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.

12 Principal Members 10 Eligible to Vote on All

2 Members Vote Limited 0 Ballots Not Returned 6 Members voted Affirmative w/Comment on one or more Revision (F. Carpenter, B. Gray, H. Hasan,

J. Jamison, M. O’Boyle, R. Wright, ) 3 Members voted Negative on one or more Revision (F. Carpenter, H. Hasan, M. O’Boyle) 0 Members Abstained on one or more Revision 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.

By adding the words and labeled, it will identify that listed products also need to be labeled. Bothterms listed and labeled are defined in article 100, but are not used consistently throughout theNEC. If taken literally, as defined in Article 100, a product could be listed and not labeled and stillcomply with the NEC when not required to be listed and labeled. This change will help make theNEC a more consistent document for AHJ’s.

Adding a requirement for labeling all Listed equipment is inconsistent with the information provided in theInformational Note associated with the Article 100 definition of “Listed”. Additionally, the Article 100 definition of“Labeled” does not take into account parts that are too small to be labeled, or parts that have a listing markstamped or molded into them.

Hasan, Hakim

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 CMP18 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, CMP18 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.

Outlet Box Hood.

A housing shield intended to fit over a faceplate for flush-mounted wiring devices, or an integralcomponent of an outlet box or of a faceplate for flush-mounted wiring devices. The hood does not serveto complete the electrical enclosure; it reduces the risk of water coming in contact with electricalcomponents within the hood, such as attachment plugs, current taps, surge protective devices, directplug-in transformer units, or wiring devices. It is commonly known as a “bubble cover.”

The NEC does not currently address the differences between the certifications. The work surfaceliquid spillage requirements predate the counter mounted spillage requirements by at least 15-20years and were developed to address a cup of liquid tipped over. The Counter mountedrequirements address the larger quantity of liquid expected in the kitchen or bathroom.

To address this issue the term “Work Surface” is proposed to be added as this is the currentterminology used in the existing standard requirements for the smaller quantity of liquid and“Counter” mounted is the term used in the standards, and the NEC, for the larger quantity of liquid.

It would be suitable to mount a listed Counter type receptacle outlet assembly into the kitchen orbathroom environment but it would not be suitable to mount a Work Surface receptacle outletassembly into a Counter.

Committee Statement

CommitteeStatement:

The text in 406.9(B)(1) requires those outlet box hoods installed for the purpose of providingweatherproof protection to be listed and identified as “extra duty”. Listed equipment often incorporatesreceptacles which are protected by means other than an outlet box hood. For example, the commonconstruction for a Power Outlet (UL 231) locates a receptacle behind a hinged steel cover. This coveris not an outlet box hood, and is not identified as "extra duty". Some confusion has existed over thelack of "extra duty" identification on these types of listed assemblies.

Readability of the Code® regarding Informational Note 2, to preclude continuing misinterpretations.The first sentence regarding "15- and 20-ampere, 125- and 250-volt receptacles" had been clearsince the 2002 NEC® in which it was added that this requirement applies to both nonlocking-typeAND LOCKING-TYPE receptacles in Wet Locations. Please note that this requirement does NOTappear in 406.9(A) for Damp Locations.

When the weather-resistant receptacle requirements were added however to the 2008 NEC® forBOTH Damp Locations [then 406.8(A)] and Wet Locations [then 406.8(B)] that "all 15- and20-ampere, 125- and 250-volt NONLOCKING-TYPE receptacles shall be a listed weather-resistanttype", it was also followed by an Informational Note (then FPN) that indicates "the types ofreceptacles COVERED BY THIS REQUIREMENT are identified as 5-15, 5-20, 6-15, and 6-20 inANSI/NEMA WD 6-2002 ...". While these word presented no conflict for the Damp Locationsrequirement, some have used the unclear editorial placement for Wet Locations to argue that thisInformational Note in 406.9(B) effectively EXCLUDES 15- and 20-ampere, 125- and 250-voltLOCKING-TYPE receptacles from the "while in-use" cover requirements and now the "Extra-Duty"outlet box hood requirements in the first two sentences. (NEMA configuration designations forLOCKING-TYPE would be L5-15, L5-20, L6-15, and L6-20, rather than 5-15, 5-20, 6-15, and 6-20.)These types of false rationalizations come up particularly in OEM installations.

In accordance with NEC® Style Manual 3.1.3, "Informational notes ... shall be located directly afterthe rule they apply to." In accordance with NEC® Style Manual 2.6.1, "Exceptions shall immediatelyfollow the main rule to which they apply." Consequently, Informational Note No 1 and the Exceptionrelate to the main rules of the FIRST TWO SENTENCES regarding "an enclosure that is weatherproofwhether or not the attachment plug cap is inserted" and the associated ""extra-duty" requirement,BUT NOT AFTER the THIRD sentence regarding weather-resistant receptacles. Therefore, theTHIRD SENTENCE and INFORMATIONAL NOTE NO 2 should be relocated AFTERINFORMATIONAL NOTE NO 1 AND THE EXCEPTION, as shown. Also, clarifying words inInformational Note No 2 will further avoid opportunistic misinterpretations.

