HPWC not working

[viper2ko]

It looks like you have 2 choices. If you are comfortable, replace the breaker and see if that resolves the problem. If not, call an electrician to trouble shoot the problem. It sounds like the breaker has gone bad if it will not reset. Just be aware that there could be additional problems that are not immediately obvious, so be careful and take it step by step. Good luck!

Yikes!!

Having worked on a lightning induced problem previously makes me ??
What AWG size is that wire?
What device grounded out the lightning currents? and is it OK?
I think the HPWC has gas tube protectors on L1,L2

Now you know why we have breakers! Someone else asked about the size of the wire. Please make sure the wire size is adequate for charging at 40 amps. It is hard to tell from the picture, but the wire looks smaller that what my electrician installed for my charger.

40 amp charging requires a 50 amp circuit. A 50 amp circuit requires 6 gauge wire and a 50 amp breaker. I doubt it was lightning. More likely it was a loose connection.

Loose connection would burn at loose connection location, not along the wire. This could be lightening but could also be overloaded wire (e.g. too small). OP, what awg wire is this, what amperage breaker was it connectected to, and is there anything else other than HPWC on the same breaker?
