Things You'll Need:
- Cotton ball
- High strength poly cord
- Electrical tape
- Wire stripping tool
- Wire lubricant
- Shop Vac
-
Step 1
Tie a cotton ball onto the end of the cord. Stuff the cotton ball and cord as far as possible into the empty conduit or pipe. Be sure you have enough cord laid out to get through the entire run of conduit or pipe and still have a foot or two hanging out of the entry point, and anchor the end so you won't accidentally pull it into the conduit.
-
Step 2
Go to the opposite end of the conduit or pipe. Start the shop Vac and put the suction nozzle over the end of the conduit or pipe opening. Put your hand over the nozzle where it meets the conduit or pipe to get the maximum suction. Let the shop Vac suck the cotton ball and cord all the way through the conduit or pipe.
-
Step 3
Return to the point where you anchored the end of the cord. Strip two inches of the insulation from the new wires. Tie the stripped wires together with the end of the cord, leaving about a foot of cord on the tag end of the knot. Double the stripped wires back against the insulated portions.
-
Step 4
Wind the tape around the knot and stripped wires, and continue wrapping the tape around the insulated portion of the wire and the tag end of the cord, taping them all together tightly for about a foot.
-
Step 5
Pull the cord steadily from the end with the cotton ball to fish the cord and wires through the conduit or pipe. It helps to have another person feeding the wire into the opening and applying wire lubricant so the wires and cord run smoothly through the conduit or pipe.
-
Step 6
Cut the cord and tape off the new wires. Strip the ends of the wires with the wire stripper and connect them to the terminals.
