Use 6-15R or 6-20R. I think it would pass inspection because most safety requirements around gfci and afci don’t apply to 240V circuits

They do now, but only when accessible by a person. Even car charging station outlets do (even though every car charging station has gfci built in...)

Ah looks like this was a change in 2017. With any outlet there’s no guarantee what will end up plugged in so it’s logical to require it even if the purpose is an EV charger.

Thanks!

EU is on 50hz AC, where as the US is on 60hz. It would work fine for purely resistive appliances, and possibly devices with switching mode power supplies, but some devices would be unhappy plugging in to the wrong frequency at 220V.

I'm not sure about the phase alignment but that may be an issue as well. US is split phase, but Europe has 220 on a single conductor?

it's 230 (+-10%) nominal not 220. At my house it's around 235. It's 230v phase/live to neutral and 400V between live wires in 3phase. Nowadays 3-phase (120degree between each) is a commodity.

In my part of USA the typical voltage between the two sides of a breaker box is 240V. It actually moves around a bit below that value, but doesn't seem to ever exceed 240V. I think most consumer devices have the circuitry necessary to survive such variation, but I have seen some (expensive) professional equipment fried in an instant...

Thanks for that. Sounds wonderful compared to the typical 200 amp, split phase service we commonly have in the US.

How many non-switching power supplies will care either?
