Conduit is a type of metal pipe electrical, cable or telecommunications wires are pulled through for neatness and protection. Make all necessary bends in the conduit before pulling the wires because the wires may become damaged when bending conduit. When pulling, have one person feed the bundle while another person pulls the wire bundle through the conduit to keep the wires feeding through the conduit without kinks.
Things You'll Need
- Cutting pliers
- Electrical tape
- Permanent marker
- White tape
- Wiring pull cord
Bundle the wires and secure with electrical tape approximately four inches behind the ends of the wires. Wrap electrical tape along the length of the wires at approximately three- to four-foot intervals to help keep the wires from shifting around when pulled through the conduit.
Stagger-cut the wires with cutting pliers on an angle to create an arrowhead shape at the end of the bundle of wires.
Wrap a piece of white tape around each wire and use a permanent marker to label each wire. Make sure the labels are dry before pulling the bundle through the conduit.
Make a slip knot about two feet from the end of the cable with wiring pull cord and secure with electrical tape. Tape the cord against the cables with electrical tape with the long end of the cord extending to the front of the wire bundle. Knot the cord in several locations along the leading end of the bundle of wires.
Wrap the first six inches of the wire bundle tightly with electrical tape. Extend the tape past the ends of the wires and onto the wiring pull string.
Push the end of the fishtape into the end of the conduit and continue until the fishtape comes out the other end of the conduit.
Wrap the pull cord around the end of the fishtape and pull the cord back through the conduit while retracting the fishtape.
Pull the pull cord to pull the wire bundle through the conduit with steady pressure.
Tips & Warnings
- Practice with short runs first to be sure you have the process down.
- Apply wiring lubricant for long runs or conduit with multiple bends to help reduce friction at the beginning of the run.
- Wear gloves if needed to reduce stress on your hands for long runs.
- According to local codes, certain wires and certain numbers of wires cannot be run through the same conduit. Consult your local building inspection office for regulations for your area.
