I suppose you could also install a 14-60 outlet and just cut the bottom
(neutral) pin off your EVSE's 14-50 plug. I've done that on many 14-50
portable EVSE plugs, then it fits in a 14-30 Dryer outlet too. (this pin
is not used on EVSEs) Just be sure and de-rate the breaker for safety.
I think the simplest would be to install a NEMA 14-60 with a 60 amp
breaker, and swap in a NEMA 14-60 cord cap on the charger.
If you are over 50 amps, you are exempt from the NEC GFCI requirements,
even outdoors. A bit silly, but this is what the NEC rules say you can
do
You could
