> Every US household has at least some big circuits across both lives. Not really. My parents have all natural gas for the furnance, oven, stove, clothes dryer, and water heater; no air conditioner. Everything else is lights and outlets. There are no 240v outlets and no 240v breakers other than the main breaker.
