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.

The charger breaker should be in a separate heavy duty pony box, not a breaker on the main box.

Codes are way behind what they need to be for EV chargers, people are putting in 40A high duty cycle circuits on the cheap. That's a lot of energy flow when things start arcing.
