Default 3 phase 240v breaker
I have a piece of equipment at my facility that is 240v 3 phase and it broke. We had the service guy in and he was suprised we didn't have it on a GFI it is on a regular 3 pole breaker. I had never seen a 3 pole GFI breaker he said their kind of pricey. It's a Square D Qo panel has anyone come across this or knows where I can get one?

What kind of piece of equipment are your talking about?
I really see no reason to put machinery on a GFCI.

It is plate maker it makes printing plates and has chemical reservoirs and heaters. I didn't get to talk the service guy all I got was a email after the fact and now I have pick up the pieces, but I'm sure you all don't run into problems like that.

It seems as though you may have met a "technician" and not a real electrician.

Are you asking about GFP or GFI?

thank you wildleg your links pointed me in the right direction but with all the cost cutting and belt tightning going on around here it probably ain't gonna happen.
