Maybe a question for MNdrifter. Electricity is admittedly one of my weaknesses. Mostly having a Dad that was an electrician that I helped as a kid. That worked circuits live, way to much. I use rubber gloves to change the batteries in a flashlight now. But a Tesla has a 72 amp charger. Wouldn’t take 4 of your 20 amp breakers. If you have central air and electric range. Wouldn’t that be about 160 amps of your 200 amp service? That leaves 40 amps to run the rest of your house. God help you if you go all out for the 250 amp super charger. I know my 100 amp booster on my battery charger will run off a wall outlet. So maybe you can explain. Also, If half of a 50 year old housing addition. Put in another 100 or 200 amp panel. Would the service lines and transformers etc. handle that without replacing? With electrical wire and components at highest prices ever.
On another note. Had dinner with a 40+ year Chevy salesman friend. We were talking electric cars. Last word from GM to Volt customers. Don’t charge over 80%, and whatever you do. Don’t park it in your garage or near anything you don’t want burnt up. Till they figure a few things out.
