Same "only" comment as SR 7765 610.2

Joiner, Mark S.

I fully support the committee's statement "The panel appeals to the correlating committee to put all definitions inArticle 100 and assign code making panel responsibility to each definition." The end user should have the ability tohave a "one stop shop" when researching definitions but the expertise of each subcommittee should prevail whenestablishing the verbiage of each definition.

Reighard, Karl

Holmes, Jeffrey L.

This is not needed .The Style Manual already states that definitions appearing in xxx.2 only apply to that Article.Moving all definitions to Article 100 would make those definitions apply globally to all Articles and create moreconfusion.

Cline, Scott

I'll make this argument only once, because it will be the same for all instances of the use of the term. Myunderstanding of our directed purpose in adding text to state limits of use for our definitions, was to make clearwhere in the Code the defined term was to be applied. The phrase "This definition shall apply within this articleand throughout the code." is unambiguous, imparting clear meaning. Indeed, if this is the phrase-form (in singularand plural) to be accepted for use throughout the NEC, then I believe that its existence accentuates theuselessness of adding the term "only" in our other phrase form. The phrase-form "This definition shall apply withinthis article." is also unambiguous, imparting clear meaning. Adding the term "only" within it creates anunnecessary and unintended ambiguity. "This definition shall apply only within this article." states in literal butambiguous logic that the given definition is not allowed to be used anywhere else in the NEC. Why add it? If wesimply do not use the term "only" then our meaning is still fully communicated, and cyclic review for createdconflicts is not necessary. My hope is that the CC determines that the phrase forms : "This definition shall applywithin this article and throughout the code." "This definition shall apply within this article." (in singular and plural asappropriate) are the approved forms for standardized use for the NEC. I vote in agreement for the use ofstandardized phrases, but protest the inclusion of the term"only" within them.

Due to a rare confluence of chance, it is possible that the 620.21(A)(1) parenthetic subitems (d) and (e) mightmistakenly be interpreted as part of the 621.21(A)(1)(c)(4) list of items. The intent is that only a. b. or c. areincluded in the "one of the following" list.

Reighard, Karl

The electric utility industry recognizes the need to provide a minimum level of safety in electrical systems, andthat the overall scope of the NEC as per Article 90 permits it to regulate premise wiring along with conductors andconnection assemblies used to enable the transfer of electric power into and out of premise wiring systems, in thiscase to or from an EV. Unfortunately this language does not go far enough to provide a limit as to how far into theelectrical system within the EV itself that word "equipment" will allow the NEC to be applied. As stated now,"equipment" can include everything from the connector attaching the cable outside of the EV clear through the EVsystem to its alternator or battery pack. This is clearly beyond the limit provided by the overall scope of the NECcontained in Article 90. In order that sufficient protections remain in place until this lapse is corrected, the electricutility industry (as represented through the EEI) is voting in favor of the current change. It is our hope that duringthe upcoming code cycle the scope of this article is brought into alignment with the overall scope of the NEC perArticle 90 such that a clear limit to the applicability of this code is restored.



There are objections to dropping the phrase “external to an electric vehicle” for the scope of this article. Droppingthis phrase and attempting to establish requirements for on-vehicle components puts the scope of the article indirect conflict with the scope of NFPA-70 which specifically excludes on-vehicle equipment. This is likely to causeissues in the field, especially with AHJs that will have no mechanisms in place to enforce any on-vehiclerequirements. Also, as was noted at the Second Draft meeting, there is a strong potential for NFPA-70requirements, now or in the future, to be in direct conflict with requirements established by either the NationalHighway Traffic Administration or by industry organizations such as SAE International. Since the NFPA-70 scopeis clear on its exclusion of automotive vehicles, it is likely that many manufacturers/suppliers of on-vehicleequipment, especially those that are not intimately involved in the NFPA revision process, may not even recognizethat there are requirements intended for their products contained in the NFPA-70 standard. Another major issuearises since different states and locations adopt different versions of the Code, and this could result in situationswhere a particular vehicle model would fulfill the NEC requirements in its own State but not in adjacent States. Atthis point it is logical to drop the on-vehicle requirements until there is appropriate coordination with theorganizations chartered to define on-vehicle requirements. SAE International has offered to support harmonizedrequirements, and hence a joint NFPA-SAE team should be formed to 1) review the existing requirements both onand off a vehicle and 2) if needed, establish additional requirements to fill any gaps in the safety coverage of thecomplete system. This joint working-group plan will insure complete and consistent requirements while providingan appropriate separation of on and off vehicle requirements. By maintaining this separation, we avoid thepotential duplication and incompatibility of potentially conflicting standards/requirements while providing theappropriate industry standards necessary to ensure public safety and properly designed products.

