Every home in the US with an electric stove or water heater is using 240v electricity. It isn't really very exotic. 3 phase power to homes IS very exotic though and I'm not sure why it would be useful in homes.
- ssl-3 2y agoIn Norway, I understand that electric ranges are commonly cabled up with 3-phase wire that's about the size of a not-special extension cord here in the States. They accomplish this by using 400v. Meanwhile, also here in the States: The wiring for my very normal (240v) electric range is the size of a baby's arm and might be even stiffer. (That last claim may be a bit hyperbolic: I've bent at least my share of 6/3 wire, but I don't think I've ever bent a baby's arm.)
- UltraSane 2y agoThe 400v is the important part. Not common at all in US homes but is very common in US factories.

- UltraSane 2y agowhy? The benefits of 3-phase power are really only used by factories with lots of large electric motors. 3 phase has no benefit for resistance heating.
- korhojoa 2y agoYou can move more power per conductor with three conductors than with two. As a sidenote, my apartment has a 3x63A main fuse. Three-phase is everywhere here. Really convenient for ev charging too.
- UltraSane 2y agoDelivering 100 amps over 240 volt is not an issue.
