4 12-1 Log #1170k NEC-P12 Russell LeBlanc, The Peterson School In articles 90 through 830, if the wording is not already there, then add the words (or other structure(s)) after the word BUILDING(S) wherever the intent of the requirement is to also include STRUCTURES as well as buildings. There is a flaw in the NEC. The term "building" is used over 1000 times in the NEC, and in most of the cases the words "or other structure" should follow and apply the same requirements to bridges, billboards, towers, tanks, and other structures that are by definition NOT BUILDINGS. One specific example I can use is section Wiring on Buildings. I believe that this section is also intended to be applied structures, but the wording "or other structures" is not in the heading or the paragraph. There are literally thousands of other instances throughout the code that this same problem exists. This can easily be seen by doing an electronic search for the word "building". In some cases the words "or other structure" (or similar wording) are present, but in the vast majority where the requirements should also be applied to structures other than buildings, the wording is not there Log #921k NEC-P12 Joe Tedesco, Boston, MA The term "adequate" and "adequately" and "inadequately" and "inadequate" should be replaced with terms that can be properly enforced and understood. Terms are not defined and are considered vague and unenforceable per Table in the NEC Style Manaual. They are all "incorrect" 148 times in the NEC Log #2897 NEC-P12 James F. Williams, Fairmont, WV Equipment with electrical components intended to be moved from one place to another. Equipment fed with portable cords or cables intended to be moved from one place to another. The defined term is referenced in several articles of the NEC: 100 I Electric Sign, 110, 210, 250, 368, 400, 430, 490, 500, 501, 505, 511, 513, 514, 515, 516, 517, 518, 520, 525, 530, 545, 600, 640, 668, 680 It is defined in 513.2, 520.2, 530.2, 640.2, & Suggest that a single definition in 100 I is better. In general, Article 100 shall contain definitions of terms that appear in two or more other articles of the. 1

7 12-10 Log #675 NEC-P12 Matthew D. Frederick, City of Mattoon Such disconnecting means shall consist of a motor-circuit switch, circuit breaker, fuseable disconnect, or molded case switch. (4) Placed within view when at the furthest point of travel of the runway contact conductors. Many cranes and hoists run entire lengths of factories. Sometimes this allows hundreds of feet of travel. Most cranes are fed from either end which is also a common place for the disconnect location. This does not always afford the "in view" from every place along the crane rail. The current code is vague. Adding "when at the furthest point of travel" defines better the intent of "in view" without applying the much more defined and restrictive "within sight" as in other sections. A disconnect may be "in view" from the feed end of the crane, but at the furthest point not visible. The current code does not specify what point along the runway contact conductors applies. Furthermore many facilities are designed with fuseable bucket-type disconnects, allowing fuseable disconnects to meet the requirements of only makes sense, as many engineers feel they are superior to breakers or switches Log #303 NEC-P12 Stanley J. Folz, Morse Electric Company (2) Lockable in accordance with Capable of being locked in the open position. The provision for locking or adding a lock to the disconnecting means shall be installed on or at the switch or circuit breaker used as the disconnecting means and shall remain in place with or without the lock installed. Portable means for adding a lock to the switch or circuit breaker shall not be permitted as the means required to be installed at and remain with the equipment. This proposal has been developed by the Usability Task Group assigned by the Technical Correlating Committee. The committee members were Stanley Folz, James Dollard, William Fiske, David Hittinger, Andy Juhasz, Amos Lowrance, Susan Newman-Scearce, Marc Bernsen and Vincent Zinnante. Requirements for a disconnecting means to be lockable in the open position exist in numerous locations in the NEC. A new section has been proposed in Article 110 to consolidate the requirements for a disconnecting means required to be capable of being locked in the open position in a single section for clarity. It is understood that this requirement includes more than disconnecting and locking electrical power sources. This proposal is intended to facilitate a lockout/tagout scenario. It is equally important to ensure that the means for placing the lock remain in place. The concept suggested by this proposal is necessary to provide correlation throughout the NEC with respect to the capability of placing a lock on a disconnecting means to secure it in the open position. 4

The provisions for locking or adding a lock to the disconnecting means shall be installed on or at the switch or circuit breaker used as the disconnecting means and shall remain in place with or without the lock installed. Portable means for adding a lock to the switch or circuit breaker shall not be permitted as the means required to be installed at and remain with the equipment. The rest of this section is to remain the same. This is a companion proposal to one submitted to Code-Making Panel 1 and should be accepted only if said proposal or some equivalent proposal is accepted by Code-Making Panel 1. Said proposal is to put the criteria for a lockable disconnecting means in Article 110 and, thus, be able to eliminate similar repetitions in at least 19 different sections of the NEC. It would also help to standardize the usage of the term "capable of being locked" which has at least four variations in the 2011 NEC Log #304 NEC-P12 Stanley J. Folz, Morse Electric Company A motor-circuit switch, molded-case switch, or circuit breaker shall be provided in the leads from the runway contact conductors or other power supply on all cranes and monorail hoists. The disconnecting means shall be lockable in accordance with capable of being locked in the open position. The provision for locking or adding a lock to the disconnecting means shall be installed on or at the switch or circuit breaker used as the disconnecting means and shall remain in place with or without the lock installed.

