So I was pulling down the old ceiling in my kitchen to put in new lights. I found a junction box that was totally buried behind the drywall, with no cover plate. It had a bunch of wire nuts and splices just hanging out. I had to cut a hole in the wall to get to it and fix it properly. Turns out the last guy who worked on it just slapped drywall over everything. Now I'm paranoid about hidden junctions in old houses. Has anyone else run into this kind of thing? How do you deal with it without tearing everything apart?
Was called out for intermittent shocks in a kitchen remodel. Found the ground wire had corroded where it met the pipe. Cleaned it up and added a new clamp, no more issues. Curious how you all handle corrosion in older installations.
I get called back to jobs where GFCI outlets trip a lot. People just hit the reset button and ignore the real issue. What's the best way to explain why this is a bad habit?
