GE 50 Amp Temporary RV Power Outlet-U054P - The Home Depot
Something similar to this is what I’ve seen at a lot of people do for an outdoor 14-50. I don’t own one personally but it’s what I’d want if I was doing an outdoor install
That’s what I use. No issues to speak of so far, 20 months in.
You can’t close/lock it while the UMC is plugged in, but the cover keeps the water off it.
Sorry, gen 1. Thanks for pointing that out.Are you using a Gen 1 or Gen 2 UMC? I'm pretty sure I bought the same enclosure from Lowes and it does close all the way with the Gen 2 adapters.

Do you happen to know which subsection this is in?Note that in 2017 NEC in Article 625 is a new requirement that all EVSE receptacles be GFCI protected.

Thanks!
Great, thanks!625.54 or 625.56 I believe. Am at dinner on my phone. I have posted about it elsewhere on this forum.
Looked it up, it is 625.54 - good memory!625.54 or 625.56 I believe. Am at dinner on my phone. I have posted about it elsewhere on this forum.
Does this apply to a 240v circuit? Obviously 240 > 150 but are they considering each 120v phase separately?625.54 Ground-Fault Circuit-Interrupter Protection for Personnel. All single-phase receptacles installed for the connection of electric vehicle charging that are rated 150 volts to ground or less, and 50 amperes or less shall have ground-fault circuit-interrupter protection for personnel.

thinking about doing this for a future house ill be living at, as it has no garage. Ill just tell the installer that its for an RV and no questions will be asked about EV charging
my only hope is nobody steals the UMC as i dont plan on unplugging it everyday.
I would call out that telling your electrician something is intended for an TV might result in different NEC load calculations (since RV's probably typically draw a fraction of what an EV does), so it could in theory make a difference (but yeah, in most practical situations, probably not).
As to the stealing of the UMC: Again, that is one reason I am a fan of the Wall Connector (though I am sure there are ways as others pointed out of building a custom enclosure for it).
I spoke to my electrician friend, who spoke to the engineer who designs all of the car charging installations for his company (a fairly large electrical company). He says that GFCI protection is not required for a 240v circuit.Yes, this applies. Residential service in the US is 120/240v split phase, so this means neither "hot" leg is more than 150 volts to ground. So yes, they intend to require GFCI's on *ALL* EV outlets.

I will be calling and talking to one of the city inspectors later today, hopefully he can bring some clarity to the situation.

I was just about to get that. So theres not enough space with the plug?
Has anyone found one that can be closed when plugged in?
I specifically mentioned 625.54, he said it doesn't apply to 240v circuits. Therefore 625.22 is the one to pay attention to. His words:I am genuinely curious what he would say about NEC 625.54. Would you mind asking him (send him a copy of the text of the article)?
GFCI is not required for hard wired HPWC’s but 625.54 is very clear that it is required for receptacles.
It is also possible that he is correct in the market he works in - either they may not have adopted 2017 NEC yet or they may have modified it.
Please report back on what your electrician friend and inspector say!
I spoke with our engineer and he elaborated on the requirements for GFCI in a situation like that, pretty much a dwelling unit receptacle like that is exempt. 625.22 is the major article to pay attention to, that puts the onus of personnel protection on the manufacturer of the vehicle. When we install charging stations all personnel protection is built in, be it GFCI or, I believe in Tesla’s case, CCID. This protection should be built into the cable plug for the Tesla charger.
As for the part that talks about 150 V to ground, that does not apply to a 240 V outlet. Only 120v circuits.
So technically, there has to be protection, but it’s not on the electrical installation side.
