Want to add that my own home is a townhouse condominium with 100 amp service, 240v for clothes dryer and central A/C, and natural gas for furnace, hot water, and stove. I added a 240v. 40 amp (#8 wire) circuit to the garage for a Clipper Creek HCS-40 to get the full 27.5 amps/6.6KW the leaf would draw. Adding that circuit maxed-out the electrical panel and doubt it would be possible or advisable if had either an electric stove or electric hot water heat in the mix. I am able to run the A/C, clothes dryer and charge the car simultaneously without tripping the 100 amp main breaker. My own daily usage of a 24 KWh leaf was relatively heavy (100% to LBW/VLBW for a 75-mile daily commute), which was @ 20 KWh/day usage, which roughly double the electrical load on the home's electrical service.NoReleaf said:Thanks, Goldbrick. You've prepared me well to ask an electrician. FWIW, yes to electric water heater and electric dryer (not on the circuit used for the EVSE). Forced air gas furnace and gas range. No other heavy loads that I can think of. Oh, a space heater because of the ill-conceived central "heating." That's a bit of a load. Also not on the EVSE circuit.
I'm starting to think (again) that this house has all it can handle without expensive work, but I'll find out what it will cost to have someone come out and tell me that.
So as Leftiebiker recommended, you might need to consider a 240v-L2 evse that is slightly constrained in peak electrical draw. The key difference while charging the leaf is getting roughly 2/3 the peak amperage during the 0%-80% of battery capacity. After @ 80% full, the car's control system will ramp-down the amperage draw to less than the constrained evse is capable of delivering so there will be no difference in charging time for topping off the battery.