Committee Statement

CommitteeStatement:

This section should be deleted in its entirety.

This new section sought to correct incompatibilities between certain types of dimmer and certaincord-connected loads. Such incompatibilities are currently dealt with in the listing of specific loadtypes and the listing of specific dimmer types. That is the correct way to prevent unsafeincompatibilities between certain types of loads and certain types of dimmers. To prevent theseincompatibilities by mandating an undefined "non-standard" connector creates more problems than itsolves. The current wording of the section contains a number of major flaws:

1. "Non-standard" is not defined with regard to plug/receptacle combinations. Does this mean alocking-type connector not normally used in a residential application is "non-standard" in such anapplication? Or does it mean that the connector in question must not mate with any existing NEMAtype?

2. The section requires that a plug/receptacle combination be "specifically listed and identified foreach unique combination". Does this mean we need a different unique connector pair for eachcombination of dimmer and dimmable load or load type that is compatible with that dimmer? Clearly,this is preposterous--there are not enough unique listed connectors available to satisfy thisrequirement--there are simply too many combinations of dimmer types (forward phase control,reverse phase control, sine wave--to name just a few) and safely dimmable loads and load types(halogen, fluorescent, magnetic ballasts, electronic transformers, LED drivers etc.).

3. This section sought to correct a specific problem: incompatibility between certain types of LEDunder-cabinet lighting and dimmers. The section wording tried to do this with a broad, sweepingrequirement by requiring a new, undefined type of connector pair unrelated to load vs. dimmerincompatibility. This has two negative results: A) The problem will not get fixed. The same specifiersand installers that ignored the listing requirements of specific dimmers and LED loads will ignore thissection. B) There will be far-reaching unintended consequences in a wide variety of safe applicationsof dimmers with receptacles. This section has already resulted in TIA's on NEC sections 520.45 and530.21(A). The TIA's exempt these sections from section 406.15. There are many other safeapplications of cord-connected loads to dimmers that will be negatively affected by the wording ofsection 406.15 for no good safety reason.


28 of 74 4/17/2015 2:49 PM

Clearly, the creation of this section was an attempt to solve a specific problem associated with anemerging and evolving new technology: LED's. But the wording of section 406.15 will not solve thatproblem, it will simply create additional new problems.

O'Boyle, Michael S.

While I support making the identification of Listed products more convenient to AHJ's and others, I havereservations about accepting FR-5115 without additional clarification on two points: 1) The Article 100 definition ofListed does not include Labeled but the informational note does indicate some organizations use labeling as away to identify listed products. The Article 100 definitions of Listed need revisions to align with this FR. 2) Also,some products are of a size or have material characteristics that prevent physically labeling them. In those caseslisting marks are applied to packaging. Also in the current definition of Labeled, the term “attached” may infer aparticular technique be employed, such as an adhesive label, where listing mark could be applied to products inother ways such as stamping, etching, indelibly printed lettering, molding, etc. Also, there are cases where alaboratories listing mark is allowed to be in an abbreviated form. The Article 100 definition of labeled needs to berevised to clearly reflect these conditions.

Committee Statement

CommitteeStatement:

Some confusion exists regarding the appropriate environmental ratings within the support posts forluminaires. As a raceway for the conductors, Section 300.9 would categorize this location as a “wetlocation”. It is not consistent practice that this be treated as such, especially with respect to thesplices or taps located in handholes within the luminaire support post. The interior of a luminairelisted for wet locations is considered a damp location.

The definition of “Damp Location” in Article 100 describes a location that seems most appropriate forthe inside of a luminaire support post. The result of this categorization would be to require thesplices and taps to be rated for this environment. For a “damp” location, either a “damp” or a “wet”location splice or tap is acceptable. Many “wet location” products exist today, but “damp location”splices and taps are not defined in the UL Standards for these connecting devices.

Committee Statement

CommitteeStatement:

Revisions to Article 411 in the 2014 NEC acknowledged that the provisions of this article shouldapply to class 2 luminaires operating above 30 V (42.4 V pk). This permits luminaires operating up to60 Vdc to be installed without grounding, per NEC 411.6(A). Grounding is not a necessary safetymeasure for products operating from an isolating source, and especially where voltages are withinclass 2 limits where the human body has inherent resistant to the flow of electrical current.

