>>8748The house receives 240v split phase from the street which is split to 120v. Low power devices can be run at 120v 10a while high power devices can run at 240v 50a. The efficiency loss due to running at a lower voltage inside the home is near zero. You can easily wire another 240v outlet if you need one. Compare to the dumbass britbong system where they didn't have circuit breakers or fuse boxes for the house and are stuck putting fuses in individual plugs and using fuse wire (picrel) which is the stupidest thing ever invented because someone is just going to replace it with regular wire instead of fuse wire and start an electrical fire.
Europlug only runs at 250v 2.5a or 625w max. Standard NEMA takes 120v 15a or 1.8kw.
