I just removed my kitchen soffit and found suspect wiring inside. It's a 100-year-old house with mostly knob and tube, but the kitchen was redone in the early 90s. Going through the house flipping on all the breakers and trying every switch we could find, nothing seemed to make current flow through this wire. We undid a massive amount of electrical tape to find that the junction looked like this:
So, it looks like the red and black are just.. hanging out, and the white goes to the knob and tube.
My questions are: *Is there ever a reason to do this? (This was clearly done intentionally, just trying to figure out why...) *If we wanted to cut these wires and cap them off inside the wall, is there any reason that would be dangerous?
We've never been able to make current flow through it, which makes sense now that we see that only one wire has been joined. Thanks for your help.
