... Should I remove the screw?But seriously...I was hanging a french cleat system in my workshop using 3" screws into the studs. After running a line of screws into the walls I realized a UPS was beeping. Breaker was ok but the GFCI on the first outlet in the circuit was tripped. (Brand new GFCI about 3 weeks ago, no trips prior to this) I tried to reset it and the breaker popped. Took me about 3.7 seconds to figure out I must have run a screw into the romex.With the circuit off I removed the screws then cut holes in the drywall at either end of the row of screws , cut the romex at both ends, pulled the bad section out though one of the holes. Yup - two screw holes right through the sheath.So my plan is to pull a new stretch of 12-2 back through the holes (pulled string through with the old romex so it'll be easier) and then install outlets at the two holes I punched in the drywall.But, as they say... if you want to hear God laugh, tell him you plans.Even after pulling the cable out and capping off the line side (have not pulled the new run yet) , the GCFI is randomly tripping. Takes from 5 minutes to 5 hours, but the thing will trip.All I could think of is that pulling on the line side of the romex could have moved wires in the receptacle just before the damaged section. When I tool the faceplate off I could see the ground was very close to the neutral terminal, but not touching. Close enough that I had to look from a couple different angles to be sure it was not touching. But it wasn't, and the trips are happening at random when nobody is in the workshop, not while the outlet is in use or being plugged in/unplugged. I pushed the ground wire further back in the receptacle and I'm hoping that the long delay is due to the small air gap allowing a minuscule amount of current to leak...Any other options? I have a spare GCFI outlet that I can swap into various position on the branch circuit (luckily I know the path it takes) and split the circuit in half and do a binary search, but that could take a long time... via /r/DIY https://ift.tt/2DvhL7c
