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 ?

Hi Sparky
I would be inclined to reiterate what Paul has said, but also:
Is US breaker rated for use on 50Hz 220V to ground?
Do US breakers have tripping characteristics in accordance with EN 60898 (IEC 60898), EN 60947-2 or other standard that may be required for Italy?
I would be inclined to fit a European breaker to ensure compliance. I would also seek local advice regarding RCD (GFI) requirements. As Paul stated the supply may be TT, requiring such a device for ground fault protection.
These questions can only be correctly answered by someone with local knowledge.
Good luck with your installation.
