At the risk of exposing my ignorance-I'm trimming out others work-2-gang at sink counter fed w/12-3;cans were an after thought.pulled a switch leg into it-need other half for gfi-continues down wall 2-gang for fridge,then to low sg receptacle-power it up and the gfi trips-is it 2 hots W/ common nuetral that's the problem-switch fridge feed breaker off and it holds.
Sparky's correct. I found this out the hard way a while back while trying to catch a steam shower can light off the GFI and leave the rest of the bath un protected. Ended up just letting everything go through the GFI.
