holding the light to connect it after the preparation of the wires. If the new technology were used, the receptacle would ve already been installed, and the fixture would ve simply been quick- connected with the receptacle and attachment fitting. If the new technology had been used, the electrocution could ve been avoided. NIOSH FACE Report summarized a 1987 electrocution of a North Carolina electrician. While repairing a fluorescent light fixture over a kitchen sink in a single-family residence, a 33-6 NIOSH Face Reports 1982 to 2005 including can be found at FACE/Default.cshtml?state=ALL&Incident_Year=ALL&Category2=0006&Submit=Submit#.VFjs8y7-DK0. . This particular report can be located directly at 7 NIOSH Face Reports 1982 to 2005 including can be found at FACE/Default.cshtml?state=ALL&Incident_Year=ALL&Category2=0006&Submit=Submit#.VFjs8y7-DK0. . This particular report can be located directly at 4 P age

98 year-old journeyman electrician was electrocuted when he contacted an energized wire on the load side of the ballast (400 volts). The ballast had been replaced, however, he could not get the light to operate properly. The electrician was sitting on the sink when he apparently contacted an energized wire on the load side of the ballast. The circuit had not been de-energized at the panel box or at the single-pole switch on the wall beside the sink. It is reasonable to conclude that this incident might have been avoided if the new technology receptacle/attachment fitting technology had been used. The receptacle would ve already been installed, and the fixture could ve been taken down through a simple quick disconnect for examination. If the fixture was determined to be in working order, additional work could be completed with the fixture quick-disconnected and out of the vicinity so full attention could be given to the wiring. If the new technology had been used, the electrocution might have been avoided. Efficiency Improvements. The technology will increase not only electricians safety but efficiency in installation. The installation of luminaires and ceiling fans requires the simultaneous support of the heavy and bulky appliance while properly performing the connection of the wiring. During the installation, the electrician has to do the wiring while he or someone else is holding the bulky luminaire or fan. This is not the case with this new technology. With this new technology, the receptacle is installed to the ceiling outlet box, completing the wiring of the branch circuit through the receptacle unit. The electrician then installs a cover plate, just as with other receptacle types. To complete the installation, the luminaire or fan with the attached plug is simply quick connected into the receptacle and the luminaire or ceiling fan installation is complete. Wiring will no longer require the luminaire or fan to be held nearby, oftentimes while on a ladder. By removing the bulky luminaire or ceiling fan from the initial equation, safety and efficiency is increased. 5 P age

The attachment fitting is a recognized component used as part of a listed product. The attachment fitting is inserted in a listed receptacle. This Public Input is part of series of Public Inputs submitted to assure that this new third party certified combination is recognized by users and inspectors, and installed in a consistent and safe manner. There are 5 topics addressed in this substantiation: 1) Why new NEC text is needed; 2) explanation of the new technology; 3) what problem is being solved by adding new text; 4) relevant fatality and injury data; and 5) documentation that there are no essential patent concerns. Why new NEC text is necessary. This multifunctional receptacle and attachment fitting (not plug) combination is a new technology category and is not intended to be product or manufacturer specific. It should be noted that the attachment fitting is not a plug since it is used as part of a listed utilization device (luminaire or paddle fan). The technology is a load-bearing receptacle that is a quick connect and disconnect method that allows for safe wiring, installation and removal for ceiling mounted luminaires and ceiling fans. Once the receptacle and cover plate are in place, since the luminaire is disconnected from the power source until plugged in and there are not exposed energized parts, installation and connection of the utilization equipment (luminaire or paddle fan) is inherently safe. By adding this new section to address the new technology, it is easier for inspectors, installers and others to recognize, understand and assess this new technology and method of installation. Additionally for installers, it represents technology that eliminates or reduces electrical hazards in many common instances described in the Data portion of this substantiation. An example of this type of technology is the GE/Safety Quick Lighting and Fans Corp (SQL) product, of which over a million of these units were sold between 2007 and It is projected that availability and recognition of the technology will significantly increase usage. As the popularity of the technology grows, it is reasonable to assume other designs of the locking support and mounting receptacle and attachment fitting combination will arise. It is requested that the NEC Panels proactively recognize the new technology, as it will be in wide use and it will increase safety. Examples of new technology that have been acknowledged in the NEC past include wind turbines and electric vehicle charging systems in order to keep up with advances in the state-of-the-art electrical technologies. 1 P age

