1 Significant Changes to the Philippine Electrical Code 2009 Edition Jaime V. Mendoza, MTM Board Member

2 2 PEC 2009 (8 th Edition) BEE Resolution No. 12 Series of 2009 Adoption of the Revised (8 th Edition) Philippine Electrical Code Part I as Part of the Rules and Regulations Concerning the Practice of Electrical Engineering and as Referral Code in Accordance with the National Building Code Sept. 14, Published in the Philippine Star last February 18, 2010 (Thursday) page B-10

3 3 R. A An Act For, A More Responsive and Comprehensive Regulation For the Practice, Licensing, and Registration of Electrical Engineers and Electricians. Sec. 4 Powers and Duties of the Board The Board shall exercise executive /administrative or quasi-legislative (rule- making) or quasi-judicial (investigative) powers in carrying out the provisions of this Act.

4 4 Powers of the Board Sec. 29. Revocation of Certificates of Registration and Suspension from the Practice of the Profession. The Board shall have the power, upon proper notice and hearing, to revoke any certificate of registration of any registrant, to suspend him from the practice of the profession or to reprimand him for any specified in the preceding section, or for the use of perpetration of any fraud or deceit in obtaining a certificate of registration, or for gross negligence or incompetence or for unprofessional or dishonorable conduct, for violation of this Act, the rules and regulations and other policies of the Board and the Code of Professional Ethics.

5 5 Licensing Definition a permission granted by competent authority to engage in a practice of profession or business or in an activity. A PEE who designed, signed, and sealed an electrical plans means he/she guaranteed the safety of the electrical plans for 15 years in accordance to Civil Code. PEE, REE or RME who signed as in-charge of installations also guaranteed the safety of the electrical installations for 15 years. You can only guaranteed the safety of your electrical designs/installations if you are well-versed in the Philippine Electrical Code. Licensing guarantees the safety of your works!!!!

6 6 THE PHILIPPINE ELECTRICAL CODE KEY TO SAFETY AND FIRE PREVENTION PURPOSE OF PEC The primary objective of the code is to establish basic materials quality and electrical works standards for the safe use of electricity for light, heat, power, communications, signaling and for other purposes. Practical safeguarding of persons and property from hazards arising from the use of electricity COMPLIANCE TO THE PEC WILL ENSURE SAFETY AND PREVENT ELECTRICAL FIRES

7 7 The Philippine Grid/Distribution Codes Performance Standards Power Quality Reliability System Loss The Philippine Electrical Code Safety Standards Design and Specifications Installation Operation & Maintenance GRID/DISTRIBUTION DEVELOPMENT PLANNING CRITERIA

8 8 THE PHILIPPINE ELECTRICAL CODE The PEC is a safety standard, not a design guide. Electrical designs must comply with the requirements of PEC to ensure safety. Energy management, maintenance, and power quality issues aren t within the scope of the PEC. Consideration should be given for future expansion of electrical systems but this is not a Code requirement.

9 9 Philippine Electrical Code Enforcement 1. This Code is intended for mandatory application by government bodies exercising legal jurisdiction over electrical installation. 2. These government bodies will have the responsibility of implementing the provision of this Code in deciding on the approval of equipment and materials and for granting the special permission contemplated in this Code, where it assured that equivalent objectives can be achieved by establishing and maintaining effective safety.

10 10 Philippine Electrical Code Interpretation Upon recommendation of the Code Committee, the Board of Electrical Engineering shall render the final decision in the interpretation of any portion of the Philippine Electrical Code, in case of controversy.

11 11 The National Electrical Code The first documented case of a Code as a requirement of rules was published on 16 th Nov entitled The Dangers of Electric Lighting. The first NEC was developed in 1897, eighteen after the invention of incandescent light bulb by Thomas A. Edison. Since 1911, the NFPA of Quincy, Massachussets, has been responsible for the maintenance and publication of the NEC. Regularly revised (every three years) to reflect the evolution of products, materials, and installation techniques. 21 Separate Committee, each consisting of persons. Members of each committee meet several times, discuss proposed changes, accepting some and rejecting others, and rewrite (as required) the sections of the Code that were assigned to their committee.

