Potential for electric Tesla type class B?

[Davydd]

In the house I designed and built and lived in for 34 years I had a total of 500 amps over three separate panels - 200 amp general to the house, 200 amp for electric resistant floor heat over 2,400 sf in the house and 100 amps to a detached garage. It was an all electric home with no gas. I think our biggest draw was our water heater. Being super insulated, passive solar and heat sink mass (concrete floors and heavy timber frame) the house was near zero energy and we didn't use that much electricity for heat. Radiant heat was great for comfort.
