TO: NEC® Code-Making Panel 15

FROM: Kimberly Shea, Project Administrator

DATE: April 17, 2015

SUBJECT: NEC First Draft TC FINAL Ballot Results (A2016)

According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot.

14 Members Eligible to Vote on All 5 Members Vote Limited 2 Ballots Not Returned (K. Gilbert, K. Jones)

9 Members Voted Affirmative with Comment on one or more Revisions (C. Beebe, D. Dagenais, J. DuPriest, M. Hefter, E. Kramer, S. Lipster, M. Skinner, L. Todd, K. Vannice)

3 Members Voted Negative on one or more Revisions (C. Beebe, B. Rock, L. Todd) 0 Abstentions on one or more Revisions The attached report shows the number of affirmative, negative, and abstaining votes as well as the explanation of the vote for each first revision.

There are two criteria necessary for each first revision to pass ballot: (1) simple majority and (2) affirmative 2/3 vote. The mock examples below show how the calculations are determined.

(1) Example for Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative votes are required to pass ballot. (Sample calculation: 20 members eligible to vote ÷ 2 = 10 + 1 = 11)

(2) Example for Affirmative 2/3: Assuming there are 20 vote eligible committee members and 1 member did not

return their ballot and 2 members abstained, the number of affirmative votes required would be 12. (Sample calculation: 20 members eligble to vote – 1 not returned – 2 abstentions = 17 x 0.66 = 11.22 = 12 )

As always please feel free to contact me if you have any questions.

Committee Statement

CommitteeStatement:

The term Limited Care Facility was removed from 2015 edition of NFPA 99 FundamentalsCommittee. This term is referenced in the 2014 edition of the NEC in sections: 517.2 Definition,517.10(B)(2), 517.18 (A), 517.18 (A) Exception 1, 517.25, 517.40, 517.40 (A), 517.40 (A) Exception,517.40 (B), 517.40 (C), 517.40 (C) Informational Note, 517.41 (A), 517.44 (B) Exception 2, Index p887 Nursing Homes and Limited Care Facilities, Index p 891 Limited Care Facilities of the 2014NEC.

The CMP term should remain as a definition in 517.2 for clarity. As stated, defining this occupancywill be useful for inspectors, installers, and other users of the code trying to determine whatinstallation practices are necessary for required wiring methods and approval of equipment. Theterm is no longer used of design considerations.

Further, use of this term and its previsions for identification are included in other definitions andseveral sections of 517 as it addresses installation in healthcare facilities. With the contiguousnature of most healthcare occupancies the classification of occupancy is determined by the use ofthe space as defined elsewhere in 517.2.

Beebe, Chad E.

The inclusion of the category numbers is correct - but the terms, basic, general, critical and support need to beremoved. The NFPA 99 committee intentionally removed these terms to avoid any confusion. By leaving them inhere it will be confusing for inspectors when they try to apply the section based on a pre-determined name vs. therisk assessment performed by the gov. body to determine the appropriate category.

Dagenais, David A.

I support the concept of matching the categories used in NFPA 99 however by using the terms basic, general,and critical it implies that those spaces must be the attached category. Those terms should be remove so thecategories can stand alone.

The National Electrical Code is an installation code as stated in 90.2. Article 517 details the special installationrequirements necessary in health care facilities, as stated in 517.2. The NEC and Article 517 is an installationcode not a design or performance code; this fact has been reinforced by several recent Standards Councildecisions. Therefore logic dictates that if 517 is an installation code, requirements for the design and performanceelements of a health care electrical systems should be removed from 517 entirely and code users should bedirected to the appropriate NFPA design and performance documents in a 517.2 informational note.

517.16 Use of Isolated Ground Receptacles.

(A)

An isolated ground grounding receptacle shall not be installed within a patient care vicinity.[99:6.3.2.2.7.1(B)]

(B)

Isolated grounding receptacle(s) used outside of a patient care vicinity shall not defeat the purposes ofthe safety features of the grounding systems detailed in 517.13 .

