Mr Perkins, Aware of the article 725 changes and other code stuff that would track this?

Having a 50V limit like the Euro LVD seems like a good harmonization effort. However, within TC108 we’re identifying a number of issues for ELV power distribution to other equipment (e.g. POE or 100W USB, etc.) to be safely used. There will be additional requirements for these schemes for them to be used safely and it will be part of the certification process under the standards. :>) br, Pete Peter E Perkins, PE Principal Product Safety & Regulatory Affairs Consultant PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 [email protected] From: [email protected] [mailto:[email protected]] Sent: Tuesday, July 26, 2016 5:15 PM To: Pete Perkins <[email protected]> Cc: EMC-PSTC <[email protected]> Subject: Re: [PSES] NEC 2017 Pete -- Thanks for the suggestion. I looked on the NFPA.org website at the NFPA 70 draft dated 4-8-2016 and there is a new section 422.6: "422.6 Listing Required All appliances operating at 50 volts or more shall be listed." The definition for "Listed" in article 100 of NFPA 70 is complicated (too much to re-type here) but: 1) sounds like an NRTL; 2) does not specifically use the term NRTL. The definition for "Appliance" in article 100 of NFPA 100 starts off: "Utilization equipment, generally other than industrial..." and gives a few examples that could be either household or commercial (e.g., washing machine, air conditioning units, food mixers, deep fryers). Hard to tell the intent of the changes here. I'm guessing from the format that both "Listed" and "Appliance" definitions are being tweaked this time around, but have not checked this against the 2014 version.

All of these changes are done in an open forum and the documents seem available; I don’t follow them, however. :>) br, Pete Peter E Perkins, PE Principal Product Safety & Regulatory Affairs Consultant PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 [email protected] From: Doug Powell [mailto:[email protected]] Sent: Friday, July 22, 2016 3:13 PM To: [email protected] Subject: Re: [PSES] NEC 2017 Have we established that the 2017 edition actually has NRTL vs Listed? I would like to hear some clause references since it is nearly 600 pages.

In doing so, the AHJs often take exception to some requirements, and add some requirements. In adopting the NEC, the AHJs must specify what “listing” means – what third-party certifiers are acceptable to the local or state AHJ. The NEC has not mentioned or specified by name a third-party certifier. AHJs accept third-party certifications according to their local or state rules. A specific NRTL certification may or may not be currently acceptable. Now that the 2017 NEC specifies NRTL, it will be interesting to see how the local and state AHJs accept specific NRTLs, or NRTLs by standards (as does OSHA), or blanket all NRTLs. Note that AHJs have different objectives than OSHA, who runs the NRTL program.
