1 National Fire Protection Association 1 Batterymarch Park, Quincy, MA Phone: Fax: MEMORANDUM To: NEC Code-Making Panel 17 From: Kimberly Shea, Project Administrator Date: April 17, 2015 Subject: NEC First Draft TC FINAL (A2016) According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot. 13 Principal Members 9 Eligible to Vote on All Articles 4 Vote Limited 0 Members Ballot Not Returned 4 Members voted Affirmative with Comment on one or more Revision (Blewitt, Cook, Shell, Yasenchak) 7 Members voted Negative on one or more Revision (Blewitt, Cook, Jhonson, Querry, Schapp, Williams, Yasenchak) 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 = = 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 = = 12 ) As always please feel free to contact me if you have any questions.

Negative with Comment A requirement that all listed equipment be labeled with the listing organization's mark of conformity conflicts with the definition of Listed in Article 100, including the Informational Note saying," Use of the system 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 Informational Note (or an Appendix note in many NFPA standards). it is not for CMP 17 to decide to override an official definition. In addition it is inappropriate for the NEC Committee to dictate certification practices to listing organizations. By requiring that listed equipment display the listing organization's mark, CMP 17 would be dictating the business practices of the listing organizations without a clear statement of need, against the advice contained in the Informational note to the definition.

Williams, Matt B. Negative with Comment 1) The committee statement only states that the appliance would need to be listed. Should the statement also

6 of 141 4/17/2015 2:48 PM include the word labeled as well? 2) Requiring the appliance to be listed and removing the definition would require a code user to fall back to the definition of appliance listed in article 100 which does not list vending machine as part of the definition and give the impression that industrial machinery is excluded. The user would then fall back to the definition in Webster's dictionary for the definition of vending machine. The definition in Webster's dictionary states: (a machine that you put money into in order to buy food, drinks, cigarettes, etc.)not all vending machines require money to be inserted to provide a service or product. it might be better to leave the definition in place or revise the definition to better fit the requirements of article 422.

7 of 141 4/17/2015 2:48 PM First Revision No NFPA [ New Section after ] Listing Required. All appliances shall be listed and labeled. Submittal Date: Mon Jan 12 11:28:22 EST 2015 Committee Statement: Response Message: All appliances should be listed and labeled to classify the equipment and to ensure application of proper installation requirements. Public Input No NFPA [New Section after 422.5] 11 Eligible Voters 9 0 Affirmative with Comments 2 Negative with Comments Swim, Peter C. Negative with Comment New Requiring "listing" of all appliances is appropriate. It is not appropriate to require "labeling". Refer to negative comment to FR 4803.

8 of 141 4/17/2015 2:48 PM Williams, Matt B. Using a universal mandated of listing of all appliances will not solve the issues presented and will likely cause more confusion. In the complex world of utilization equipment, there are many different products under the term appliance. Art. 422 contains specific requirements for certain equipment but not for most types. We appreciate the desire to have all appliances safety certified, but the voluntary system of safety certification of the US has achieved virtually 100% compliance. The challenges of mandating this are many. The current definition of appliance in the NEC may work for the Code but this proposal would now require all Certification Organizations (CO) to comply with this definition for all products under specific standards. The premise of the proposal that this would bring greater clarity or uniformity is unfortunately not true. There are many problems with the insertion this phrase. 1. The addition of this language could require that AHJ s take on the role of determining if a piece of utilization equipment is an appliance and if the appropriate standard has been used. The AHJ may not have the necessary information on the internal technology of the product, its functions or the usage to make this determination. 2. Not all Nationally Recognized Testing Labs (NRTL) CO s will use the same determination of a product and thus products in between standards will be listed, but not to what the AHJ may agree. This could put the AHJ in the awkward position of determining if the product has been properly listed. 3. To require listing of a product also requires under the definitions found in NFPA 70, that the product be put onto a list. This implies that this list would be used by an AHJ for purposes of determining if the product has been evaluated properly. However, each CO may not agree and the same products could be on different lists. 4. Many products do not carry a description of the product type when obvious. Where products are new or innovative, requirements from multiple product standards may be used. This proposal will not help AHJ s determine compliance. 5. Many appliances function on low voltage systems either through an external power supply or battery charger. Frequently, only the conversion portion of the appliance is listed and not what some would consider is the appliance. The proposal would create a conflict between the Code and the listing requirements. These low voltage appliances will not appear on any list accessible to the AHJ. 6. Short runs of sample products may be used to gauge consumer interest and may not be certified at the time they are used for marketing purposes. This code change will cause difficulty for companies trying to bring new products to the market quickly. 7. Marking, listing, and categories of products are governed by the certification rules of the CO, may not be in the safety standards and may not agree with the specific designations within Art Between CO s there is a great deal of variability with respect to when the product must be marked with its category or classification or even the term that is used in the marking or category of a list. This proposal will not bring uniformity to the process. Appliance end-product safety is addressed by nearly 100 safety standards, including component standards, developed by consensus stakeholder committees composed of knowledgeable individuals about that particular product and which rapidly change with technology. The solution to the issue raised by the maker of the proposal would be for the Code to clearly define what constitutes each of the special installation requirements for appliances (such as dishwasher, refrigerator, vending machine, drinking fountain, etc.) that may be beyond the applicable safety standards. The proposal as presented will not bring clarity or uniformity to the process of safety and will make the work of the NEC and the AHJ more difficult.

