First Time EV Owner - New Emporia Classic at 48A. Is this too hot?

He finally agreed to wire it with THHN in conduit.

In the end he wired it with 6/3 NM-B Romex with a 60 amp breaker. We had to derate the Wall Connector to 40 amps and replace the breaker with a 50 amp breaker.

He agreed to THHN and then did it in Romex anyway??! Did you make it redo it?

It wasn’t my house. I was advising my friend with a new EV who was having HIS new house built. He was acting as his own general contractor and the electrician was a sub contractor he hired.

When he called me and told me that the wire had been run I asked his to verify it was not NM-B Romex and it was actually SE CU cable. He took the picture below and sent it to me. It was NM-B Romex. The drywall wasn’t even up yet.

I told him to have the electrician to rerun it with proper 60 amp wiring, either SEU Copper or THHN in proper conduit while the drywall was still not up. He didn’t want to confrontation so he let it go. He told me later that he was concerned that the electrician would charge him to redo it. A GC wouldn’t have let it go. He’s just a wuss. His standard line is “ I’m not worried about it, it’s good enough”.