111 Ensuring Recognition of Appropriate NEC Requirements and Safe Installation. When the technology was submitted to UL to obtain a listing, it was initially placed in the New and Unusual category. As such, it was submitted to UL s Electrical Council, and after much review and discussion, the technology was determined to be a receptacle and fitting (not plug) combination, and was successfully listed to UL 498, Attachment Plugs and Receptacles. Considering UL s extensive steps used to categorize and evaluate the technology, it is foreseeable that others might not realize that this technology is indeed considered a receptacle and fitting (not plug) combination, nor understand the requirements for electrical safety unless the technology is clearly addressed in the NEC. This new technology combination of receptacle and attachment fitting cannot be electrically overloaded because an appropriate fitting will always be matched with the utilization device as part of its construction in accordance with its third party certification. Data from Consumer Products Safety Commission (CPSC), National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) show that the traditional methods of changing an existing luminaire or maintaining existing luminaires can be dangerous. This technology significantly reduces and in many cases eliminates these hazards. For these reasons, the technology should be addressed in the NEC. What is the technology? The technology is different than what is currently addressed in Article 406. The technology is a load-bearing receptacle that is a quick connect and disconnect method for ceiling mounted luminaires and ceiling fans. By adding this new section to address the new technology, the receptacle and attachment fitting combination, it allows inspectors to recognize what requirements govern the technology therefore they can easily understand and assess this new technology and method of installation. Although the suggested text is not intended to be product or manufacturer specific, an example of this technology from GE/SQL can be seen in the photo provided; a video describing the new technology can also be seen at With this new technology, the receptacle is installed to the ceiling outlet box, completing the wiring of the branch circuit through the receptacle unit. The electrician then installs a cover plate, just as with other receptacle types. To complete the installation, the luminaire or fan, by means of the attachment fitting that is part of the utilization equipment, is simply quick connected into the receptacle and the luminaire or ceiling fan installation is complete. What problem is being solved? By adding the new text, there is clear categorization of the new technology and the requirements to ensure electrical safety by electricians and inspectors. By adding this new section to address the new technology, it is safer and easier for installers, inspectors and others to recognize, understand and assess this new technology and method of installation to the appropriate requirements of the NEC. Intuitively we understand that not having to rewire each unit when the luminaire or ceiling fan is changed is safer, and there are data from CPSC, NIOSH and OSHA to confirm this notion. When an electrician installs the receptacle (female unit), it is mounted on a variation of the traditional crossbar. The attachment fitting (male fitting) is attached by the manufacturer to the luminaire, and is not available without attachment to a listed appliance. Thereby facilitating and increasing safety when the electrician installs the luminaire. Similar to the use of a ballast disconnect, this 2 P age

112 combination works to minimize or eliminate risk associated with electrical shock and associated injuries, especially when the use of ladders and support of devices are involved, or when the utilization device itself needs to be worked on. Relevant Fatality and Injury Data. OSHA Data. In the OSHA electrocution training materials, an OSHA Fatal Fact is presented 1 that details a union electrician s death by electrocution during trouble shooting with lamps. If the technology was used, the lamps could ve been disconnected and troubleshooting take place without the presence of electrical hazards. There is an OSHA Incident Report # Another OSHA Incident Report 3 # summarizes a 2008 electrocution of an electrician while changing a light bulb. It is reasonable to conclude that this incident could have been avoided if the new technology receptacle/attachment fitting technology had been used. The fixture would ve been disconnected and a new bulb would be inserted into the disconnected fixture with no access to electricity. In 2011, an electrician was electrocuted when the wires of a light fixture he was attempting to hang became stripped energizing the light fixture. As he grabbed one of the attached steel hanging cables, he received a fatal shock. OSHA Incident Report # was prepared. 4 It is reasonable to conclude that this incident could have been avoided if the new technology receptacle/attachment fitting technology had been used because the fixture could not have become energized, as there would be no access to electricity through the disconnected fixture. CPSC Data. The CPSC estimates 4 electrocution deaths per year associated with lighting products. 5 CPSC data from the National Electronic Injury Surveillance System (NEISS) database from 2009 to 2013 was analyzed. There were 38 incidents resulting in hospital emergency room visits involving the installation of light fixtures; 32 of those incidents involved falls and at least four of those incidents involved the victims being shocked. With the new technology, after the receptacle is installed in the ceiling, there is no additional wiring necessary, no weight or bulk of the fixture during the initial receptacle installation, and no shock hazard during the quick connect of the fixture. Without the weight/bulk, the falls may not have occurred. With the new technology receptacle in place, installation of the luminaire is a quick connect and no shock would have occurred. 1 Construction Focus Four: Electrocution Hazards, Instructor Guide.

