Large appliances (water heaters, furnaces, ovens, heat pumps/air conditioners, clothes dryers) typically use 240v and have dedicated circuits but yeah, everything else is 120v.
so a house with 120v@200A will have a capacity of 24kw. I am really curious about how is that divided between heating devices. I can tell already 7-11 kw will be dedicated for EV charging if existed
It’s closer to 48kw. North American (residential) power is weird. lol.
We use what’s called split phase where basically you have three wires coming into your electric panel: two “hot” ones each carrying 120v and one ground.
The breaker box is staggered so that every other slot is powered by one or the other 120v inputs. To get 240v for large appliances, we use big, double-breakers which connect both of the 120v inputs together.
The rest of the 120v circuits are staggered across the two 120v inputs. e.g. If one of the two “hot” cables was disconnected, roughly half the outlets in your house would still work.
do americans use 120v ? if yes even 200A is barely enough. where i live we use 220v@60A. Anything beyond a tri-phase meter and a permit will be needed

48kw just for residential! hell that is alot!
It is but thankfully most people never use anywhere near that much (at least, normal people lol).
yea cause that sounds like industrial scale capacity!
nonetheless, it helps to have a thermally isolated residence to avoid warmth dissipation
