No post this morning because I was busy yesterday. It was time to fix the tripping breaker problem I was troubleshooting a few days ago. If you will recall, I had a problem with the breaker tripping repeatedly for the receptacles in two of our bedrooms: one was use as a guest room, and one that we use as an office/sitting room. It turned out the wire running from one receptacle to another, even though it was disconnected from everything, was only measuring 2 ohms between the neutral and ground wires. That will trip the breaker (GFI) every time. It was probably caused by a staple, nail, or nail plate rubbing through the insulation on the wire.
I isolated the bad section by cutting it out of the upstream box, which of course orphans the downstream box. The breaker reset once I did that, but now I have a dead receptacle. The dead plug is the one on the left. (I took pictures of my entire house while it was under construction, before they put the drywall, insulation, and vapor barriers in. That really comes in handy. I know where every stud, wire, pipe, and duct is)

There is no way to fix that shorted Romex, the wire must be replaced if we want that plug to ever work again. The bad news is the receptacle before the bad wire is on one wall, and the receptacle after the bad wire is on another: the Romex goes around a corner. That is going to be nearly impossible to do without tearing out a lot of drywall.
The good news is there is a dedicated receptacle on the same wall that I could tap into. You can see it on the right side of the above photo, it’s the one supplied by the yellow Romex. It’s the only receptacle on that 20 amp circuit, so I can just add the orphaned plug to that. Since it’s a 20 amp breaker, I can’t use 14 gauge wire, so I went to Lowe’s and got 25 feet of 12/2 wire bright and early in the morning.
I cut two holes in the drywall, about 8 inches beneath each receptacle. I also had to notch out that furring strip you see on the right. Once I did that, you will note that there is a straight, unobstructed path between those two points and pulled Romex through the intervening space, because the only one of the furring strips goes all the way to the floor.
Now I have a wire running from one to the other, but the boxes are recessed into the concrete blocks. I fixed that with a hammer drill to put a 3/4 inch hole in the concrete block 8 inches below each box. Now it was a simple manner of pulling the ends of the wires through the hole, up through the bottom of the box, and wiring everything in.
I still needed to notch the furring strip in this photo:

A bit of drywall patching. I like using the color changing mud, because it’s so much easier to tell when it’s dry. It leaves a flat looking spot on the wall that clashes with the orange peel finish, so once it dries, I sand it smooth before mixing some of the mud with some water to thin it to about the consistency of waffle batter. Then I roll it on with a foam roller, and it makes a pretty convincing orange peel surface.

Then test the plugs. All done. The entire fix, including a 2 hour trip to Lowe’s ate up my Saturday. The wife will paint the patches, once the mud dries. Painting his her territory.
