I fell down the rabbit hole while housesitting for my parents, looking for electrical issues. Most seems pretty simple, like broken receptacles or ungrounded outlets. Some of the stuff I found was pretty appalling and I’ve done what I could to remedy it. I’ve found outlets connected to a ground wire but no ground. A lot was fixed with GFCI receptacles.
But when I tried to replace an ungrounded outlet with a GFCI outlet, for each hot and neutral I found two wires coming in that were soldered together and then wrapped with a ton of electrical tape in the box. It was basically one wire straight, then the other spiraled around with a copious amount of solder keeping them together, covered with electrical tape and then soldered to a short length of wire for connection to the receptacle. No wire nuts either. It didn’t bend and took up a lot of the box space. I tried to cut off as much as possible, then separate some lightly soldered parts trying to scrape off as much solder as I could. There wasn’t much room left, so I used about 6 inches of wire to connect the GFCI receptacle to a 3-port WAGO Lever-Nut. Two of the WAGO ports were populated by the wires that were previously connected by solder and electrical tape.
Those WAGOs have come in really handy where there was only a short length. I’m also not sure I need this many of these, but at the price I thought what the heck. I’ll save these for later. Right now my fingers are a bit raw for tightening so many wire nuts. I’m going to try the equivalent from Ideal. These ones are only 2-port, but they should be fine for my applications. I don’t get the price though, where this jar of 500 is less than a box of 150, sold directly by Amazon.

Some of the older wire is sheathed in paper or cloth. Was that a thing? Also, I’ve found 14 gauge wire but with ridiculously thick insulation.
