Applied the code required protection from contact with live parts (Section ) as the means to specify which appliance shall be listed.

5 of 50 1/28/2016 2:35 PM Williams, Matt B. Yasenchak, Randy J. Negative with Comment Cook, Donald R. While I agree that listing of some appliances may not be necessary to achieve protection from shock and fire, I don't agree with using a 50 volt line of demarcation. I would recommend relief be provided by an exception. See the following recommended text for Listing Required. All appliances shall be listed. Exception: Appliances supplied or charged by a listed Class 2 power source. NEC Panel 17 Final Ballot Results - Page 5 of 53-01/28/16

While always supportive of listing and generally supportive of labeling of listed products, it is obvious that many variables impact labeling of different products throughout the NEC. The CC approach to have a task group review this issue across the NEC is likely the best approach to ensure practical and uniform application of this concept.

20 7 of 50 1/28/2016 2:35 PM Second Revision No NFPA [ Section No ] Clearance from Other Objects and Openings. Heating elements of cables installed in ceilings shall be separated at least 200 mm (8 in.) from the edge of outlet boxes and junction boxes that are to be used for mounting surface luminaires. A clearance of not less than 50 mm (2 in.) shall be provided from recessed luminaires and their trims, ventilating openings, and other such openings in room surfaces. No heating cable shall be covered by any surface-mounted equipment. Submitter Information Verification Submitter Full Name: CMP 17 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Nov 02 17:50:40 EST 2015 Committee Statement Committee Statement: As amended in the First Revision, 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 manufacturers of heating panels or heating panel sets shall provide marking labels that indicate that the space-heating installation incorporates heating panels or heating panel sets and instructions that the labels shall be affixed to the panelboards to identify which branch circuits supply the circuits to those space-heating installations. If the heating panels and heating panel set installations are visible and distinguishable after installation, the labels shall not be required to be provided and affixed to the panelboards. Submitter Information Verification Submitter Full Name: CMP 17 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Nov 02 18:26:55 EST 2015 Committee Statement Committee Statement: Response Message: Circuit identification is already adequately addressed by 408.4(A) which requires all circuits and circuit modifications to be marked at the panelboard by a suitable method determined by the installer and accepted by an AHJ. There is no direction as to the size, shape, color or placement of the label, just that the label be affixed to the panelboard and identify the branch circuit(s). The manufacturersupplied label rule only applies to heating panels and heating panel sets but not to heating cables. The electrician can provide a more complete description of the location of the heating panel.

All electrical equipment installed in the water, walls, or decks of pools, fountains, and similar installations shall comply with the provisions of this article. Equipment and products shall be listed and labeled. Submitter Information Verification Submitter Full Name: CMP 17 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Tue Nov 03 11:03:35 EST 2015 Committee Statement Committee Statement: Response Message: The text listed alone would allow for listed units that would require the Inspection Authority to search in various databases of the certification agencies while conducting inspection in the field. This is inconvenient and sometimes difficult. The text and labeled was added as this would mandate a certification (listing) mark on the product or its smallest unit container for small components such as wire connectors. The text for swimming pool use was not added to this section as it would then apply to all electrical products used in the Article. This would include conduit, wire connectors and grounding and bonding equipment that are not listed for swimming pool use. Text such as identified for swimming pool and spa use would be appropriate in other sections of the Article.

34 1 of 50 1/28/2016 2:35 PM Second Revision No NFPA [ Section No ] Grounding and Bonding Terminals. Grounding and bonding terminals shall be identified for use in wet and corrosive environments. Fieldinstalled grounding and bonding connections in a damp, wet, or corrosive environment shall be composed of copper, copper alloy, or stainless steel. They shall be listed and labeled for direct burial use. Submitter Information Verification Submitter Full Name: CMP 17 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Tue Nov 03 11:05:58 EST 2015 Committee Statement Committee Statement: Response Message: The requirements for grounding and bonding equipment in UL 467 do not at present have an option of a rating wet or corrosive environments. Requirements in UL 467 for a rating of direct burial would mandate materials that have proven resistant to the corrosive environments around swimming pool equipment: stainless steel, copper and high copper content copper alloys. The text or concrete encasement is not necessary as the marking for the listed terminal would be direct burial or DB. The text and labeled was added as this would mandate a certification (listing) mark on the product or its smallest unit container for small components such as wire connectors. The text listed alone would allow for listed units that would require the Inspection Authority to search in various databases of the certification agencies while conducting inspection in the field. This is inconvenient and sometimes difficult.

In conjunction with this SR, we request that the Technical Correlating Committee also consider making an editorial change by adding the phrase or power supply to the Exception after the word transformers. Panel 17 has modified 680 consistently to add or power supply to references involving transformers for low voltage pool lighting in order to address the new solid-state low voltage lighting technologies that may utilize a power supply instead of simply a transformer.