The danger sign(s) or label(s) shall comply with (B). This proposal is one of several coordinated companion proposals to provide consistency of danger, caution, and warning sign or markings as required in the NEC. The proposed revision will correlate this danger marking requirement with proposed (B) and the requirements in ANSI Z

10 12-17 Log #999 NEC-P12 James T. Dollard, Jr., IBEW Local Union 98 Replace 600V with 1000V. 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 Log #1000 NEC-P12 James T.

I see a potential typing error in this NEC section. I believe it should read 42 volts ac and not dc. What struck me was the fact that the rms calculation revealed the following: =30. This was a coincidence that I could not ignore so I am making this proposal Log #681 NEC-P12 Andy Juhasz, Kone, Inc (A)(3) (e). Flexible cords and cables in lengths not to exceed 1.8m (6 ft.) that are of a flame-retardant type and located to be protected from physical damage under normal usage shall be permitted in these rooms and spaces without being in stalled in a raceway. They shall be part of the following: (1) Listed equipment (2) A driving machine, or (3) A driving machine brake and located to be protected from physical damage is highly subjective and has been interpreted differently by individual AHJs. Change will limit scope if interpretation and allow for consistent application of the rule Log #1782 NEC-P12 George M. Stolz, II, Quicksilver Electrical Training Add the following text after the existing language: Receptacles for sump pumps shall not be connected to this circuit. This proposal is intended to clarify whether a sump pump can be connected to this circuit. As it stands, a receptacle serving a pump is technically a receptacle in the pit, which appears to defeat the intent of this section. 14

18 12-32 Log #1001 NEC-P12 James T. Dollard, Jr., IBEW Local 98 Replace 600V with 1000V. 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 Log #307 NEC-P12 Stanley J. Folz, Morse Electric Company The disconnecting means shall be an enclosed externally operable fused motor circuit switch or circuit breaker that is lockable in accordance with capable of being locked in the open position. The provision for locking or adding a lock to the disconnecting means shall be installed on or at the switch or circuit breaker used as the disconnecting means and shall remain in place with or without the lock installed. Portable means for adding a lock to the switch or circuit breaker shall not be permitted as the means required to be installed at and remain with the equipment. The disconnecting means shall be a listed device. This proposal has been developed by the Usability Task Group assigned by the Technical Correlating Committee. The committee members were Stanley Folz, James Dollard, William Fiske, David Hittinger, Andy Juhasz, Amos Lowrance, Susan Newman-Scearce, Marc Bernsen and Vincent Zinnante. Requirements for a disconnecting means to be lockable in the open position exist in numerous locations in the NEC. A new section has been proposed in Article 110 to consolidate the requirements for a disconnecting means required to be capable of being locked in the open position in a single section for clarity. It is understood that this requirement includes more than disconnecting and locking electrical power sources. This proposal is intended to facilitate a lockout/tagout scenario. It is equally important to ensure that the means for placing the lock remain in place. The concept suggested by this proposal is necessary to provide correlation throughout the NEC with respect to the capability of placing a lock on a disconnecting means to secure it in the open position. 15

The rest of this section is to remain the same. This is a companion proposal to one submitted to Code-Making Panel 1 and should be accepted only if said proposal or some equivalent proposal is accepted by Code-Making Panel 1. Said proposal is to put the criteria for a lockable disconnecting means in Article 110 and, thus, be able to eliminate similar repetitions in at least 19 different sections of the NEC. It would also help to standardize the usage of the term "capable of being locked" which has at least four variations in the 2011 NEC Log #306 NEC-P12 Stanley J.

When the motor controller is located in the elevator hoistway the disconnecting means required by (A) shall be located in a machinery space, machinery room, control space or control room outside the hoistway; and an additional fused or non-fused enclosed externally-operable motor circuit switch capable of being locked in the open position to disconnect all ungrounded main power-supply conductors shall be located within sight of the motor controller. The additional switch shall be a listed device, and shall comply with (C). When motor controllers are a) installed within the elevator hoistway and b) not supplied with a means for protection from internal short circuits, the option to add fuses to the additional motor circuit switch in (C )(1) would provide a safe and clearly-recognized means to access fuses dedicated for protection of that motor controller. Selective coordination of overcurrent protection is still required. 18
