    3 Phase GFCI for portable tools

    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,

    Check Bender.org They have tons of GFCI and GFP options. I would not have thought that 5mA would be appropriate for this application but I do not know.

    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.
