The power code in the US @ least is what the government says you have to do when wiring in order to pass inspection.
What about stoves, Warp? We have a duel-fuel range. It's got a gas cooktop and an electric oven. You want the gas on top for precision for heating stuff on top, yet the electric is better for the oven. It provides equal temperatures, unlike a gas oven. It needs a gas line and the 220/240 line. It's some gourmet thing.
Also, dryers. They use 220 to 240V.
