In that case, if you count/calculate like that, we even have 400V AC for our homes, here in Europe...
3 "hot" wires, 240V, 120° phase difference, each. Circular current. Usually coloured black, brown, grey.
One neutral wire. Usually coloured blue.
One PE "protective earth". Usually bi-coloured in yellow and green (green with a yellow stripe).
All five come directly from the power network supplier.
