No problem, we can use the help. I’m not an electrician but trying to recall the quick conversation I had with him when he did the estimate for the job. He knows I want to take advantage of the full ChargePoint capability so ill see what he puts in next Saturday.@Skirmish Sorry, I'm not trying to be a jerk here, but just trying to note a calculation error. For 50 amp charging you would need a 70 amp breaker, not a 80 amp breaker.
@GrayEagle61 If your electrician said a 30 amp breaker was needed, then he made a mistake. You would need a double pole 60 amp breaker to reach the max charge rate of the car (@ 48 amps) or you would need a 70 amp breaker to reach the max charge rate of the ChargePoint Home Flex EVSE for another vehicle that can charge faster.
Again, not trying to do anything but provide some help.
