Here is my question: I am in Italy where the electrical system is 220v 50hertz. In the United States, we get 220v out of two ungrounded conductors. In italy, we get 220v out of one ungrounded conductors and one grounded conductor (neutral). What happens when you take an American type, two pole breaker and wire it to a European System? Where you would normally have two "hot" (ungrounded) conductors on both the line side and load side of the American type two-pole breaker; now you have one hot conductor and one neutral conductor wired to both the line side and load side of the American type breaker. Will the breaker still operate properly in case of a ground fault?

I hope this is a clear explanation. I also have picture but I don't know how to insert them into this e-mail.
