How to Run a Wire Through a Flexible Conduit

String

1). Tie a string to a long, thin nonflexible rod.
2). Push the rod and string through the conduit until the string emerges from the opposite end.
3). Tie electrical wires onto the string.
4). Pull the rod back through the conduit, bringing along the wires. This method works best for shorter pieces of conduit.

1). Tie a thin, heavy fishing weight onto the end of the wires with string or fishing line. Allow the fishing weight to have a 2 to 3-inch lead in front of the wires.
2). Place the fishing weight into the conduit.
3). Lift the end of the conduit higher than the weight, allowing gravity to pull the weight and wires through the conduit. Move along the conduit, lifting it, allowing the weight to slide and continuing until all wire is through. This method works best for vertically run conduit.

1). A fish tape is a thin, sturdy wire inside of a plastic housing and acts like a snake to move through conduit. The housing can usually be cranked to feed or reel in the tape. To start, feed fish tape through the flexible conduit until it comes through the opposite end.
2). Insert wires into the loop located at the end of the fish tape and twist wires securely onto the loop.
3). Pull the fish tape slowly and steadily while pulling the wire through the conduit.
4). Continue to pull the fish tape and wire through until the end of the tape attached to the wire exits the conduit.
