Cor, yes, you are 100% correct, but there are also many shitty EVSEs out there that aren't "well designed" or even UL listed. They are all over Amazon, and people buy more of them every day. As proof, I have several that were given to me that trip the upstream GFCI as soon as they are connected,

Phil, NOPE! The *correct* designed EVSE will have a test circuit that indeed generates a GFCI test fault current but *only* in the EVSE's GFI circuit, not in the upstream 240V connection. The reason that an EVSE often trips the upstream GFCI is not due to the EVSE but due to the *huge* capacitance

IIRC, J1772 specs 20ma. So it will likely put an over 20ma ground fault intentionally during its self test. On Fri, Apr 12, 2024 at 12:01 PM EV List Lackey via EV wrote: > On 12 Apr 2024 at 13:35, Mark Hanson via EV wrote: > > > An HTML attachment was scrubbed.. > > Thanks Phil etc > > Sometime

Yes, the 12" restriction is because all EVSEs are required to have integral GFCI protection, but of course this will do no good for wiring "before" the EVSE, so they mandate this cable is as short as possible. EVSEs are used in mechanically hostile environments, so it's likely that a certain perc

Yeah the EVSE's GFCI is required to self-test, so that self test can trip an upstream GFCI. Which means every time you try to charge you get a nuisance trip. If you must install a GFCI on your 14-50 because of your local AHJ, try to obtain a 30ma unit not a 6ma. Best thing to do is hardwire it s

NEC article 625.17 has a mention that the input cord length shall not exceed 12” if the personnel protection system (GFI?) is located in the EVSE enclosure. That appears to be an ‘out’ for needing a GFI breaker? Just speculation. Tom Keenan > On Apr 12, 2024, at 7:14 AM, Mark Hanson via EV wr