113 There were 418 incidents resulting in hospital emergency room visits involving changing light bulbs; 390 involved falls and at least six of those incidents involved the victims being shocked. Additionally, there were 9 additional incidents resulting in hospital emergency room visits associated with cleaning the light fixture; 8 of those involved falls. It is reasonable to conclude that many of these incidents could have been avoided or minimized if the new technology receptacle/attachment fitting technology had been used. The fixture is simply disconnected and any bulb or fixture maintenance or cleaning can be done on a table, not at an elevation, thereby reducing the time at an elevated level, thereby reducing the hazard. There were 55 incidents resulting in hospital emergency room visits involving a luminaire falling from the ceiling onto the victim. It is reasonable to conclude that many of these incidents could have been avoided or minimized if the receptacle/attachment fitting technology had been used. The new technology has redundant double locking mechanisms that each holds 200 lbs (although they would never hold more than 50 lb, the standard weight of a fixture), therefore the fixtures would not fall. NIOSH DATA. The National Institute for Occupational Safety and Health (NIOSH) conducts the Fatal Accident Circumstances and Epidemiology (FACE) Project. Data are collected from a sample of fatal accidents, including electrical-related fatalities. NIOSH FACE Report summarized a 1988 electrocution of a Virginia electrician. He contacted an energized wire while attempting to install a floodlight on a new residential home. The initial wiring was complete and the electrician was wiring the fixture. The victim, using insulated wire strippers, began removing the insulation from the "14-2" standard house wiring (i.e., a cable containing two copper wires, size number 14) when his right thumb and right index finger contacted the uninsulated part of the wire stripper. The 110-volt circuit had not been deenergized at the panel box prior to the incident. The victim received an electrical shock and fell to the ground. It is reasonable to conclude that this incident might have been avoided if the new technology receptacle/attachment fitting technology had been used. It is likely that some of the electrician s attention was diverted to the light as he was likely holding the light to connect it after the preparation of the wires. If the new technology were used, the receptacle would ve already been installed, and the fixture would ve simply been quick- connected with the receptacle and attachment fitting. If the new technology had been used, the electrocution could ve been avoided. NIOSH FACE Report summarized a 1987 electrocution of a North Carolina electrician. While repairing a fluorescent light fixture over a kitchen sink in a single-family residence, a 33-6 NIOSH Face Reports 1982 to 2005 including can be found at FACE/Default.cshtml?state=ALL&Incident_Year=ALL&Category2=0006&Submit=Submit#.VFjs8y7-DK0. .

This particular report can be located directly at 4 P age

114 year-old journeyman electrician was electrocuted when he contacted an energized wire on the load side of the ballast (400 volts). The ballast had been replaced, however, he could not get the light to operate properly. The electrician was sitting on the sink when he apparently contacted an energized wire on the load side of the ballast. The circuit had not been de-energized at the panel box or at the single-pole switch on the wall beside the sink. It is reasonable to conclude that this incident might have been avoided if the new technology receptacle/attachment fitting technology had been used. The receptacle would ve already been installed, and the fixture could ve been taken down through a simple quick disconnect for examination. If the fixture was determined to be in working order, additional work could be completed with the fixture quick-disconnected and out of the vicinity so full attention could be given to the wiring. If the new technology had been used, the electrocution might have been avoided. Efficiency Improvements. The technology will increase not only electricians safety but efficiency in installation. The installation of luminaires and ceiling fans requires the simultaneous support of the heavy and bulky appliance while properly performing the connection of the wiring. During the installation, the electrician has to do the wiring while he or someone else is holding the bulky luminaire or fan. This is not the case with this new technology. With this new technology, the receptacle is installed to the ceiling outlet box, completing the wiring of the branch circuit through the receptacle unit. The electrician then installs a cover plate, just as with other receptacle types. To complete the installation, the luminaire or fan with the attached plug is simply quick connected into the receptacle and the luminaire or ceiling fan installation is complete. Wiring will no longer require the luminaire or fan to be held nearby, oftentimes while on a ladder. By removing the bulky luminaire or ceiling fan from the initial equation, safety and efficiency is increased. 5 P age

