I'm confused here. Are you still talking 120v? If I'm not mistaken, by the NEC, a 30a 120v circuit would have to be a dedicated circuit with a single 30a (NEMA 5-30 or 6-30) receptacle on it. Not that that's impossible to have such a circuit, but I can't imagine what normal domestic purpose it would serve. Any home appliance that requires that kind of power is almost always a 240v appliance. I've NEVER seen a 30a 120v circuit in a garage here in Ohio. Heck, I don't think I recall ever seeing one in a house, either, though I have seen them in commercial settings. However, I HAVE seen countless 30a 240v dryer receptacles and 50a range receptacles in homes and garages. The latter are often used for an arc welder. Maybe that's what you meant? > Anything much older than [the Carter Administration] and it's going to > have to be re-wired anyway to be brought up to code. Your building authority must be pretty strict there. Around here, even the oldest houses are acceptable, no upgrades required at sale, as long as they met code when they were built. Heck, a guy I knew bought a house in the 1980s; it still had the original 120v only, 2-wire service with 4 fuses in the panel! Now, if you change something - even just moving a receptacle - THEN you have to bring that portion of the wiring up to code. Depending on the situation, that can sometimes trigger a major wiring project. FWIW, I've charged EVs at a home built many years before the Carter Administration (1959). The main panel was rated 100 amps. It had enough capacity to easily support an extra 240v 20a circuit. Even a 60a service would probably suffice for an EV if you didn't try to also use too many other large electric appliances (aircon, water heater, range, dryer).