(1)

Isolated grounding receptacles installed in branch circuits for patient care spaces shall be connected toan insulated equipment grounding conductor in accordance with 250.146(D) in addition to the twoequipment grounding conductor paths required in 517.13(A) and (B).

(2)

The equipment grounding conductor installed for isolated grounding receptacles in patient care areasshall be clearly identified using green insulation with one or more yellow stripes along its entire length.

Informational Note No. 1: This type of installation is typically used where a reduction of electricalnoise (electromagnetic interference) is necessary, and parallel grounding paths are to beavoided.

Informational Note No. 2: Care should be taken in specifying a system containing isolatedground receptacles, because the grounding impedance is controlled only by the grounding wiresand does not benefit from any conduit or building structure in parallel with the grounding path.[ 99: A.6.3.2.2.7.1 ]

This change adds clarity to the code and provides requirements for branch circuits serving areaswhere isolated equipment grounding conductor and IG receptacles are specified.

Changing the language of this section will reduce confusion that exists regarding the number ofequipment grounding conductors that must be installed for isolated grounding receptacles installedoutside the patient care vicinity in a patient care spaces. The color designation of green with one ofmore yellow stripes will provide a color used as an industry standard for IG grounds.

Although the term "grounding" may be accurate - I don't think the term "ground" is inaccurate. In this case, since itis extracted text it would be better to keep the terms, and therefor the extraction the same. There is no value tomaking that editorial change as it will only lead to confusion as users try to justify the difference by inferring thereason behind the difference.

Dagenais, David A.

I agree with extracting the text from NFPA 99 however it should be extracted exactly, the term “Ground” should beused.

PI 3067 was revised by the Panel to remove performance requirements.

Public Input now correlates with 2015 NFPA 99 language as general care areas are now considered

general care (Category 2) spaces. All references to Patient Care Spaces have inserted new 2015NFPA 99 reference to Category designation in parenthesis. Editorial change is made to correctsection reference.

Public Input 4499 sought to delete a perceived redundant requirement; however, panel does notagree that “correlation conflicts” exist or that removing this statement would somehow improveclarity. The information describing the critical branch circuit should remain in this section.

Public Input 4493: This change would allow the receptacles in patient bed location to be connectedto the equipment branch of the essential electrical system which by design does not provide a levelof reliability required for these important lifesaving circuits. The Panel does not see any correlationconflicts between Part III of 517 or NFPA 99. Removing this statement would not improve clarity tothe code.

Public Input 4516 seeks to insert redundant reference and does not add clarity to code.

NOTE TO CORRELATING COMMITTEE AND NFPA STAFF: For Code usability, CMP-15recommends the transition from critical/general/basic care space to numbered Category Spaceterms be handled like the transition from “lighting fixture” to “luminaire” over a few Code cycles, withboth old and new terms used parenthetically during the transition.

(D) Patient Care Vicinity Grounding and Bonding (Optional).

A patient care vicinity shall be permitted to have a patient equipment grounding point. The patientequipment grounding point, where supplied, shall be permitted to contain one or more listed groundingand bonding jacks. An equipment bonding jumper not smaller than 10 AWG shall be used to connect thegrounding terminal of all grounding-type receptacles to the patient equipment grounding point. Thebonding conductor shall be permitted to be arranged centrically or looped as convenient.

Informational Note: Where there is no patient equipment grounding point, it is important that thedistance between the reference grounding point and the patient care vicinity be as short aspossible to minimize any potential differences.

(E) Equipment Grounding and Bonding.

Where a grounded electrical distribution system is used and metal feeder raceway or Type MC or MIcable that qualifies as an equipment grounding conductor in accordance with 250.118 is installed,grounding of enclosures and equipment, such as panelboards, switchboards, and switchgear, shall beensured by one of the following bonding means at each termination or junction point of the metal racewayor Type MC or MI cable:

(1) A grounding bushing and a continuous copper bonding jumper, sized in accordance with 250.122,with the bonding jumper connected to the junction enclosure or the ground bus of the panel

(2) Connection of feeder raceways or Type MC or MI cable to threaded hubs or bosses on terminatingenclosures

(3) Other approved devices such as bonding-type locknuts or bushings. Standard locknuts shall not beused for bonding.

