Major breakthrough on nuclear fusion energy

EU is on 50hz AC, where as the US is on 60hz. It would work fine for purely resistive appliances, and possibly devices with switching mode power supplies, but some devices would be unhappy plugging in to the wrong frequency at 220V.

I'm not sure about the phase alignment but that may be an issue as well. US is split phase, but Europe has 220 on a single conductor?

it's 230 (+-10%) nominal not 220. At my house it's around 235. It's 230v phase/live to neutral and 400V between live wires in 3phase. Nowadays 3-phase (120degree between each) is a commodity.

In my part of USA the typical voltage between the two sides of a breaker box is 240V. It actually moves around a bit below that value, but doesn't seem to ever exceed 240V. I think most consumer devices have the circuitry necessary to survive such variation, but I have seen some (expensive) professional equipment fried in an instant...

Thanks for that. Sounds wonderful compared to the typical 200 amp, split phase service we commonly have in the US.

How many non-switching power supplies will care either?
