ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Will an American 2-pole brkr function properly if wired to a European 220v 50h sys ?

Came to think of something. The loophole is that a breaker listed for the American 240V corner grounded delta should be fine as well, as the voltage to ground is 240V in that case. I have no idea how common this is. Help from our American friends appreciated!