(F) Additional Protective Techniques in Critical Care (Category 1) Spaces (Optional).

Isolated power systems shall be permitted to be used for critical care (Category 1) spaces, and, if used,the isolated power system equipment shall be listed as isolated power equipment. The isolated powersystem shall be designed and installed in accordance with 517.160.

Where an isolated ungrounded power source is used and limits the first-fault current to a low magnitude,the equipment grounding conductor associated with the secondary circuit shall be permitted to be runoutside of the enclosure of the power conductors in the same circuit.

Informational Note: Although it is permitted to run the grounding conductor outside of the conduit, itis safer to run it with the power conductors to provide better protection in case of a second groundfault.

(H) Special-Purpose Receptacle Grounding.

The equipment grounding conductor for special-purpose receptacles, such as the operation of mobileX-ray equipment, shall be extended to the reference grounding points of branch circuits for all locationslikely to be served from such receptacles. Where such a circuit is served from an isolated ungroundedsystem, the grounding conductor shall not be required to be run with the power conductors; however, theequipment grounding terminal of the special-purpose receptacle shall be connected to the referencegrounding point.

The National Electrical Code is an installation code as stated in 90.2. Article 517 details the special installationrequirements necessary in health care facilities, as stated in 517.2. The NEC and Article 517 is an installationcode not a design or performance code; this fact has been reinforced by several recent Standards Council


78 of 176 4/16/2015 2:32 PM

decisions. Therefore logic dictates that if 517 is an installation code, requirements for the design and performanceelements of a health care electrical systems should be removed from 517 entirely and code users should bedirected to the appropriate NFPA design and performance documents in a 517.2 informational note.

517.30 Sources of Power.

(A) Two Independent Power Sources of Power .

Essential electrical systems shall have a minimum of the following two independent sources of power: anormal source generally supplying the entire electrical system and one or more alternate source( s) foruse when the normal source is interrupted. [99:6.4.1.1.4]

(B) Alternate Source Types of Power Sources .

The alternate source of power shall be one of the following:

(0) Generator(s) driven by some form of prime mover(s) and located on the premises

(0) Another generating unit(s) where the normal source consists of a generating unit(s) located on thepremises

(0) An external utility service when the normal source consists of a generating unit(s) located on thepremises

(0) A battery system located on the premises [ 99: 6.4.1.2]

(1)

Where the normal source consists of generating units on the premises, the alternate source shall beeither another generating set or an external utility service. [ 99: 6.4.1.1.5]

(2) Fuel Cell Systems.

Fuel cell systems shall be permitted to serve as the alternate source for all or part of an essentialelectrical system, provided the following conditions apply:

(1) N 1 units shall be provided where N units have sufficient capacity to supply the demand loads ofthe portion of the system served.

(2) System shall be able to assume loads within 10 seconds of loss of normal power source.

(3) System shall have a continuing source of fuel supply, together with sufficient on-site fuel storagefor the essential system type.

(4) A connection shall be provided for a portable diesel generator to supply life safety and criticalportions of the distribution system. [ 99: 6.4.1.1.7(1) through (5)]

(5) Fuel cell systems shall be listed and labeled for emergency system use.

(C) Location of Essential Electrical System Components.

Careful consideration shall be given to the location of the spaces housing the components of the essentialelectrical system Essential electrical system components shall be located to minimize interruptionscaused by natural forces common to the area (e.g., storms, floods, earthquakes, or hazards created byadjoining structures or activities). Consideration Installations of electrical services shall also begiven located to the reduce possible interruption of normal electrical services resulting from similarcauses as well as possible disruption of normal electrical service due to internal wiring and equipmentfailures. Consideration Feeders shall be given located to the provide physical separation of the mainfeeders of the alternate source and from the main feeders of the normal electrical source to preventpossible simultaneous interruption.

