So I say HPWC/breaker, because I'm not sure what the problem was. My electrician came and looked at it and couldn't say definitively either. Likely a bad "breaker" so he replaced it(the breaker) and said I will need a new panel.

Since then, I have installed a smoke/carbon monoxide detector, just to be safe. A few times I could smell something burning, same smell as the time it almost caught fire, so I started charging at 30 amps....with a fire extinguisher handy. Side note, hanging out in the garage, I've gotten a lot of cleaning done. Charging at 30 seemed ok, but the breaker still got warm.

Now, a few weeks later, my car stopped charging. Turns out the breaker was getting hot and causing the HPWC to stop charging, but not tripping the 60 amp breaker. Also caused some adjacent breaks to get hot and trip.

So trying to determine my path forward. Replace breaker again? Or is the HPWC bad? If I let the breaker cool down, reset the breaker, and then reset the HPWC, it works but I'm not comfortable using it.

Thoughts?



Breaker for HPWC was installed at the bottom and you can see how it burnt upward.