9 First Revision No NFPA [ Section No ] Ground-Fault Circuit-Interrupter (GFCI) Protection for Personnel. The device providing GFCI protection required in this article shall be readily accessible. (A) General. Appliances identified in 422.5(A)(1) through (7) rated 250 volts or less and 60 amperes or less, singleor 3-phase, shall be provided with GFCI protection for personnel. Multiple GFCI protective devices shall be permitted but shall not be required. (1) Automotive vacuum machines provided for public use (2) Boat hoists (3) Drinking water coolers (4) Dwelling unit dishwashers (5) High-pressure spray washing machines cord-and-plug-connected (6) Tire inflation machines provided for public use (7) Vending machines (B) Type. The GFCI shall be readily accessible, listed and labeled, and located in one or more of the following locations: (1) Within the branch circuit overcurrent device (2) A device or outlet within the supply circuit (3) An integral part of the attachment plug (4) Within the supply cord not more than 300 mm (12 in.) from the attachment plug (5) Factory installed within the appliance Submittal Date: Mon Jan 12 11:10:45 EST 2015 Committee This revision incorporates concepts to collect GFCI requirements from and throughout Article Statement: 422 related to personnel hazards from specific equipment (contact with equipment with excessive leakage current) and provide those requirements in a single location. Those hazards could be associated with abnormal conditions in equipment related to intentional or unintentional physical abuse, harsh environment, or simply end of life. Collection of GFCI requirements will increase clarity and usability. GFCI protection for general purpose outlets related to locations and environmental factors, not specific equipment, remain grouped in Review of UL 943, Standard for ground-fault circuit-interrupters covers single and three phase protective devices that operate at several voltage of 141 4/17/2015 2:48 PM

10 levels all rated 250 volts or less. Based on the voltage limitation of the product standard, the 250 volts or less was used in It was determined the personnel hazards are related to abnormal conditions for the specific equipment considered and do not change at 250 volts or less nor do they change where the equipment is single or three phase. While UL 943 does not limit application to 60 amperes or less, that ampere rating appears to cover products that are commercially available. While previous GFCI requirements included a variation of protective device locations, it was determined the hazard is associated with a person coming in contact with the equipment while grounded at the same time the equipment is in a condition that allows current to flow outside the intended path. It was determined the location of the GFCI protective device was not relevant to the safety of the person. Revisions permit the protection to be provided by any protective device listed and labeled to UL 943. This revision provides owners, designers, and installers the ability to select the location most suitable for the owner needs and be able to select an option that allows for testing of the GFCI protective device. While current NEC and product standards require GFCIs to be incorporated in plugs or cords provided with the appliance, older equipment will not include that protection. It is also recognized that portable GFCI devices are not currently available in 60 ampere three phase configurations. Where the appliance includes GFCI protection revised text does not require additional protection but recognizes that multiple levels of protection are compatible and do not cause any safety or operational concerns. Revision also recognizes incorporation of GFCIs within products is an issue to be resolved within the product standard. Revision also changes electric drinking fountain to drinking water cooler based on the term used in the applicable product standard.

