On 5/19/2008 4:44 AM John Grabowski spake thus:

It is unusual to have so many GFI receptacles on the same circuit from the
original builder. In many cases one GFI would protect all of the
receptacles down stream. I have had a few customers think that they need to
change every outlet in a bathroom to a GFI and they wind up creating GFI
hell. They put three or four GFI's in series. When a ground fault occurs
in one of the downstream GFI's, one of the GFI's before it sometimes trips.
In that case the homeowner needs to go push the reset button on each GFI.

In that case (multiple GFCIs in a room), wouldn't it make much more
sense *not* to wire them in series, and just have each outlet protect
itself? What's the point of wiring multiple GFCIs in series?

That way, you'd know exactly which one tripped, and it wouldn't affect
any of its neighbors.
