Installed a 40amp car charger (slrpnk.net)

Installed a 40amp circuit for the EVs after charging a PHEV for 5 years and a BEV truck for almost a year on a single 15amp circuit.

50ft x 8 AWG x 4 wires isn't cheap ($1.32/ft with tax), plus conduit, straps, breaker, wet location boxes and outlet cover and the extra cost for an EV rated outlet.

Wasn't room between the post and the garage door king stud for a flush mount box, oh well.

I'll pay the electrician for a proper hard-wired charger when we upgrade service and run it from the main panel instead.

EV rated outlets are a scam. I know the Internet is obsessed with this idea, but all UL listed NEMA outlets are perfectly capable of carrying their full load indefinitely, as the tests literally require them to draw 125% of their rated capacity until temperature stops increasing, and that temperature cannot be more than the temperature rating for the THHN/THWN wire they serve - typically 75C. This is a perfect example of internet forum conventional wisdom flat out getting something wrong and then stubbornly doubling down on bad information.

Yeah, that makes a lot of sense. It wasn't enough money to make me go down another research rabbit hole, which I suppose they basically count on.