Additionally for installers, it represents technology that eliminates or reduces electrical hazards in many common instances described in the Data portion of this substantiation. An example of this type of technology is the GE/Safety Quick Lighting and Fans Corp (SQL) product, of which over a million of these units were sold between 2007 and It is projected that availability and recognition of the technology will significantly increase usage. As the popularity of the technology grows, it is reasonable to assume other designs of the locking support and mounting receptacle and attachment fitting combination will arise. It is requested that the NEC Panels proactively recognize the new technology, as it will be in wide use and it will increase safety. Examples of new technology that have been acknowledged in the NEC past include wind turbines and electric vehicle charging systems in order to keep up with advances in the state-of-the-art electrical technologies. 1 P age

127 Ensuring Recognition of Appropriate NEC Requirements and Safe Installation. When the technology was submitted to UL to obtain a listing, it was initially placed in the New and Unusual category. As such, it was submitted to UL s Electrical Council, and after much review and discussion, the technology was determined to be a receptacle and fitting (not plug) combination, and was successfully listed to UL 498, Attachment Plugs and Receptacles. Considering UL s extensive steps used to categorize and evaluate the technology, it is foreseeable that others might not realize that this technology is indeed considered a receptacle and fitting (not plug) combination, nor understand the requirements for electrical safety unless the technology is clearly addressed in the NEC. This new technology combination of receptacle and attachment fitting cannot be electrically overloaded because an appropriate fitting will always be matched with the utilization device as part of its construction in accordance with its third party certification. Data from Consumer Products Safety Commission (CPSC), National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) show that the traditional methods of changing an existing luminaire or maintaining existing luminaires can be dangerous. This technology significantly reduces and in many cases eliminates these hazards. For these reasons, the technology should be addressed in the NEC. What is the technology? The technology is different than what is currently addressed in (B). The technology is a load-bearing receptacle that is a quick connect and disconnect method for ceiling mounted luminaires and ceiling fans. By adding this new section to address the new technology, the receptacle and attachment fitting combination, it allows inspectors to recognize what requirements govern the technology therefore they can easily understand and assess this new technology and method of installation. Although the suggested text is not intended to be product or manufacturer specific, an example of this technology from GE/SQL can be seen in the photo provided; a video describing the new technology can also be seen at With this new technology, the receptacle is installed to the ceiling outlet box, completing the wiring of the branch circuit through the receptacle unit. The electrician then installs a cover plate, just as with other receptacle types. To complete the installation, the luminaire or fan, by means of the attachment fitting that is part of the utilization equipment, is simply quick connected into the receptacle and the luminaire or ceiling fan installation is complete. What problem is being solved? By adding the new text, there is clear categorization of the new technology and the requirements to ensure electrical safety by electricians and inspectors. By adding this new section to address the new technology, it is safer and easier for installers, inspectors and others to recognize, understand and assess this new technology and method of installation to the appropriate requirements of the NEC. Intuitively we understand that not having to rewire each unit when the luminaire or ceiling fan is changed is safer, and there are data from CPSC, NIOSH and OSHA to confirm this notion. When an electrician installs the receptacle (female unit), it is mounted on a variation of the traditional crossbar. The attachment fitting (male fitting) is attached by the manufacturer to the luminaire, and is not available without attachment to a listed appliance. Thereby facilitating and increasing safety when the electrician installs the luminaire. Similar to the use of a ballast disconnect, this 2 P age

128 combination works to minimize or eliminate risk associated with electrical shock and associated injuries, especially when the use of ladders and support of devices are involved, or when the utilization device itself needs to be worked on. Relevant Fatality and Injury Data. OSHA Data. In the OSHA electrocution training materials, an OSHA Fatal Fact is presented 1 that details a union electrician s death by electrocution during trouble shooting with lamps. If the technology was used, the lamps could ve been disconnected and troubleshooting take place without the presence of electrical hazards. There is an OSHA Incident Report # Another OSHA Incident Report 3 # summarizes a 2008 electrocution of an electrician while changing a light bulb. It is reasonable to conclude that this incident could have been avoided if the new technology receptacle/attachment fitting technology had been used. The fixture would ve been disconnected and a new bulb would be inserted into the disconnected fixture with no access to electricity. In 2011, an electrician was electrocuted when the wires of a light fixture he was attempting to hang became stripped energizing the light fixture. As he grabbed one of the attached steel hanging cables, he received a fatal shock. OSHA Incident Report # was prepared. 4 It is reasonable to conclude that this incident could have been avoided if the new technology receptacle/attachment fitting technology had been used because the fixture could not have become energized, as there would be no access to electricity through the disconnected fixture. CPSC Data. The CPSC estimates 4 electrocution deaths per year associated with lighting products. 5 CPSC data from the National Electronic Injury Surveillance System (NEISS) database from 2009 to 2013 was analyzed. There were 38 incidents resulting in hospital emergency room visits involving the installation of light fixtures; 32 of those incidents involved falls and at least four of those incidents involved the victims being shocked. With the new technology, after the receptacle is installed in the ceiling, there is no additional wiring necessary, no weight or bulk of the fixture during the initial receptacle installation, and no shock hazard during the quick connect of the fixture. Without the weight/bulk, the falls may not have occurred. With the new technology receptacle in place, installation of the luminaire is a quick connect and no shock would have occurred. 1 Construction Focus Four: Electrocution Hazards, Instructor Guide.