Informational Note: Facilities in which the normal source of power is supplied by two or moreseparate central station-fed services experience greater than normal electrical service reliabilitythan those with only a single feed. Such a dual source of normal power consists of two or moreelectrical services fed from separate generator sets or a utility distribution network that has multiplepower input sources and is arranged to provide mechanical and electrical separation so that a faultbetween the facility and the generating sources is not likely to cause an interruption of more thanone of the facility service feeders.

I agree with extracting the text from NFPA 99 however it should be extracted exactly and should not addadditional requirements like listed and labeled.

DuPriest, Joe L.


Lipster, Stephen M.


Negative with Comment

Beebe, Chad E.

The extraction reference is incorrect. NFPA 99 does not have parens 1-5. The reference should be to 6.4.1.1.7.1,6.4.1.1.7.2, 6.4.1.1.7.3, 6.4.1.1.7.4 and 6.4.1.1.7.5. A reference to NFPA 853 needs to be added and thereference to listed and labeled needs to be deleted.

517.41 Required Power Sources of Power .

(A) Two Independent Power Sources of Power .

Essential electrical systems shall have a minimum of the following two independent sources of power: anormal source generally supplying the entire electrical system and one or more alternate sources for usewhen the normal source is interrupted. [99:6.5.1 6.4.1.1.4 ]

(B) Alternate Source of Power Types of Power Sources. .

The alternate source of power shall be a generator(s) driven by some form of prime mover(s) and locatedon the premises. Where the normal source consists of generating units on the premises, the alternatesource shall be either another generator generating set or an external utility service. [ 99: 6.4.1.1.5]

Exception No. 2: Nursing homes or limited care facilities meeting the requirement of 517.40(A) andother health care facilities meeting the requirement of 517.45 shall be permitted to use a batterysystem or self-contained battery integral with the equipment.

(C) Location of Essential Electrical System Components.

Careful consideration shall be given to the location of the spaces housing the components of the essentialelectrical system Essential electrical systems shall be located to minimize interruptions caused by naturalforces common to the area (e.g., storms, floods, earthquakes, or hazards created by adjoining structuresor activities). Consideration Installations of electrical services shall also be given located to the reducepossible interruption of normal electrical services resulting from similar causes as well as possibledisruption of normal electrical service due to internal wiring and equipment failures. Feeders shall belocated to give physical separation of the feeders of the alternate source and from the feeders of thenormal electrical source to prevent possible simultaneous interruption.

Informational Note: Facilities in which the normal source of power is supplied by two or moreseparate central station-fed services experience greater than normal electrical service reliabilitythan those with only a single feed. Such a dual source of normal power consists of two or moreelectrical services fed from separate generator sets or a utility distribution network that has multiplepower input sources and is arranged to provide mechanical and electrical separation so that a faultbetween the facility and the generating sources will not likely cause an interruption of more thanone of the facility service feeders.

Adding "and listed" clarifies to both users, designers and enforcers the requirements for medical equipment.


Todd, Lawrence E.

A requirement that all listed equipment be labeled with the listing organization’s mark of conformity conflicts withthe definition of Listed in Article 100, including the Informational Note saying, “Use of the system employed by thelisting organization allows the authority having jurisdiction to identify a listed product.” The definition is not only theNEC definition of Listed, it is an Official NFPA Definition, including the Informational Note (or an Appendix note inmany NFPA standards). It is not for CMP15 to decide to override an official definition. In addition, it isinappropriate for the NEC Committee to dictate certification practices to listing organizations. By requiring thatlisted equipment display the listing organization’s mark, CMP 15 would be dictating the business practices of thevarious listing organizations without a clear statement of need, against the advice contained in the InformationalNote to the definition.

Revised language is confusing. While there is no table 520.23, not including the word "section" in front of itcauses one to look for such a table. Either put the word Section in front of 210.23 or change the order of thereferences: "210.23 and Table 210.21(B) shall not apply ..."

