EUROPEAN 220VAC DISCONNECT
EUROPEAN 220VAC DISCONNECT
(OP)
I'm in the middle of a discussion (read arguement) over the proper way to disconnect 220vac 1ph, in an electrical panel I'm designing to be installed in Italy. 220vac 1ph is being brought into my panel, which after going through a branch circuit protector, will be distributed to a series of dc power supplies. My question is, should I use a 2pole or single pole breaker for each of the power supplies? I'm thinking I need a 2pole breaker, but the other engineer believes I only need a single pole breaker. Won't I still have a potential of 110vac on the other leg if I only break one line of the 220? Could someone also point me to a place where I can find this info for myself?
Thanks,
Doug Greig

we had a similar application and we had to use a 2 pole breaker

There are a lot of regional variations, but European electrical service is typically about 400Y/230 volts, with 2-wire 230V circuits containing a grounded-neutral conductor. A 1-pole breaker may suffice, but that's subject to local codes, so only a guess.
