Re: [EVDL] NEMA 14-60? (was: NEMA 14-50 Receptacles for EVSE, EV Charging)

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.

[EVDL] NEMA 14-60? (was: NEMA 14-50 Receptacles for EVSE, EV Charging)

[Bill Dube via EV]

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 subsequently make a 14-60 to 14-50 adapter, but that would not 
be legal

PS

The trip limit of 5 mA on a North American GFCI is just plain silly. The 
rest of the world sets the trip limit to 30 mA for GFCI (or "Residual 
Current", as it is called elsewhere.) Hospitals, daycare centers, and 
the like, have lower trip limits, which makes sense in those specific 
locations.