Kramer, Edwin S.

Original had “... and section 210.23”. Staff removed “section”. So it now reads Table 210.21(B)(2) and 210.23.

My records show "Table 210.21(B)(2) and section 210.23 shall not apply." Somehow the word "section"disappeared. So now it effectively reads "Table 210.21(B)(2) and Table 210.23 shall not apply." Table 210.23doesn't exist. The word "section" should be put back or re-order the words "210.23 and Table 210.21(B)(2) shallnot apply."

*Ampacity shown is the ampacity for multiconductor cords and cables where only three copper conductorsare current-carrying as described in 400.5. If the number of current-carrying conductors in a cord or cableexceeds three and the load diversity factor is a minimum of 50 percent or less , the ampacity of eachconductor shall be reduced as shown in the following table:

Number of Conductors Percent of Ampacity

43 and above 50

Note: Ultimate insulation temperature. In no case shall conductors be associated together in such a waywith respect to the kind of circuit, the wiring method used, or the number of conductors such that thetemperature limit of the conductors is exceeded.

A neutral conductor that carries only the unbalanced current from other conductors of the same circuitneed not be considered as a current-carrying conductor.

In a 3-wire circuit consisting of two phase 2-phase conductors and the neutral conductor of a 4-wire,3-phase, wye-connected system, the neutral conductor carries approximately the same current as theline-to-neutral currents of the other conductors and shall be considered to be a current-carrying conductor.

On a 4-wire, 3-phase wye circuit where the major portion of the load consists of nonlinear loads, thereare harmonic currents in the neutral conductor. Therefore, the neutral conductor shall be considered to bea current-carrying conductor.

Informational Note: For the purposes of Table 520.44(C)(2) , load diversity is the percentage ofthe total current of all simultaneously energized circuits fed by the cable to the sum of the ampacityratings of all circuits in that cable.

Hefter, Mitchell K.

Our original intent was to add a title to the second section or break Table 520.44 into two tables for clarity got lostin editing or the (needed) emphasis on defining load diversity (the added Informational Note). -.....- It would bebetter if the Table was broken into two - 520.44(C)(2)(1) for the top half and 520.44(C)(2)(2) for the bottom half -


128 of 176 4/16/2015 2:32 PM

and the right hand column of the second part (table) read 'Percent of Value in Table 520.44(C)(2)(1).' This followsthe style of Tables 400.5. Some tweaks beyond correcting the reference to Table 520.44 to 520.44(C)(2) may berequired. -.....- The informational Note added clarifies what diversity is. Stating "... the load diversity is a minimumof 50% or less, ..." between the two table sections seems redundant. Remove "a minimum of" from the sentence.-.....- Edits to the next to last paragraph changed the reference of two different phases of a 3-Phase, 4-wire circuitto 2-phase ("In a 3-wire circuit consisting of 2-phase conductors and the neutral ..."). -.....- Next to last paragraphis wrong - we are only talking about two of the phases (e.g., B & C) of the 3-Phase (A, B, C) circuit. I do not recallthis change was discussed.

It was properly referenced to section 520.44(C)(2) but all the table references inthat section were not changed 2) The proposal asked to add a title to the adjustment table for emphasis. Also theproposal asked that “Value in Table 520.44” [now 520.44 (C)(2)] be added to “Percent of Ampacity” for emphasiswhich was not done.

Skinner, Michael D.

1. No numbering change was discussed for Table 520.44, yet it has been changed to 520.44(C)(2). Was thisrequired by the addition of a new table number to the Ampacity Adjustment section of table 520.44? 2. Theampacity adjustment table within table 520.44 was to have been given a number and retitled: “Ampacityadjustment factors for more than three current-carrying conductors in a cord or cable where load diversity is 50%or less”. In addition, the right-hand column of this table was to have been retitled “Percent of Ampacity Value inTable 520.44”. None of these changes appear in the First Revision Report. Note: In FR 4227 for section 520.68(b),the Ampacity Adjustment Table for Table 520.44(C)(2) is referred to as table 520.44(3)(B). Presumably this wasthe new number assigned to this table, although it does not seem to make sense as there is no such section in520.44.

