GFI down stream from a GFI

[Tom H]

Anyone know if installing a GFI on the load side of another GFI can cause problems.

[Doug Miller]

Why would anyone want to? If the first GFCI is wired so that it protects the entire downstream circuit, the second one is unnecessary -- and if it's not wired that way, then the two won't interfere with each other.

This usually happens when a GFCI protected appliance (pressure washer, boat lift etc) gets plugged into a GFCI protected outlet. It will work fine.

[DaveC]

I believe that GFCI is good for protecting only 6(?) outlets beyond itself. Can't imagine more outlets that that on one circuit, but that's the NEC (if memory serves).

Enjoy,

Got a citation for that? I can't find anything like that in the Code.