However, the 2014 revisions limited the low voltage power supply to the class 2 power limits of Tables11(A) and 11(B). There is no safety-based reason for this limitation. At 60 Vdc, Table 11(B) limits aclass 2 power supply to a nameplate rating of 100 VA / 1.67 A. This will require many low voltagelighting systems consisting of multiple luminaires to include multiple power supplies. There is nobenefit (i.e., no reduction in either fire or electric shock risk) to compelling the use of multiple powersupplies. The power supply, along with the luminaire(s) and fitting(s), will be evaluated for fire riskregardless of their power/current rating, by means of the listing required under either 411.4(A) or411.4(B). What distinguishes Article 411 from Article 410 is the voltage limitation and isolationrequirement, both of which allow for a different scheme for protection against electric shock injury.


42 of 74 4/17/2015 2:49 PM

These proposed revisions retain the requirement of 411.4(A) that a low voltage bare conductorsystem (aka “trapeze lights”) must be listed as a system. A system listing is necessary for theseproducts because they often rely on special detection circuitry to address the fire risk associated witha conductive material shorting across the exposed conductors.

Because other types of low voltage lighting systems (those that do not include bare conductors) arepermitted to consist of an assembly of listed parts, per 411.4(B), the first sentence of the current411.4(A) should be deleted as overly restrictive and in conflict with 411.4(B). Additionally, thesentence following 411.4(B) duplicates the ‘system’ requirement for bare conductor systems as statedin 411.4(A), so it also should be deleted.

411.6(D) subclauses (1) and (3) refer to wiring methods that are not necessarily restricted to“exposed” locations.

The term “exposed” is appropriate for the bare conductors covered under 411.6(C) but the wiringoptions permitted under 411.6(D) should apply to both exposed and concealed secondary circuitwiring.

By adding the words "and labeled", it will identify that listed products also need to be labeled. Bothterms "listed" and "labeled" are defined in article 100, but are not used consistently throughout theNEC. If taken literally, as defined in Article 100, a product could be listed and not labeled and stillcomply with the NEC when not required to be listed and labeled.This change will help make the NECa more consistent document for AHJ’s

[Formatting note -- revised clause 411.4(B) should consist of only subclauses (1) - (4); the on-line texteditor is showing this as (1) - (5)]

411.4.B ..A requirement that all listed equipment be labeled with the listing organization’s mark of conformityconflicts with the definition of Listed in Article 100, including the Informational Note saying, “Use of the systememployed by the listing organization allows the authority having jurisdiction to identify a listed product.” Thedefinition is not only the NEC definition of Listed, it is an Official NFPA Definition, including the Informational Note(or an Appendix note in many NFPA standards). It is not for CMP18 to decide to override an official definition. Inaddition, it is inappropriate for the NEC Committee to dictate certification practices to listing organizations. Byrequiring that listed equipment display the listing organization’s mark, CMP18 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.

O'Boyle, Michael S.

I support FR-5147 except for the addition of “and labeled” to 411.4(B). While I do support making the identificationof listed products more convenient to AHJ's and others, the addition of “and labeled” requires clarification on twopoints: 1) The Article 100 definition of Listed does not include Labeled but the informational note does indicatesome organizations use labeling as a way to identify listed products. The Article 100 definitions of Listed needrevisions to align with this FR. 2) Also, some products are of a size or have material characteristics that preventphysically labeling them. In those cases listing marks are applied to packaging. Also in the current definition ofLabeled, the term “attached” may infer a particular technique be employed, such as an adhesive label, wherelisting mark could be applied to products in other ways such as stamping, etching, indelibly printed lettering,molding, etc. Also, there are cases where a laboratories listing mark is allowed to be in an abbreviated form. TheArticle 100 definition of labeled needs to be revised to clearly reflect these conditions.

Wright, Randall K.

I feel the removal of class 2 makes these installations less safe. The grounding exception was only intended forclass 2 and should not now be exempted.

CommitteeStatement:

The panel understands the scope is under the purview of the correlating committee and requeststhat they consider our proposed change. Retrofit kits are now required to be listed, marked andinstalled in a listed sign. Definitions in the glossary have been added during the last cycle whichdefines what a kit comprises. Adding to the scope of this article, the retrofit kits shall be configuredspecifically for the exact sign in which the system is being replaced. Because kits are listed forspecific signs, the Authority Having Jurisdiction will need to know what is being changed in a listedsign.

Committee Statement

CommitteeStatement:

A PV system is defined in Article 100 and installation rules are in 690. Signs are a specialapplication of PV equipment that is described and covered by UL Standard 48 4.4.4.12. Thedefinition provides the basis of a new Article 600 Section with field wiring rules for installation andelectrically safe usage. The panel has added the word “powered” for clarity.

Since “photovoltaic” refers to the system furnishing power to operate the sign, and not to aparticular type of sign, the original definition is flawed. Signs powered by a PV system will requirespecial installation instructions and a new section is added in 600.34, in addition to the applicationof Article 690.