Vannice, Kenneth E.

The revision was fine until it was edited. Now it needs to be re-edited. Furthermore this document is not inalignment with the draft. The unacceptable edits are noted. 1. The table was re-numbered and its reference iscorrect. The references to this table in the 520.44(C)(3)text have not been noted in this document but have beenmade in the draft. 2. In the *Ampacity note "or less" was added. How can a value be less than a minimum? 3. Atitle was added to the diversity table and the title of the columns were modified to add emphasis. This was thepoint of the proposal. These are all missing and need to be put back. 4. In the second to last paragraph "twophase conductors" was changed to "2-phase conductors". Two phases of 3-phase is not 2-phase.

Committee Statement

CommitteeStatement:

In Article 520 venues, receptacles may be connected to dimmers, relays, or directly to anovercurrent protective device without control, depending on the needs of a particular production. In amodern theatrical lighting system, the configuration of a receptacle (dimmed, switched, or constantpower) may even be determined by the configuration settings of the control system

feeding the receptacle. In addition, a theatre uses many different types of “standard” NEMA orANSI/PLASA configuration receptacles in the same facility. These might include stage pinreceptacles (ANSI/PLASA E1.24 and reference by UL 498), parallel blade receptacles, or twist-lockreceptacles. Any or all of these configuration types may be controlled by a dimmer.

Personnel operating a theatre are trained in the management of dimmed, switched, andconstant-power circuits and receptacles. This has been the practice for many years, and there is norecord of loss to warrant applying the general-purpose restriction of section 406.15 to the SpecialOccupancies of Article 520. Trained personnel in Article 520 venues are aware of these factors andaddress them in their regular duties.

Without the wording of this First Revision , new section 406.15 will have a material and costly effecton construction, renovation, and operating practice in all article 520 venues that is not warranted byany documented safety problem.

Provides an exception to 406.15 in a controlled environment.


Rock, Brian E.

Consistent with NEMA’s position on 2014 NEC® TIA Log #1151, NEMA opposes this First Revision FR4211based upon the lack of correlation between NEC® 520.45 as revised by FR4211 and existing requirements ofNEC® 406.4(F), 110.3(B), 90.7, and 406.15. The intent of the submitter is to use theatrical dimmers to controlcord-and-plug-connected lighting loads connected to general-use-configuration receptacles. Dimmers alter thewaveform of alternating current. NEC® 406.4(F) permits facility reassignment of general-use receptacleconfigurations based upon voltage, frequency and types of current (e.g., ac or dc) but NOT based upon alteredwaveform. Such chopping alteration of the ac waveform could result in overheating the windings of motor,transformer or ballast loads plugged into these general-use configuration receptacles. As such, this is contrary tothe listings [NEC® 90.7] and the markings and installation instructions [NEC® 110.3(B)] of these receptacles andtherefore represents a correlation issue. To preclude incorrect equipment being connected to general-use-configuration receptacles, NEMA strongly urges adoption of cautionary warnings in NEC® 520.45, to beapplied adjacent to those receptacles by the installer (similar to the cautionary marking required by the ULstandard for dimmers): “CAUTION – Risk of Overheating. Do NOT connect motor-operated equipment,fluorescent lighting fixtures (luminaires), or transformer-supplied equipment to this receptacle.” NEMA also urgesthe Correlating Committee to convene a Task Group of CMP-18 (receptacles), CMP-9 (dimmers), and CMP-15(theaters) to reconcile the lack of correlation.

Section 520.53 has long had two problems: (A) It contained antiquated construction requirementsthat were aimed at shop-built, unlisted resistance boards, and (B) It mixed requirements for portablestage switchboards and supply conductors into a single section. This First Revision removesantiquated construction references, adds a listing requirement, and breaks out supply conductorrequirements into new section 520.54. The listing requirement is needed since modern portableswitchboards are complex and cannot be properly evaluated without a listing.