129 There were 418 incidents resulting in hospital emergency room visits involving changing light bulbs; 390 involved falls and at least six of those incidents involved the victims being shocked. Additionally, there were 9 additional incidents resulting in hospital emergency room visits associated with cleaning the light fixture; 8 of those involved falls. It is reasonable to conclude that many of these incidents could have been avoided or minimized if the new technology receptacle/attachment fitting technology had been used. The fixture is simply disconnected and any bulb or fixture maintenance or cleaning can be done on a table, not at an elevation, thereby reducing the time at an elevated level, thereby reducing the hazard. There were 55 incidents resulting in hospital emergency room visits involving a luminaire falling from the ceiling onto the victim. It is reasonable to conclude that many of these incidents could have been avoided or minimized if the receptacle/attachment fitting technology had been used. The new technology has redundant double locking mechanisms that each holds 200 lbs (although they would never hold more than 50 lb, the standard weight of a fixture), therefore the fixtures would not fall. NIOSH DATA. The National Institute for Occupational Safety and Health (NIOSH) conducts the Fatal Accident Circumstances and Epidemiology (FACE) Project. Data are collected from a sample of fatal accidents, including electrical-related fatalities. NIOSH FACE Report summarized a 1988 electrocution of a Virginia electrician. He contacted an energized wire while attempting to install a floodlight on a new residential home. The initial wiring was complete and the electrician was wiring the fixture. The victim, using insulated wire strippers, began removing the insulation from the "14-2" standard house wiring (i.e., a cable containing two copper wires, size number 14) when his right thumb and right index finger contacted the uninsulated part of the wire stripper. The 110-volt circuit had not been deenergized at the panel box prior to the incident. The victim received an electrical shock and fell to the ground. It is reasonable to conclude that this incident might have been avoided if the new technology receptacle/attachment fitting technology had been used. It is likely that some of the electrician s attention was diverted to the light as he was likely holding the light to connect it after the preparation of the wires. If the new technology were used, the receptacle would ve already been installed, and the fixture would ve simply been quick- connected with the receptacle and attachment fitting. If the new technology had been used, the electrocution could ve been avoided. NIOSH FACE Report summarized a 1987 electrocution of a North Carolina electrician. While repairing a fluorescent light fixture over a kitchen sink in a single-family residence, a 33-6 NIOSH Face Reports 1982 to 2005 including can be found at FACE/Default.cshtml?state=ALL&Incident_Year=ALL&Category2=0006&Submit=Submit#.VFjs8y7-DK0. .

130 year-old journeyman electrician was electrocuted when he contacted an energized wire on the load side of the ballast (400 volts). The ballast had been replaced, however, he could not get the light to operate properly. The electrician was sitting on the sink when he apparently contacted an energized wire on the load side of the ballast. The circuit had not been de-energized at the panel box or at the single-pole switch on the wall beside the sink. It is reasonable to conclude that this incident might have been avoided if the new technology receptacle/attachment fitting technology had been used. The receptacle would ve already been installed, and the fixture could ve been taken down through a simple quick disconnect for examination. If the fixture was determined to be in working order, additional work could be completed with the fixture quick-disconnected and out of the vicinity so full attention could be given to the wiring. If the new technology had been used, the electrocution might have been avoided. Efficiency Improvements. The technology will increase not only electricians safety but efficiency in installation. The installation of luminaires and ceiling fans requires the simultaneous support of the heavy and bulky appliance while properly performing the connection of the wiring. During the installation, the electrician has to do the wiring while he or someone else is holding the bulky luminaire or fan. This is not the case with this new technology. With this new technology, the receptacle is installed to the ceiling outlet box, completing the wiring of the branch circuit through the receptacle unit. The electrician then installs a cover plate, just as with other receptacle types. To complete the installation, the luminaire or fan with the attached plug is simply quick connected into the receptacle and the luminaire or ceiling fan installation is complete. Wiring will no longer require the luminaire or fan to be held nearby, oftentimes while on a ladder. By removing the bulky luminaire or ceiling fan from the initial equation, safety and efficiency is increased. 5 P age

