I have a ceiling junction box in my garage that has four armored cables coming into it. I want to remove one of the cables as I'm not using it. I don't have access to the back side of the box, because the ceiling is finished (metal lath and plaster).
I'm thinking I could remove this a few different ways:
- twist the wires together, wire nut, and leave in the box
- cut the exposed copper, and electrical tape the ends
- cut the wires back to the cable clamps
