1 National Fire Protection Association 1 Batterymarch Park, Quincy, MA Phone: Fax: TO: NEC Code-Making Panel 3 FROM: Kimberly Shea, Administrator, Technical Projects DATE: January 25, 2016 SUBJECT: NFPA 70 Second Draft TC Ballot Final Results (A2016) According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot with the exception of SR No As a result, the revision is now designated as Committee Comment No. 601 and will not be included in the Second Draft. Second Revision 601 has no related First Revision, therefore, there will be no supplemental ballot. The attached report contains Committee Comment No. 601 and the SRs created by Panel 3 with final ballot counts and voting comments. To pass ballot, each revision requires: (1) a simple majority of those eligible to vote and (2) an affirmative vote of 2 /3 of ballots returned. See Sections (c) and of the Regulations Governing the Development of NFPA Standards. NEC Panel 3 Final Ballot Results - Page 1 of 58-01/28/16

2 of 2 1/25/ :16 AM Committee Comment No. 601-NFPA [ Section No [Excluding any Sub-Sections] ] This was a Second Revision that failed ballot. Where subject to physical damage, conductors, raceways, and cables shall be protected. Informational note: Minor damage to a raceway, cable armor or cable insulation does not necessarily violate the integrity of either the contained conductors or the conductors insulation. Submitter Information Verification Submitter Full Name: CMP 3 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Nov 02 11:49:07 EST 2015 Committee Statement Committee Statement: Response Message: The informational note provides guidance to an electrical inspector that minor (superficial) damage to the jacket of a cable is not an issue. The first sentence of the proposed informational note is unnecessary since it states the obvious that physical damage doesn t just occur from normal building operation.

The AHJ already has the authority to made a determination whether or not external damage may affect the conductors within. This is not necessary and will cause confusion. Straniero, George A.

It is understood to limit the installation of cables in ducts as much as possible, however 4 feet in a total system with multiple devices is impractical. Limiting the length to 4 feet per device makes more sense. NEC Panel 3 Final Ballot Results - Page 27 of 58-01/28/16

The effective date shall be January 1, Submitter Information Verification Submitter Full Name: CMP 3 Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Mon Nov 02 17:03:37 EST 2015 Committee Statement Committee Statement: Response Message: This new section addresses labeling of limited power circuit output connection points on listed IT equipment and listed industrial control panels and equipment. Bundling of large numbers of Class 2 conductors from IT servers and other similar IT and industrial equipment can create safety issues with very small current levels so having the output ports identified with the current and voltage rating is critical so the installer can connect the proper cable types. Labeling the output connections will permit the installer to have ready access to the current and voltage levels at the point of connection at the equipment, rather than internally within the equipment. The effective date was inserted to allow the manufacturers to comply with this requirement.

With the introduction of the ampacity tables that provide current limits for different AWG sizes and the optional use of LP cables that are rated for maximum current handling capabilities, the power source capabilities need to be identifiable by installers and AHJs in order to properly match the power source with the cable s current handling capabilities. It is our understanding based on the Committee Statement and the new reference that it is intended to apply to powering over LAN cable applications that include power and data transmission.

This PI has been accepted as a Second Revision (#620) without fully evaluating the substantiation provided by the submitter. Comments from the Panel Members prior to the vote for the First Revision indicated many had issues with this PI's substantiation and the concept of various floor coverings being installed over cables without maintaining access to the cables. UL's Fact Finding report, the substantiation for the First Revision, considered the heating effects of CMUC cables installation under these floor coverings and did not consider any damage incurred during installation or maintaining access to the cables once the floor system itself is installed through the use of fasteners, adhesives whether permanent or temporary, the resultant damage covered and hidden from view.the floor products themselves are often not installed per their installation guides, the cables underneath non-withstanding, by unqualified persons with little or no understanding of what they are dealing with or covering.many floor covering products are available, have they ALL been evaluated in this type of installation? This can be readily seenin all types of occupancies, with underfloor heat tapes and cable mats covered by ceramic tile or floor coverings, but they are protected by a GFCI as required in Art Carpet tiles are limited in size to 1 square meter to ensure ready access for future inspection for installations of FCC cables under floor carpet tiles. FCC cables have been exposed to all kinds of abuse not contemplated in their approvals. Additionally, building owners began to cover these cable installations with full carpeting and even padding when the carpet tiles were damaged, lost or just didn't meet the owners design scheme anymore. This same scenario is now possible for all floor coverings installed over CMUC cables. Further study and evaluation is warranted for this type of installation, with all of the supporting documentation provided to the panel for evaluation and consideration.