12 12 THE PHILIPPINE ELECTRICAL CODE Code Arrangement

13 13 THE PHILIPPINE ELECTRICAL CODE CLASSIFICATION OF CODE RULES 1. Wiring Design Rules 2. Installation Rules 3. Manufacturing Rules

14 14 THE PHILIPPINE ELECTRICAL CODE CLASSIFICATION OF CODE RULES Wiring design rules used to determine sizes and rating of circuit conductors and devices. Example: 1. Branch circuit conductors supplying a single motor shall have an ampacity not less than 125% of the full-load current. Section The disconnecting means for motor circuits shall have an ampere rating of at least 115% of the full-load current rating of the motor. Section (a)

15 15 THE PHILIPPINE ELECTRICAL CODE CLASSIFICATION OF CODE RULES Installation rules Example: 1. A disconnecting means shall be located within sight from the motor controller. Section In class II Division I Locations, motors, generators, and other rotating electric machinery shall be dust ignition proof or totally enclosed pipe ventilated and shall be approved for class II locations. Sections

16 16 THE PHILIPPINE ELECTRICAL CODE CLASSIFICATION OF CODE RULES Manufacturing rules Example: Section A motor shall be marked with the following information: 1) Manufacturer s Name 2) Rated Volts and Full-load Amperes 3) Rated Frequency and Number of Phases, if an alternating current motor, etc. 4) Rated full-load speed

17 17 The Philippine Electrical Code Various Categories of the Code Rules which apply in a Motor and the Circuits

18 18 ELECTRICAL FIRES If a fault develops, the current (and heat energy) can increase to the extent that either the appliance burns out, the connecting wiring overheats and melts the plastic insulation or the plug and socket may burn out. An electrical fire then occur where the overheated wiring, motor, plug, etc. are in contact with or close to flammable or combustible material. ELECTRICAL FIRE can be defined as a fire where an electric current or electrical fault is found to have been the source of ignition.

19 19 Components that Create a Fire or Explosion combustion Triangle of Fire Very Significant on PEC Installation Rules!!!

20 20 Edition Regularly revised (every three years) to reflect the evolution of products, materials, and installation techniques. 21 Separate Committee, each consisting of persons. Members of each committee meet several times, discuss proposed changes, accepting some and rejecting others, and rewrite (as required) the sections of the Code that were assigned to their committee.

55 55 Branch Circuits A. Tamper-Resistant Receptacles in Dwellings Unit (406.11) (NEC-2008) Why do you think it is a tamperresistant receptacle?..to increase safety for children...maybe that your son, daughter, or grandchildren that you will save

56 56 Branch Circuits A. Tamper-Resistant Receptacles in Dwellings Unit (406.11) (NEC-2008)

57 57 Reorganization Article 2.20 Branch-Circuit, Feeder, and Service Calculations 2000 Article Article 2.20 Part Sections Part Sections I. General I. General II. Feeders and Services III. Optional Calculations for Computing Feeder and Service Loads IV. Method for Computing Farm Loads II. Branch Circuit Load Calculations III. Feeder and Service Load Calculations IV. Optional Feeder And Service Load Calculations V. Farm Calculation

58 58 Universal Change A universal change throughout the 2009 PEC is the replacement of computed load and demand load with calculated load. For example, the term demand load is being replaced with calculated load to improve clarity and to reduce confusion, especially when related to calculated load and demand factor. The term calculated load includes demand factor, the concepts of diversity, and historical data.

59 Service Equipment Disconnecting Means a) Location a) Readily Accessible Location. The service disconnecting means shall be installed at a readily accessible location of a building or a structure. For a building, the service disconnecting means shall be installed either at the outside wall or inside nearest point of entrance of the service conductors to the building.

60 60

61 Service Equipment Disconnecting Means a) Location 2) Bathrooms. Service disconnecting means shall NOT be installed in bathrooms.

62 62

63 63 Article 2.50 Grounding and Bonding The title of Article 2.50 has been changed from Grounding to Grounding and Bonding. Change Significance: The scope of the article clearly covers both grounding and bonding. Adding the term bonding to the title of the article is appropriate, and is consistent with the fact that there are generally as many bonding requirements and provisions included within Article 2.50 as there are grounding requirements, if not more.

