american electrical code has so much of weird shit that would be illegal out there, it’s dazzling. you can’t get three-phase power as a regular customer, but you can as an industrial, but only as 480V interphase. there are like 7 different mains voltages available. it would be illegal in europe to come up with something like “high-leg delta” but it’s a thing out there
