at one time it was common practice to solder wire connections and then tape them, instead of using wire nuts, the last and only time i did this was on one government subsidized housing complex 46yrs ago
Is this what your talking about?
I recently did a bunch of electrical repairs on a house that was probably built in the late 50's or early 60's. It had connections I had never seen before. They had stripped the wire in the middle of its insulation and twisted & soldered another wire to it. After this odd splice, there was a bit of insulation and then the wire was stripped again and connected to the switch or outlet. The "splice" was wrapped with electrical tape. AT first I thought this was a home-owner hack but I found them all over the house and in area's I don't believe anyone had ventured.
It was strange but sound. Never the less, any time I had to work in one of those junction boxes, I brought it up to modern specs.
