Anybody else see/hear of this? I've never followed along with code development, but it sounds like we could be headed for another clothes dryer headache.
From what I recall it was forum member Bill Snyder here that made that proposal, Don mentioned it here: https://forums.mikeholt.com/threads/nec-or-ul.2582682/post-2940261
I hope your state can amend the code to remove this nonsense requirement. We have discussed on here many times how EVSE ground fault protection works:
EVSE and GFCI PROTECTION
Am I reading 625.54 correctly, if EVSE is plug and cord connected it must be GFCI protected, but if direct connected only if the manufacture specifies in the instructions? So in direct connecting an outlet for an EVSE it would be possible to skip the GFCI, UNLESS CALLED FOR BY THE MANUFACTURE...forums.mikeholt.com
That’s not a valid reason. Look at 625.17(A)(3). The cord cannot lay on the floor.GFI makes sense when it's an outlet and cord type setup, as the cord is likely laying on the floor of a potentially wet garage,
Tell that to the SecOps weenie who just pulled in his driveway after sitting in traffic for two hours following a 10 hour work day rebuilding customers' Ivanti firewalls. I guarantee you he has no clue that 625 even exists, nor cares enough to carefully route his power cord to meet the requirementsThat’s not a valid reason. Look at 625.17(A)(3). The cord cannot lay on the floor.
It does not have GFCI (5ma trip level). It likely has CCID-20 (20 ma trip level).since the charger itself has GFI built in as part of the design.
This is about the supply cord, not the one to the car.Tell that to the SecOps weenie who just pulled in his driveway after sitting in traffic for two hours following a 10 hour work day rebuilding customers' Ivanti firewalls.

I'd say its more about trip time than trip level, UL 943 is the only Class A standard that requires the 5-7ma trip level and UL 943 is not mandated by the NEC by reference.It does not have GFCI (5ma trip level). It likely has CCID-20 (20 ma trip level).
I don't see how that's possible, given the NEC definition and the Informational Note from the 2023 NEC, excerpted below.a device could meet the NEC definition of a GFCI and not have that 5-7ma trip level.
Informational notes are not enforceable.I don't see how that's possible, given the NEC definition and the Informational Note from the 2023 NEC,
No, but it's telling you that when the definition says "Class A" it means UL 943 Class A. Just like Appendix A does. I don't see how you can use a different standard when the informational note directs you to a particular standard.Informational notes are not enforceable.
So next you're going to tell me that while 240.7 requires circuit breakers to be listed, nothing requires them to be listed to UL 489? UL 489 incorporates the requirements for GFCI circuit breakers, and it references UL 943.There is nothing in the NEC that mandates following UL, just that its Class A protection.
No, but it's telling you that when the definition says "Class A" it means UL 943 Class A. Just like Appendix A does. I don't see how you can use a different standard when the informational note directs you to a particular standard.

(C) Explanatory Material. Explanatory material, such as references to other standards, references to related sections of this
Code, or information related to a Code rule, is included in this Code in the form of informational notes.
Such notes are informational only and are not enforceable as requirements of this Code.
No, the informational note's reference to UL 943 is not incorporating UL 943 into the NEC as enforceable language. Yes, it is telling you that the enforceable terminology "Class A" in the GFCI definition means Class A as per UL 943. The informational note is material that elucidates the enforceable material, rather than providing additional enforceable text.See 90.5(C)
Nothing in a informational note would be admissible as enforceable in court. The term Class A is probably also unenforceable.Yes, it is telling you that the enforceable terminology "Class A" in the GFCI definition means Class A as per UL 943.