134 Substantiation: This Public Input seeks to modify Section (F) to support proposed new Section that provides requirements for the new technology. This is one of 3 linked Public Inputs: the second PI creates a new Section to provide requirements for the new technology and a third PI creates a new associated definition for Attachment Fitting. Similar sets of Public Inputs were submitted in the event the Panel wished to consider two alternate locations for adding this new technology, including submitting the same concepts to Sections (C) as well as another set to insert a new (B). There is a new third party certified combination that includes the use of a receptacle and an attachment fitting to supply, support and connect ceiling- or wall-luminaires and ceilingsuspended luminaires, and ceiling-suspended (paddle) fans. The attachment fitting is a recognized component used as part of a listed product. The attachment fitting is inserted in a listed receptacle. This Public Input is part of series of Public Inputs submitted to assure that this new third party certified combination is recognized by users and inspectors, and installed in a consistent and safe manner. There are 5 topics addressed in this substantiation: 1) Why new NEC text is needed; 2) explanation of the new technology; 3) what problem is being solved by adding new text; 4) relevant fatality and injury data; and 5) documentation that there are no essential patent concerns. Why new NEC text is necessary. This multifunctional receptacle and attachment fitting (not plug) combination is a new technology category and is not intended to be product or manufacturer specific. It should be noted that the attachment fitting is not a plug since it is used as part of a listed utilization device (luminaire or paddle fan). The technology is a load-bearing receptacle that is a quick connect and disconnect method that allows for safe wiring, installation and removal for ceiling mounted luminaires and ceiling fans.

147 557 of /18/2014 2:46 PM Public Input No NFPA [ Part XIII. ] Part XIII. Grounding Bonding All Voltages The term equipment grounding conductor is a misnomer even though it has been in use for many many years. Although it is a grounded conductor in normal practice for grounded systems, the idea that grounding makes a system safe and prevents an electrical shock is inherently false. Connecting a conductor from metallic equipment likely to become energized to the earth does not reduce the shock potential during a fault but, rather, may enhance it if it becomes the only path back to the source. The shock potential is the voltage drop along the conductor (equipment grounding conductor) due to fault current flowing back to the source. The shock hazard depends upon the time until the fault is cleared by an overcurrent device or some other event, thus the clearing time is a critical factor in safety. This conductor (equipment grounding conductor) is intended to protect equipment and personnel by providing a sufficiently high fault current to operate an overcurrent device and clear the fault rapidly. A low impedance fault current path can provide the necessary high fault current regardless of whether the conductor is grounded or not. It is only the fault current path and not the grounding that can provide the high fault current necessary to operate an overcurrent device rapidly. The term bonding is generally used to insure that a connection and current path is low impedance, reliable, and able to withstand the fault current. This conductor provides a basic bonding function by insuring, through proper sizing and bonding jumpers as necessary, that the connection from equipment to fault current source is both low impedance and reliable. A bonding function is the necessary function rather than a grounding function to clear a fault rapidly. A grounding function is provided by a grounding electrode conductor that connects an electrical system source to the earth. An overcurrent device operates in a time interval based upon the current through it. That current depends upon proper bonding to the source and is relatively independent of connection to the grounding electrode at the source where the overcurrent device is located. The use of the term equipment bonding conductor would better describe the function of this important conductor instead of the term equipment grounding conductor. Systems are grounded, equipment is bonded. Making this change would also bring the NEC into conformity with the Canadian Electrical Code which uses the term equipment bonding conductor. Code Panel 5 members have often stated that those in the industry understand what the purpose of the equipment grounding conductor is for. The Panel members understand this also. There are, however, many people doing electrical work who don t understand and think connecting equipment to a local grounding electrode accomplishes the same objective as an equipment grounding conductor. This is apparent from the large number of questions that are asked at IAEI inspectors meetings, grounding classes, and as documented recently in the July/August 2014 issue of the NFPA Journal under the title Pool Rules. Just ask the inspectors and the teachers. Changing the terminology will serve to make it clear that the principal function of this conductor is to bond the equipment being protected to the source where the fault current originates. Changing the terminology will not confuse those that understand the proper purpose of this bonding conductor.

