50 amp breaker
60 amp-rated wiring
I have attached an EVSE to the socket. The EVSE is rated at 40 amp continuous. I charge at either 3.3 kWh on one car, or 6.6 kWh on my Leaf (max charging rate on the 2020 Leaf SV).
Last night I had the Leaf plugged in and it was charging at 27 amps or whatever it does (I remember distinctly walking past and the car was blinking as it charged). However, this morning it had barely charged. Turns out the breaker was thrown. I put it back and now I'm charging my lower-charge car at 3.3 kWh.
Possible failure points:
- leaf's charger
A pro electrician installed the breaker and the wire, but I put the 14-50 socket in two months ago. I'm thinking even if I did a bad job and stressed the cabling on this it would either now be creating a complete short (and an instant breaker throw), or excessive heat or something, but nothing to actually throw the breaker...?
I can't imagine the leaf's onboard charger briefly asked for more than 50 amps and the EVSE should have rejected that anyway, right? Therefore I'm thinking the EVSE for some reason briefly pulled over 50 amps. Is that a safe bet?
