Any way to tell what gauge an electrician used on my Tesla charger?
This guy I had do my Tesla charger in my garage was originally saying he was going to do 8 gauge wire and that’s what he always does and everywhere I read said you should do at least 6. He said 6 is over kill.
I said I’ll pay you extra for the 6 just to be safe and he said okay.
He got to my house and said he didn’t have 6 In his truck but said he’d go get some when he needed it. He never left so I asked if he ever went and got it and he said he ended up finding some 4 in his truck so just used that…
Is there anyway to verify this without drilling into my wall? All the instal is in my wall essentially so no wires are exposed I don’t believe.
Thanks.
