I bought a house recently. Some of the wiring, particularly in the basement, while not obviously unsafe, is... inspired.
On the side of a junction box in the basement, there's a device with two thin wires coming off of it, going up into a hole. I believe, but don't know for sure, that above the hole is an exterior wall, but there's nothing on that wall that would use such thin wires - just switches and outlets, which I'd hope are fed from the thicker cables also going through that hole.
So what is this thing?
