Home Charging Station help for a new owner

[NeilBlanchard]

Going higher on the wiring / breaker is for allowing for higher charging rates in the future.

Right, but it won't matter unless the car's onboard charger is upgraded too. Chevy put a 7.2 kW charger in the Bolt, so I take that as an indication that despite having larger batteries, chargers will be stuck at that amount for a while. Or perhaps there's regulatory or safety reasons to not go higher than that in home and residential environments.

I am talking about future EV's with 10kW chargers, etc. The Class B Electric has a 10kW, and Tesla has twin 10kW as an option.

My late B charged at 40A at 240v. That is not 10K. Most commercial chargers limit the current to 30A and the voltage is 208VAC. A wye with 120VAC available (most commercial installations) only has 208V available. It is rare to find commercial 240V.