179 361 of /18/2014 2:46 PM Public Input No. 836-NFPA [ New Section after ] New Ground and Bonding. Where equipment is installed outdoors on a roof, a grounding conductor of the wire type shall be installed in metallic raceway systems that use non-threaded fittings. Exception No. 1 In industrial installations, with written safety procedures, where conditions of maintenance and supervision ensure that only qualified persons service the equipment. Conduits installed per code over a period of time are stepped on, moved for re-roofing jobs, snow removal, etc. This supplemental ground would ensure that continuity will be maintained if and when the conduit separates. There have many instances where the conduit has separated and the hot wire insulation has been compromised thus energizing the conduit. Reaching down and attempting to put the conduit back together can cause a current path through the heart. From our own experience we have seen this happen and only because of proper safety practices has disaster been avoided. This is subjecting installers to unnecessary hazards. Numerous state codes now require a supplement ground in any conduit running across a roof. The argument that this type of raceway system should not have been installed because it is exposed to damage does not take into account that these systems have been installed on roofs for many years and are an accepted installation practice. This proposal is not to say that non-threaded systems are not good ground return paths, but this will ensure the safety of anyone that may be working on the roof and servicing the raceway/equipment.

180 358 of /18/2014 2:46 PM Public Input No NFPA [ New Section after ] TITLE OF NEW CONTENT New Section Rooftops. Electrical Metal Tubing shall not be permitted for rooftop HVAC installations. It is an undisputed fact that after installation, EMT installed on rooftops is often subjected to severe physical damage. Damage to the EMT that causes the couplings or connectors to separate from the tubing results in an unsafe condition for personnel, because the EMT is permiited to be used as an equipment grounding conductor per and , but now is ineffective to clear a ground fault, and would leave the HVAC unit or the EMT energized in a ground-fault condition. The damage that occurs after installation usually comes from snow removal equipment, or persons re-roofing the building. The EMT is secured to the existing rooftop, and either isn't seen under the snow; or is in the way for roofers, and must be lifted or moved out of the way in order for the new roof to be installed. During these activities, the EMT is moved and couplers / connectors are often separated. Concerns raised and Code proposals submitted to address this issue have been responded to in this manner, that EMT is not permitted per - "Section (1). Where, during installation or afterward, it will be subject to severe physical damage." Past proposals to correct the unsafe condition of no equipment grounding to the HVAC unit because the tubing couplings or connectors are separated or broken - have been met with the response - " don't install the EMT where it will be subject to severe physical damage". Okay, understood. Since proposals to add a simple equipment grounding conductor to the branch circuit or feeder have not made it into the NEC, it is only logical to conclude that: 1. An equipment grounding conductor installed in the rooftop raceway is not required in EMT to improve the safety of the installation because the raceway is fully qualified as an EGC and stands on its own. 2. EMT is not permitted to be installed where subject to severe physical damage. 3. EMT is acknowledged to be subject to severe physical damage when installed on a rooftop. 4. Therefore, EMT must be prohibited from use for rooftop HVAC installations because it is, more often than not, subjected to severe physical damage. Apparently, we are to conclude that the idea of requiring installing a relatively inexpensive insulated green colored equipment grounding conductor in the EMT raceway to provide safety for personnel is a bad idea? Even though some states and municipalities recognized the personnel safety issue and adopted requirements for an EGC in years ago? The NITMAM regarding the installation of an insulated equipment grounding conductor in EMT for HVAC installations came within 1 vote of passing at the NFPA Annual Meeting in Chicago last year. Please take another look at this, and require the wire type equipment grounding conductor sized in accordance with NEC Section to be installed in the rooftop EMT raceway. Thank you for your thoughtful consideration of this safety issue - it's about personnel safety, which is the stated purpose of the NEC, found in Section In my view, this issue should be about except personnel safety.

181 357 of /18/2014 2:46 PM Public Input No NFPA [ New Section after ] NEW SECTION Where installed on rooftops to supply electrical power to heating, ventilating, or air conditioning equipment, a wire-type equipment grounding conductor shall be included in the wiring method, and sized in accordance with Section EMT - also known as Thinwall tubing - a very useful wiring method. However, when installed on a roof, eventually a roof needs replaced, or snow falls on a roof, and the roofers or snow removal personnel / snowbladers move or strike the EMT with equipment, and often cause it severe physical damage. Severe damage to the EMT causes the couplers to separate sections of EMT, rendering it no longer effective on its own as a ground-fault current path. This severe damage to the EMT can be a serious hazard, as ground-faults do occur on HVAC equipment, particularly when the EMT is severely damaged. I personally know of two electricians who have experienced this. What is the solution? Section states that EMT shall not be installed where subject to physical damage. But, owners and contractors like to use EMT as a wiring method. The issue is to prevent a safety hazard by lack of a ground fault current path. A great solution to this issue is to require a wire type equipment grounding conductor to be installed in the EMT. In the State of Washington, EMT installed in any wet location requires a wire type equipment grounding conductor to be installed in the EMT, and sized accordance with Section This recognizes that EMT is a preferred wiring method, but can have issues with when installed outdoors over a long period of time. Contractors are happy because they can install and use a preferred wiring method, and safety concerns are addressed to help prevent electric shock and fire. Therefore, everyone is happy, and we can do business. Submitter Full Name: MICHAEL WEITZEL Organization: Submittal Date: Fri Sep 19 11:52:17 EDT 2014

