I have a concrete cutting contractor that requires a 3 Phase GFCI 20 amp for his portable wet cutting saw, he's using a gas powered generor for the supply. Is there such a device on the market that can trip out at 5ma?

Also can the GFCI work without a load neutral?
Thanks,

5mA isn't likely going to work, but it's probably not required either. There is a whole new class of GFCIs now for things like this, read this article and see which class of GFCI applies, then do a search for that class of GFCI. Most mfrs have released products now to fill this requirement.
 
Extension Cord

Extension Cord

I have the same question. I came across a portable machine, 3phase. 208v 20a extension cord that is ran outside the building. L15-20 twist lock extension cord, 100' long. 14-4 or 12-4 extension SJ cord. They wheel the machine outside on nice days, and cut material. Does this need a GFI ?

Is there a 3 phase GFI that will work with a motor starter?
