Thanks for the thorough
Thanks for the thorough analysis John. It does look at bit scary as you have laid it out however. I had my 240V EVSE installed 8 years ago and at that time it cost me $500 for the EVSE (which were more expensive then) and $500 for an electrician to wire it up. I happened to have a 200Amp service, but my slower charging rate only needed a 20A breaker, and I did happily have space in my electrical box. My electrical water heater actually uses the most power for me currently (8kW), and the clothes dryer uses 5kW, where my EVSE uses under 4kW. Now a newer EV will probably draw twice that much (7.7kW), but it still shouldn't need more than a 40A circuit. In fact doesn't the 2022 Bolt EV/EUV come with a free install of a NEMA 14-50 outlet and supply all of the materials including a new 40-amp circuit breaker through Chevy's partner Qmerit?