64 64

65 Definitions (Revision) Effective Ground-Fault Current Path An intentionally constructed, permanent, low impedance electrically conductive path designed and intended to carry current under ground-fault conditions from the point of a ground fault on a wiring system to the electrical supply source and that facilitates the operation of the overcurrent protective device or groundfault detectors on high-impedance grounded systems.

66 66 Effective Ground-Fault Current Path Metal parts of premises wiring are bonded to an effective ground-fault current path that has sufficiently low impedance to quickly clear line-to-case faults by opening the circuit protection device.

67 67 Effective Ground-Fault Current Path

68 68 Effective Ground-Fault Current Path

69 69 Earth is Not an Effective Ground- Fault Current Path

70 Definitions Ground Fault- An unintentionally, electrically conducting connection between an ungrounded conductor of an electrical circuit and the normally non-current-carrying conductors, metallic enclosures, metallic raceways, metallic, or earth.

71 Definitions Ground-Fault Current Path- An electrically conductive path from the point of ground fault on a wiring system through normally noncurrent-carrying conductors, equipment, or the earth to the electrical supply source.

72 72 Article (b) Main Bonding Jumper Grounding Separately Derived Alternating-Current Systems Buildings or Structures Supplied by Feeder(s) or Branch Circuit(s) Grounding Electrode System and Grounding Electrode Conductor Grounding of Systems and Circuits of 1 kv and Over (High Voltage)

73 Conductors in Parallel The paralleled conductors in each phase, polarity, neutral, or grounded circuit conductor shall comply with all the following: 1. Be the same length 2. Have the same conductor material 3. Be the same size in circular mil area 4. Have the same insulation type 5. Be terminated in the same manner. Why??????.. See FPN:

74 Minimum Size of Conductors The minimum size of conductors shall be as shown in Table , except as permitted elsewhere in this Code. Removal of 10 previous exceptions were not needed

75 Shielding In this section s exception, the voltage has been reduced from 8 kv to 2.4 kv for use of unshielded conductors. Cables operated at a voltage higher than 2.4 kv will now be required to be shielded. Many cable manufacturers specifically recommend against the use of nonshielded cable above 2 kv because of arcing problems and cables without shielding have a very high failure rate.

76 Locations d) Locations Exposed to Direct Sunlight. Insulated conductors and cables used where exposed to direct rays of the sun shall comply with one of the following: (be of a type listed for sunlight resistance or listed and marked sunlight resistant ) 1) Cables listed, or listed and marked, as being sunlight resistant 2) Conductors listed, or listed and marked, as being sunlight resistant 3) Covered with insulating material, such as tape or sleeving, that is listed and marked,as being sunlight resistant.

77 Temperature Limitation of Conductors The PEC 2009 has added a new Fine Print Note with information on derating for conduits on rooftops that have direct sunlight exposures; 17ºC is the indicated value to be added to the outdoor ambient temperature to compensate for the direct solar gain.

78 78

79 (b)(2) Adjustment Factors A new last sentence has been added to (b)(2)(a) to require that individual conductors of paralleled sets be counted as current-carrying conductor. This is intended to clarify varying interpretations of whether each conductor of a paralleled set of conductors is required to be counted individually or if all of the conductors count as one for the purpose of derating. Clearly, each conductor of the parallel set is required to be counted individually for the purposes of rating.