11 Swim, Peter C. Williams, Matt B. Negative with Comment The new current text would require that the appliance itself would be required to be provided with the GFCI protection. 1) This would allow the circuit to be installed into the area where the GFCI protection would be needed to not be GFCI protected. 2) Would it be better to give the option to allow the purchaser of the equipment to buy the equipment with GFCI protection or buy the equipment without GFCI protection and the installer of the circuit for the appliance to install GFCI protection of the circuit. The current proposed text in "A" gives the implication that the appliance is to be provided with the GFCI protection. Suggested rewording: Appliances identified in 422.5(A)(1) through (7) rated 250 volts or less and 60 amperes or less, single- or 3-phase,or the circuit providing power for these appliances shall be provided with GFCI protection for personnel. Multiple GFCI protective devices shall be permitted but shall not be required. 0 of 141 4/17/2015 2:48 PM

Since these appliances may either be protected by grounding or double insulation, the or its equivalent statement in the requirement could be deleted without affecting product design and to also avoid confusion. Negative with Comment 1) Both items 5 and 6 allow the receptacle to be located in the space adjacent to the appliance. This would often lead to the cord passing through a divider or wall. This would be in conflict with Article which does not allow flexible cord to be run through walls. The NEC does not give a definition for walls therefore the definition in Webster's dictionary would apply. Wall - a material layer enclosing space 2)Suggested wording for items 5 & 6: 5)Receptacles for trash compactors shall be located such that the associated flexible cord will be protected from physical damage. 6)Receptacles for dishwashers shall be located such that the associated flexible cord will be protected from physical damage.

Negative with Comment Article 430 permits a conditional remote disconnect for small motors (1/8 HP and smaller), but not for lager motors. This revision would allow a remote disconnect (not within sight) from an appliance with any size motor. The change is a reduction in safety with no substantiation. Panel statement indicates this action has clarified the requirement when in fact the revision is a major change without substantiation. IAEI does not support that action. The proposed language is a clear reduction in safety. The first level subdivisions was added in the 2011 edition of the NEC to add clarity to the requirements of the section. This addition was intended to clarify that for motors over 1/8 HP, the disconnecting means are more restrictive. The requirements of the old were merged into c. Since this section references an appliance HP rating, a motor driven appliance is implied. In come commercial kitchens appliances could be rated 5 HP or higher.

46 5 of 141 4/17/2015 2:48 PM First Revision No NFPA [ Section No (A) ] (A) Shall Not Extend Extending Beyond the Room or Area. Heating cables shall not be permitted to extend beyond the room or area in which they originate. Submittal Date: Tue Jan 13 11:17:12 EST 2015 Committee Statement: Advances in technology, product designs, and product standards make it unnecessary to restrict heating cables to the room in which they originate, particularly for floor warming applications. When there is a path from one room to another, such as a water closet to a vanity area in a bathroom, the floor can be warmed with one heating cable circuit without creating safety concerns if the manufacturer s installation instructions and other code sections are followed.

51 0 of 141 4/17/2015 2:48 PM Williams, Matt B. Negative with Comment As amended, the requirement no longer distinguishes between the heating and non-heating conductors of heating cables. The non-heating conductors are unnecessarily being required to be separated 8 in. from surface luminaire outlet and junction boxes and 2 in from recessed luminaires, their trim and ventilating openings. Such conductors are arguably no different from other current carrying conductors that are not similarly restricted in their location. The end of the second sentence refers to "ventilating openings, and other such openings in room surfaces" What ventilating openings is this referring to? Ventilating openings of the fixture or the ceiling? What other such openings in room surfaces is this referring to? Openings in a fixture? Openings in the ceiling? openings in a wall?
