220V is American version of what is known as 380V/400V elsewhere.
- ianburrell 2y agoUS three-phase power is mostly 208V, 240V, and 480V. The 208V is what normal residential 120/240V split-phase was made from. 240V is high-leg delta three phase and I think was old alternative to split-phase. 480V is used for light industrial that needs more power. There is nothing in US power system that is 220V.
