Daisy-chained electrical outlet circuit tracing complexity

“Should I leave the neutral disconnected when replacing a smart switch with a conventional switch? My home has switches from Deako, which are a proprietary quick-change style switch with various dimmers and wifi enabled upgrades available. I'm replacing one with a regular Leviton Decora rocker switch. This is a single switch that controls a single light (the pantry). When I removed the Deako box, I found 4 wires labeled hot, load, ground, and neutral. I swapped in my Leviton Decora rocker switch ”

“Help connecting vintage medicine lighted cabinet with built in outlet I purchased a (mostly) working vintage lighted medicine cabinet a couple years ago pulled from a time capsule home somebody was destroying... I mean remodeling. I restored it recently, including new internal wiring and a fluorescent to LED bulb conversion, not for aesthetics, I actually like the hum and flicker of CFL tubes but the ballast on one side was busted and modern ballasts I found were too large for the compact space ”

“Removing daisy chained outlets; how to properly restore the chain? Problem I am removing two outlets for occupant safety reasons. I have already removed both outlets and capped all wires found within. But now, when I turn the breaker back on, one outlet comes back, but the ceiling light doesn't receive power, and that's bad. So now I think they were probably daisy chained to each other or to other outlets in the same room. One outlet was partially switched. The other wasn't. I've completely remo”

“How can I run cable for an outlet behind a brick fireplace wall? I am looking to add an outlet above my mantel/fireplace. The fireplace is a single layer of brick spanning from one wall to the other, built in front of a 2x4 wall, so there is a void behind it in the 2x4 wall. The problem is that I think a concrete pad was poured under the brick facade so I can't access the wall void behind the facade from the crawl space. There are bricks on the top of the foundation and in front of the wall void”

“Very old wire identification for replacing an old receptacle I am ready to replace an old receptacle by a new one. Pictured is the old bugger. It is 15 Amp, not clear when it was installed, but the wires seem to have cloth insulation and you cannot tell color of either of them. It has been some time since I changed a receptacle and I swear I do not remember seeing 4 wires; I remember only two per receptacle. So I took off the two wires from the bottom (A and C), and B and D are still in place. A”

“What part of this do I have to remove to pull this window out? I am rehabbing this house which needs some windows. I'm currently working in what I assume was a studio room since it vaguely stinks and is absolutely covered in corkboard, on the floor, ceiling, and walls. I was removing the corkboard from the wall, and it was covering up this window frame. The window frame itself is a bit rotted, and the glass is broken, so it has no insulation value left. I want to replace it. Theres also conspicu”