By adding the words "and labeled", it will identify that listed products also need to be labeled. Bothterms "listed" and "labeled" are defined in article 100, but are not used consistently throughout theNEC. If taken literally, as defined in Article 100, a product could be listed and not labeled and stillcomply with the NEC when not required to be listed and labeled. This change will help make theNEC a more consistent document for AHJ’s.

Since “photovoltaic” refers to the system furnishing power to operate the sign, and not to a particulartype of sign, the original definition is flawed.

NEMA agrees with this first revision with the exception of the addition of the words “and labeled”. Adding arequirement for labeling all Listed equipment is inconsistent with the information provided in the Informational Noteassociated with the Article 100 definition of “Listed”. Additionally, the Article 100 definition of “Labeled” does nottake into account parts that are too small to be labeled, or parts that have a listing mark stamped or molded intothem.

Committee Statement

CommitteeStatement:

Electric signs that have been retrofitted need to be marked for the authority having jurisdiction (AHJ)to inspect the retrofit based on the installation instructions, which need to be provided as part of thekits listing. The installer and/or serving agent needs to be notified the sign has a retrofitted lightingsystem as a safety concern. The service agent shall make sure the new correct parts are replacedand not replaced with the original parts. The warning label should be optional based on thereplacement products. The label is important because replacing a tubular light-emitting diode lampwith a regular lamp may have explosive events if the sockets are energized.

The panel has reworded #3 into more positive language based on the intent. (an informational notecould be required)

The section (A) should remain and add the balance as (B) and renumber accordingly.

Committee Statement

CommitteeStatement:

This permits energized circuit conductors in a Chapter 3 raceway to be run through the sign body toa sub-panel or sub-panels located within the sign body. A typical example is a sign body or enclosurethat is supplied from feeders originating at the premise’s service equipment. Due to the size orlocation of the sign, to facilitate servicing of the sign, it is desirable/necessary to control multiplelighting loads at or from within the sign body or enclosure.

This is one of the issues that emerged from CMP 18 during the 2014 ROP and ROC stages regarding600.6(A)(1). Concern was expressed about the rule’s impact on large signs incorporating internalpanel boards supplying enclosures within sign bodies attached to multi-story structures thatarchitecturally complement the signage design. Live feeders and/or branch circuits enter and passthrough these sign bodies or enclosures in Chapter 3 raceways and terminate at internal panelboards. The multi-story Aria sign is an example. Exhibit # 3 600.6(A)(1) Exception No. 3

These panel boards are located on different levels (stories) within the sign bodies or enclosures. It isimpractical to de-energize the entire sign, much the same as it is with a multi-story building. Servicepersonnel use the circuit breakers in the sub-panel(s) as a disconnecting means for branch circuitson the level (floor) where they are working.

The Chapter 3 raceway(s) that encloses the live service conductors, feeders or branch circuitspassing through the sign body or enclosure is accessible to service personnel. Electrical safetydictates that these raceways be identified to prevent accidental or deliberate penetration. OSHA1910.335(b)(1) requires the use of safety signs, safety symbols or accident-prevention tags to warnabout potential electrical hazards. Markings with similar warnings are found throughout the Code.[e.g. Article 692.17]

Equally as important, in the event of an emergency requiring de-energizing the live feeders or branchcircuits passing through the sign body, the location of the disconnecting means, which is out of theline of sight and at a location other than the sign, must be known and accessible to service personnelor emergency responders. Providing a field-applied label with the location of the disconnecting meanswill contribute to electrical safety for service personnel.

The intent is not to disconnect the grounding conductors as implied in 600.6(A)(1).

The question that arises is if we call this sign a “structure” are there other articles that may apply?Article 225, Part II for Buildings or Other Structures Supplied by a Feeder(s) or Branch Circuit(s). AlsoSection 250.32 could apply for Buildings or Structures Supplied by a Feeder(s) or Branch Circuit(s).Another example of items that may need to be addresses are, Spread of Fire or Products ofCombustion, Plenums, Electrical Classification of Data Circuits, Fire Alarm Equipment,Communications Equipment, Storage Batteries, Surge-Protective Devices (SPDs), Lighting, PowerDistribution Wiring and Wiring Protection, Service Equipment, Distribution Transformers, EmergencyLighting and Emergency Lighting Circuits, Entrance to and Egress from Working Space. A good


56 of 74 4/17/2015 2:49 PM

example of these is the organization of Article 646.

Also upon further research with several Building Officials, they determined that this sign structure ormonument sign would be required to obtain a building permit separate from the sign permit. If this isthe case and this is a separate structure then the requirements of 600.6 are already meet.

CommitteeStatement:

By adding the word "labeled", it will identify that listed products also need to be labeled. Both terms"listed" and "labeled" are defined in article 100, but are not used consistently throughout the NEC. Iftaken literally, as defined in Article 100, a product could be listed and not labeled and still complywith the NEC when not required to be listed and labeled.
