    Hey Jerry, can you have 2 GFI's on one circuit. I understand as no but was just told differently today.
    Can you cite the NEC ref?

    There is no NEC reference to provide as a one is allowed to have as many GFCIs 'daisy-chained' together as one would want ... except that, if I recall correctly, some manufacturers limit the number of downstream receptacles from a GFCI receptacle to a maximum of 10 - or at least some did that years ago.

    The only problem that can cause is that one would need to find the GFCI which tripped off because the most sensitive GFCI will trip before a less sensitive GFCI will trip.

    If one wants each receptacle downstream to have its own GFCI protection (someone like me) then do as I did ... wire each GFCI receptacle as bypass instead of pass through, that allows only the GFCI seeing the fault to trip, none of the other GFCIs will trip off.
