Yeah wasn't even thinking about it during his install. But I specifically told him that the charger needs a 60 amp breaker since the car will be charging at 48 amps according to the manual. I guess I'll keep it at 40 for now until I get around to replacing the small run with THHN. I could probably even just set the car to 44amps since 44x1.25 is the rated 55amps. Not that it makes a difference though. A little over 2 hours to recharge daily isn't bad at all.*sigh* 6 gauge Romex isn't rated high enough for a 60A circuit, so that would have to be set as a 50A circuit unless you do that change to THHN in conduit.
