> To supply 3000W with a 110V supply would require around 28A, which will trip any 10A or 15A breaker commonly found on most house lines going to electrical outlets

The utter, utter majority of the world runs on something around ~230V [1], except America and Japan.

The US (and CA) runs on 240V as well, it's just split in half for smaller appliances. See requisite Technology Connections video:

My stove and clothes dryer are certainly not 120V.

In the same way that 240V countries run on 400V as well then?

Sort of. Outside of industrial or businesses, my understanding is that it is rare to see multi-phase power (400V) used in power applications. You may get 3 phases into your house, but the phases are used separately (each at 240V) for most things in residential.

Stoves are pretty much always at three phases unless it is something like a small summer-house

Washing machines too I've heard.