The creation of new section 520.54 is intended to improve readability. Removal of reference to400.10 correlates with the exception added to 400.10.

Updates code section to make allowances for more complex equipment and for Portable switchboards which hasnow been defined in 520.

Todd, Lawrence E.

Agree with all except the addition of the words "and labeled" In the first sentence of 520.53. The reason toremove the words is: A requirement that all listed equipment be labeled with the listing organization’s mark ofconformity conflicts with the definition of Listed in Article 100, including the Informational Note saying, “Use of thesystem employed by the listing organization allows the authority having jurisdiction to identify a listed product.”The definition is not only the NEC definition of Listed, it is an Official NFPA Definition, including the InformationalNote (or an Appendix note in many NFPA standards). It is not for CMP15 to decide to override an official definition.In addition, it is inappropriate for the NEC Committee to dictate certification practices to listing organizations. Byrequiring that listed equipment display the listing organization’s mark, CMP 15 would be dictating the businesspractices of the various listing organizations without a clear statement of need, against the advice contained in theInformational Note to the definition.

Vannice, Kenneth E.

The removal of references to 400.7/400.10/400.14 is based on the assumption that they refer to Pull at Joints andTerminals and its exception. This point has been confused by the re-numbering of Article 400 sections.

(3) Luminaire Supply Cords.

Listed hard usage supply cords shall be permitted to supply luminaires when all of the following conditionsare met:

(1) The supply cord is not longer than 1.0 2.0 m (3.3 6.6 ft).

(2) The supply cord is attached at one end to the luminaire or a luminaire-specific listed connector thatmates with a panel-mounted inlet on the body of the luminaire.

(3) The supply cord is protected by an overcurrent protective device of not more than 20 amperes.

(4) The luminaire is listed.

(5) The supply cord is not subject to physical damage.

Committee Statement

CommitteeStatement:

For 520.68(A)(3): With the transition of the entertainment industry to LED luminaires, preferredmethods of power distribution are also changing. The number of luminaires on each branch circuit isincreasing, and the built-in daisy-chaining feature of LED luminaires is being used more frequently. Inthis arrangement, the 1m (3.3') length limit on hard-usage luminaire power cords has proven to betoo short for practical use, requiring the addition of many short portable extension cords betweenluminaires. This arrangement decreases reliability and increases system setup time andtroubleshooting.

Use of hard-usage cables in Breakout Assemblies in lengths up to 6m (20') has been proven safe ina restricted application in in article 520 occupancies over many years. The proposed increase inallowable length of hard-usage luminaire supply cords to 2m (6.6') will greatly increase system utilityin the changing LED environment, without compromising safety.

Committee Statement

CommitteeStatement:

In Article 530 venues, receptacles may be connected to dimmers, relays, or directly to anovercurrent protective device without control, depending on the needs of a particular production. In amodern lighting system, the configuration of a receptacle (dimmed, switched, or constant power) mayeven be determined by the configuration settings of the control system feeding the receptacle. Inaddition, a studio uses many different types of “standard” NEMA or ANSI/PLASA configurationreceptacles in the same facility, these might include stage pin receptacles (ANSI/PLASA E1.24 andreference by UL 498), parallel blade receptacles, or locking type

receptacles. Any or all of these configuration types may be controlled by a dimmer.

Personnel operating a studio are trained in the management of dimmed, switched, andconstant-power circuits and receptacles. This has been the practice for many years, and there is norecord of loss to warrant applying the general-purpose restriction of section 406.15 to the SpecialOccupancies of Article 530. Trained personnel in Article 530 venues are aware of these factors andaddress them in their regular duties.

Without the wording of this revision, new section 406.15 will have a material and costly effect onconstruction, renovation, and operating practice in all article 530 venues that is not warranted

by any documented safety problem.
