Is the ground (not neutral) actually connected to earth ground? I have three 240 volt EVSEs from different manufacturers and none of them will work if the ground is not connected.I have pounded my head against the wall for a week now and am nearing my wit's end. I thought initially that because my electrician didn't ground the outlet to the conduit that my charger wouldn't work when I plugged into 240V. Part of the reason was that my ChargePoint Home Flex wasn't working either. I've literally looked at everything I can possibly think of down to the circuit breaker. I put a Square D Homelite dual-pole 50A breaker in to replace the Siemens one he put in my Square D panel, thinking that there may have been an incompatibility issue. Still no luck. I'm measuring 126V on each lead at the outlet. Does anyone have any ideas what could be happening? I can't live with L1 charging at home.
Note: the charger is in the car. What everyone calls a "charger" is properly called an EVSE (Electric Vehicle Supply Equipment).
You must power the EVSE BEFORE it is connected to the car. If done in the other order there will be a random start delay of up to 30 minutes. This was done so that after a power failure every EVSE connected to the power company does not turn on at the same time when power is restored.