While these levels are probably too permissive, they are a good start towards homologation with the SAEregarding the option of using a vehicle as a generator substitute.

Reighard, Karl

Because the NEC does have jurisdiction over cables or other conductors used to attach electric generationsystems to premise wiring, and the type and rating of the connectors used on those cables/conductor assemblies,it makes sense to allow jurisdiction over the outlet on the vehicle to which those cables/conductor assemblies willattach. Care must be taken that this is not used as justification to extend the NEC jurisdiction beyond that pointand deeper into the on-board vehicle electrical system. Language to specify that jurisdictional limit should beadded for clarity during the upcoming code cycle.


The Second Draft has an improvement in that it provides for lower voltage outputs to be exempt from theserequirements. A strong argument could be made that lower power devices, even those operating at 120VAC,should also be exempt from the requirements. Furthermore, 120VAC inverter systems that are designed to theSAE J1766 requirements and/or FMVSS305 requirements already have suitable protections against electric shockhazards and hence additional requirements in the NEC are not needed. Voter fully agrees with Mr. Karl Reighard’scomments that CMP-12 needs to be careful to avoid requirements that move deeper into the on-vehicle electricalsystem. This is precisely why SAE has been advocating for a very clear distinction between off-vehiclerequirements being covered by NFPA and then NHTSA/SAE covering on-vehicle requirements. Voter also agreeswith Mr. Jeff Holmes’ comments that on-vehicle hardware is outside the scope of the NEC, and implores theCorrelating Committee to drop all on-vehicle requirements. However, assuming this ambiguity in the Codecontinues to exist, this non-negative vote is simply an indication that the Second Draft text is slightly moreappropriate than the First Draft text for this requirement.


Holmes, Jeffrey L.

The phrase, including the outlet on the vehicle, should be omitted. Section 90.2(B)(1) clearly states that this codedoes not cover automotive vehicles other than mobile homes and recreational vehicles.

An important clarification for safety.

Reighard, Karl




This proposed second draft revision should be rejected so the Code reverts back to the first revision text. This SDproposed text, along with the text of SD 7776, incorrectly expands the scope of the NEC in direct conflict withsection 90.2. In all foreseeable cases, off-vehicle power transfer system equipment will be connected to someform of an electrical infrastructure and hence there is no objection to an NEC requirement that this equipment belisted (as stated in the first revision text). However, governmental requirements for on-vehicle equipment are underthe jurisdiction of the National Highway Traffic Safety Administration (NHTSA) and automotive industry standardsare controlled by SAE International. NFPA-70 should not attempt to include requirements for automotiveequipment. Furthermore, there are currently no listing requirements or test procedures that appropriately accountfor the environmental and duty-cycle requirements of automotive applications. Appropriate procedures and testrequirements should be put in place prior to any NEC requirement that these procedures and requirements beimplemented. Primarily for these reasons, on-vehicle equipment should be consistently and completely excludedfrom the NFPA-70 standard.

As written, the SD text does allow programmable changes to the maximum output of the EVSE, but it does notprovide any limitations on how this adjustment can be made other than the need to restrict access via one of themethods listed. Voter suggests restricting this programmable ability to on-site equipment only with the goal ofpreventing remote or internet-based changes which would likely be more susceptible to cyber-attacks or humanerrors that could allow excessive power flow through the EVSE.


Holmes, Jeffrey L.

Allowing the user, with just a tool, to adjust the current settings on EVSE doesn't seem to safe. The other optionsrequire a qualified person.

Reighard, Karl

The electric utility industry (as represented through the EEI) finds no problem with, nor has any direct commenton, this SR - the change it proposes is a good change and will make the code easier to enforce - this section ofthe code is one of many that illustrate the inadequacy of the NEC, shaped and limited by its historical structure,scope and intent, to govern EVs in a rational manner. Because you have generation, distribution, storage, andconsumption all within a single mobile entity that can at any moment act as a generation device, a storage device,a consumption device, a combination of those or none of those as seen by the outside world, it does not fit into thecurrent root structure of the NEC. Worse yet, under some of those conditions it falls completely outside of NECjurisdiction even by any stretch of the imagination. For these reasons it makes sense to spin EV regulation out ofthe NEC and into a code devoted just to EVs, with correlating elements to keep that code in sync with the codesregulating those things with which EVs will interact or interconnect during their various modes of use.


