The electric grid is three phase; 60 or 50 hz depending on where you are in the world. The voltage varies considerably, long distance transmission is in the kilovolts, or higher.
"split-phase 240V" happens at the transformer near your house, in North America. I don't know as much about the rest of the world, but I've always understood it to be ~440v split phase because it allows longer wires between the transformer and the house.

Where I live, we have three phase 480/277V for commercial. I believe that is standard in North America, but I'm not really sure.
- gwbas1c 2y agoOne of the reasons for the NACS switch is because light poles are ~270 volts, and NACS supports that voltage.