80 80

81 81 Configuration Conductor if Neutral is Counted Derating Percentage Conductors if Neutral is Not Counted Derating Percentage All conductors in single conduit conductors in 3 conduits or cables All conductors in metal wireway or auxiliary gutter All conductors in nonmetallic wireway or auxiliary gutter

82 82 Table (b)(2)(a) Adjustment Factors for More than Three Current- Carrying Conductors in a Raceway or Cable Number of Current- Carrying Conductors and above Percent of Values in Tables Through as Adjusted for Ambient Temperature if Necessary

83 83 Configuration Conductor if Neutral is Counted Derating Percentage Conductors if Neutral is Not Counted Derating Percentage All conductors in single conduit conductors in 3 conduits or cables All conductors in metal wireway or auxiliary gutter All conductors in nonmetallic wireway or auxiliary gutter Not required Not Not 12 required 9 required

84 84 Section (b)(4) (4) Neutral Conductor. a) A neutral conductor that carries only the unbalanced current from other conductors of the same circuit shall not be required to be counted when applying the provisions of Section (b)(2)(a). b) In a 3-wire circuit consisting of two phase wires and the neutral of a 4-wire, 3-phase wye-connected system, a common conductor carries approximately the same current as the lineto-neutral load currents of the other conductors and shall be counted when applying the provisions of Section (b)(2)(a). c) On a 4-wire, 3-phase wye circuit where the major portion of the load consists of nonlinear loads, harmonic currents are present in the neutral conductor; the neutral shall therefore be considered a current-carrying conductor.

85 85 Notes For metal auxiliary gutters, (a) indicates that derating is not required so long as the number of current-carrying conductors at any cross section does not exceed 30. A similar statement is included for sheet metal wireways in Derating for the number of current-carrying conductors in non-metallic auxiliary gutters and wireways is required, beginning at four-current carrying conductors, because conductors in nonmetallic enclosures do not dissipate heat as well as those in sheet-metal enclosures.

86 86 Introduction Art contains many requirements to keep that supply of water uninterrupted. For example: 1. Locating the pump so as to minimize its exposure to fire. 2. Ensuring that the fire pump and its jockey pump have a reliable source of power. 3. It makes sense to keep fire pump wiring independent.

87 87 Introduction Other requirements seem wrong at first glance, until you remember why the fire pump is there in the first place. For example: 1. The disconnect must be lockable in the closed position. 2. Fire pumps power circuits cannot have automatic protection against overload.

88 88 Introduction It s better to run the fire pump until its winding melt, than to save the fire pump and lose the facility And the intent of Article 6.95 is to save the facility.

89 Scope a) Covered 1) Electric power sources and interconnecting circuits 2) Switching and control equipment dedicated to fir pump drivers b) Not Covered 1) The performance, maintenance, and acceptance testing of the fire pump system, and the internal wiring of the components of the system 2) Pressure maintenance (jockey or makeup) pumps

90 Power Sources for Electric-Motor Driven Fire Pumps a) Individual Source 1) Electric Utility Service. A separate service from a connection located ahead of but not within the service disconnecting means. 2) On-Site Power.

The power sources shall be arranged so that a fire at one will not cause an interruption at the other source.

95 Power Sources for Electric-Motor Driven Fire Pumps 2) Feeder Sources

96 Transformers Dedicated transformer and overcurrent protection sizing can be broken down into three requirements. 1. The transformer must be size to at least 125% of the sum of the loads. 2. The transformer primary overcurrent device must be at least a specified minimum size. 3. The transformer secondary must not contain any overcurrent device whatsoever.

97 Transformers The overcurrent device in the primary of a transformer supplying a fire pump installation. The device is required to be sized to carry the locked-rotor current motor(s) and associated fire pump accessory equipment indefinitely.

98 Power Wiring a) Service and Feeder Conductors. Supply conductors must be physically routed outside buildings and must be installed in accordance with Article Where supply conductors cannot be routed outside buildings, they must be encased in 2 inches or 50 mm of concrete or brick.

99 Power Wiring b) Circuit Conductors. Fire pump supply conductors on the load side of the final disconnecting means and overcurrent device(s) must be kept entirely independent of all other wiring. They can be routed through a building using one of the following methods: 1) Be encased in a minimum 2 inches or 50 mm of concrete 2) Be within an enclosed construction dedicated to the fire pump circuit(s) and having a minimum of a 1-hour fire-resistant rating 3) Be listed electrical circuit protective system with a minimum 1-hour fire rating.

100 (c)(2) BC Conductor Size Fire Pump Motor Branch Circuit Conductor Size From Table (b) Branch circuit conductors to a single fire pump motor must have a rating not less than 125% of the motor FLC as listed in Table or