Strongly suggest dropping the last sentence of this section: “EVPE that consists of a receptacle outlet only shallbe in accordance with 625.60.” Paragraph 625.60 is able to stand on its own and there is no need to cross-reference requirements within the code which just adds complexity with no additional clarity. The CorrelatingCommittee should drop this phrase to be more consistent with the rest of NEPA-70. Voter agrees with KarlReighard’s basic comment that the on-EV equipment should be dealt without outside of the NEC. However, nonew documents are required because there are already existing standards and processes in place that cover on-vehicle equipment. The U.S. National Highway Traffic Safety Administration (NHTSA) has authority to requiremanufacturers to conform to safety requirements in the Federal Motor Vehicle Safety Standards (FMVSS); theagency also has general recall authority. As a result, any safety-related concerns with AC outlets are covered byexisting NHTSA processes. NFPA-70 should not attempt to include requirements for automotive equipment, eitherin NFPA-70 or in another document, because with this scope expansion there is the potential that NFPA’s on-vehicle requirements could directly conflict with existing or future NHTSA regulations or SAE Internationalstandards.

There are no mechanisms in the field for an AHJ to confirm compliance to requirements for on-vehicle equipment.Regulations covering vehicle design are established by the National Highway Traffic Safety Administration(NHTSA) which does have all the appropriate procedures in place to confirm automotive compliance to itsrequirements. The vote to affirm this change is just to suggest the SD text is marginally better than the FD text forthis requirement. The voter implores the Correlating Committee to consider the potential impacts to AHJs ofintroducing any requirements in the Code for on-vehicle equipment. Also for the Correlating Committee: ifSD-7792, requiring all equipment to be listed, does pass the SD ballot, then SD-7796 becomes superfluous andcan be dropped from the Code with no change in meaning. Voter agrees with Mr. Jeff Holmes’ comments that on-vehicle hardware is outside the scope of the NEC, and implores the Correlating Committee to drop all on-vehiclerequirements. However, assuming this ambiguity in the Code continues to exist, this non-negative vote is simplyan indication that the Second Draft text is slightly more appropriate than the First Draft text for this requirement.


Holmes, Jeffrey L.

Section 90.2(B)(1) clearly states that this code does not cover automotive vehicles other than mobile homes andrecreational vehicles.

(C) Overcurrent Protection.

Electric vehicles provided with receptacle outlets for power export shall be provided with integralovercurrent protection integral to the power export system . The overcurrent protection shall have anominal rating sufficient for the receptacle it protects. The overcurrent protection shall also be sufficientlyrated for the maximum available short-circuit fault current at the receptacle and shall be included in theinteractive equipment evaluation. See 625.48.


Committee: NEC-P12


Committee Statement

CommitteeStatement:

The intent of the requirement is to require overcurrent protection be provided to protect thereceptacle and offboard utilization equipment connected to the receptacle. The protection can belocated other than integral to the receptacle and still accomplish the function. Short-circuit has beenchanged to fault in order to be consistent with the remainder of the document.

The electric utility industry recognizes the need for adequate protection for personnel and because of thatsupports the proposed change on a safety and technical level, and applauds the relaxation of the previouslanguage to now allow the location of the overcurrent protection to be in places other than the receptacle locationitself, hence the affirmative vote. We do not, however, recognize the jurisdiction of the NEC to regulate the on-board electrical systems of vehicles in whole or in part with the exception of the connector used to attach an EV toa premise wiring system. The language of this section is should be modified to clarify that jurisdictional boundary.

The 2nd Committee Review Stage Terra pages (and online PDF SRs 7800 and 7801) show both "On-BoardInverters" and "Marking" as 625.60(E), "Marking" is actually 625.60(F). The strikeout text portion of SR 7801shows this as "(E) Marking" instead of "(F) Marking" As correctly shown in the title, "Marking" was 625.60(F) -delete in its entirety.

Johnson, Robert E.

Confusion exists over (E) versus (F) in the title. Section on marking should be deleted as shown.

Reighard, Karl



The Voter agrees with the comment by the chair that the agreement was to drop the Marking paragraph for625.60, without regard to what letter is assigned to that paragraph.

Joiner, Mark S.

The interpretation of "panic hardware" is one of the most overlooked and missed requirements in life safety. Mostlocal and state plan reviewers are confused by the current verbiage in this section. These changes should helpclarify the proper materials which shall be required. I would also encourage NFPA to add this requirement in theNFPA 101 Life Safety Code as it is not addressed in any of it's occupancies or in Chapter 7 "Means of Egress" ofthe Life Safety Code. Therefore it is rarely enforced or cited as a defeciency by Fire Prevention inspectors. Mostelectrical inspectors are not familiar with egress requirements and if it is not cited in plan review it is overlooked.
