I'm living in apartment block built in 2016 in eastern EU and here every apartment has a separate 3 phase(5 pin) socket for the stove. It is a 7kw beast, it can easily destroy regular aluminum-steel pan if you put it on max heat. Steel part will fall apart.

Same in Eastern Germany, at least up to the 2000s. (Probably still, but I left, so can't vouch.)
