I’ve been using my HPWC for my 2017 S90 D for 3 years now. Car is now at 106k miles and my circuit breaker started tripping when charging at home. I typically charge at 72 amps on a 100 amp circuit. Could the car be at fault or are the circuit breakers likely bad? Any other ideas? I used a Tesla certified electrician years ago for the install. This is the first problem I’ve had charging at home except the very rare need to hit the reset button on the HPWC.

Thanks!
