Hello. I'm new here. This looks like a great forum.
The "peek in the panel" picture reminded me of the day I looked at this house we retired to. This is an "owner-builder" home. The builder, a nice enough guy, was not the greatest craftsman. After we toured the poperty and looked through the hose, I looked in the service panel just for drill. I was surprised to see no 15 amp breakers!
We made a bid on the place, which was significantly lower than the asking price, as I knbew there was a lot of things to be done to make it into a place i wanted to live in. To our surprise, we got it! The day it closed escrow, I was here with my work truck. Pulled the panel cover, and lo-and-behold NO #14 wire in there! All those 20 amp breakers had #12's stuck in 'em! Muust have been a good sale on 12-2 NM that day!
Over the next day and a half, I pulled every device out of it's box, took out all the backstabs (oh, yeah) and pigtailed everything, corrected the GCFI wiring, straightened out the travelers ona ll the 3-ways, and "got 'er done". Been here ten years now. STILL fixin' things, but they ain't electrical!
