Found a nest of wires that had been sitting wrong for 6 years in a Chicago condo
Went to swap out an old DSC panel in a building from 2018 and behind the drywall was a tangle of cat5 and 22/4 that looked like a bird did it. How many of you actually label every wire from day one or just figure it out as you go?
Yeah, the "labels facing inward against the back of the box" thing hit me hard. I had a similar mess in a remodel where someone used those stick-on flags and they all got caked in drywall dust and fell off before I even got the panel mounted. Had to tone out every single pair with my probe, took me half a day for what should have been a two hour swap. The heat-shrink labels sound like a lifesaver, I usually just write on the jacket with a sharpie but that stuff fades too eventually.
Labels are great until you're in a pinch and the drywall is open for a week. What people don't talk about is how the drywallers or painters often just shove everything back in after they finish, then the labels get torn or wrapped around a stud. Had a job once where every single wire was labeled but the labels ended up facing inward against the back of the box. Had to pull every one out and re-label them anyway. Real trick is using a label maker with heat-shrink tubing, not the stick-on flags that fall off after a season.
