Newbie here. My home was built in 2005 so it was prewired with a 40AMP Breaker and wiring in place specifically for a future EV vehicle. I installed the NEMA 14-50 outlet myself since the wires were just tucked away ready for future install of an outlet. It took all of 5 minutes. So I took delivery of the car last week (yeah!!!) and start charging at 40 AMPs. Of course it trips after 1 hour because I have a 40 AMP Breaker (I learned this after the fact that a 40Amp breaker should be limited to 32Amps). So I read up and learned I should be charging at 32AMPs and adjusted that from the car's max capacity charge. Things were good for 2 nights and I was getting 23-25 miles per hour charge at 32Amps. Then bam, it trips again last night. I reset the breaker this morning and it charges for 30 minutes and it trips after another hour. So tonight I cranked max charge down to 25Amps just to be super careful. So far so good and car is now fully charged. Anyone run a 40Amp breaker on a 14-50 outlet? What max charge are you getting? I'm not sure if I have 6 or 8 gauge wires at the moment, but I figure if I'm limiting it to 32Amp charges it should be within specs regardless.