183 359 of /18/2014 2:46 PM Public Input No NFPA [ New Section after ] Grounding & Bonding. Outdoor portions of wiring methods that do not utilize threaded couplings and connectors shall include an equipment grounding conductor of the wire type when located on rooftops. Steel electrical conduit and tubing has been shown to be an effective grounding path in many installations spanning several years when installed correctly. However, when installed on rooftops to supply rooftop HVAC equipment, some wiring method installations become compromised resulting in a potential safety issue for workers. This is a result of rooftop activities such as snow removal or roof repair/replacement, activities that take place well after the electrical contractor has left the job-site. When the roofing material is being replaced, the roofing contractor will raise the wiring methods up to a level that allows his employees to work under them. This causes stress at all connections and joints of the wiring method involved, in some cases resulting in a loosened or separated connection at a coupling or connector. A recent study was conducted by the Independent Electrical Contractors (IEC) which determined this to be a commonly encountered problem. Over 50% of the respondents to the survey indicated they had either personally seen or heard from others cases where non-threaded wiring methods had loosened or become separated. 7% of the respondents indicated they received or knew someone who received a serious electrical shock as a result of conduit separation. How many shock incidents were never reported because it was felt to be non-serious? How many shock incidents were avoided altogether due to the installation of a wire-type EGC? The proposal is only addressing wiring methods on rooftops because these are the wiring methods that would be subject to potential damage arising from snow removal or roofing activities. It also only addresses the outdoor portions of the wiring method, since indoors it is not likely to experience physical damage. A junction box could be mounted where the wiring method passes to the roof, and the wire-type equipment grounding conductor (EGC) could begin there by bonding to the box or enclosure. It also exempts wiring methods that utilize threaded connections at couplings and conduits as these are unlikely to separate. This brings me to my final point in support of the proposed language. My position in the electrical trade allows/requires me to travel quite a bit. This enables me to meet with electrical industry representatives throughout the United States; contractors, electricians, etc. In my discussions, with the issue of rooftop equipment grounding in mind, I have made it a point to ask if they install wire-type EGC's in wiring methods in their areas. Overwhelmingly, those that I have asked stated that it is standard practice to install a wire-type EGC in wiring methods. In my area, I work with nearly 40 different contractors that engage in all aspects of the electrical trade - residential, commercial, industrial, telecommunications, etc. and there was not a single one that ever installs a wiring method without also installing a wire-type EGC. The point being that when this issue has come up in past revision cycles, I didn't even know why it was a big deal since in my area we always install the wire-type EGC anyway. To hear some of the arguments against accepting the previous proposals it was implied that this was adding a burdensome amount of additional cost to the project. This is not going to have a severe economic effect, since the portion of the circuit affected is limited to only the rooftop and a lot of installations include the wire-type EGC. This will provide protection for those rare instances that the wiring system installation has been damaged and the wire-type EGC is not installed. Regardless, economics shouldn't even be an argument, because the purpose of the NEC is to safeguard against hazards arising from the use of electricity. This is a safety issue and should be treated as such.

The field marking(s) shall include the date the fault-current calculation was performed and be of sufficient durability to withstand the environment involved. As inspectors, we are having an extremely difficult time enforcing proper short-circuit current ratings of HVAC equipment. The HVAC manufacturers are properly marking the short-circuit current rating on the equipment, but there is typically no information on the job site as to the available short-circuit at the HVAC equipment. If the equipment were marked, in the field, similar to the requirements in NEC , it would be much easier for us to assure that the equipment was being properly protected. We have a responsibility to the business owner to do the best job we can to help assure they are getting a building that is free of electrical hazards. This change would allow us to successfully fulfill that responsibility. Note that this field marking only applies where the equipment is marked with a short-circuit current rating, so it doesn t apply to HVAC units protected at 60 amperes or less, to units for one- and two-family dwellings, or cord-and-attachment-plug connected equipment.
