From the basement, new NM-B (Romex) electrical cable is pulled up through the pilot hole and routed to the first sconce location. The old wiring is deemed too brittle for reuse. The new wire is then fed into the opening of the old electrical box. After pulling the wire, the old box is removed, and a new, larger electrical box (number 8) is installed in its place. This larger box provides more space for wire connections and is secured to the wall studs. This process is repeated for the second sconce location, fishing wire from the first sconce box to the second, avoiding unnecessary holes.
