In ideal situations, you'll work with a conduit that still has old wire running through it. In these cases, you can simply attach the end of the old wire to the end of the new wire and use it as a pull wire, pulling the new line through the conduit If the pulling wire breaks when it is being pulled in the conduit, and if your fish tape is longer than the conduit, then you can insert your fish tape into conduit and push it until it comes out at the conduit end. Connect your cable to the fish tape, go to the other end of the conduit and pull your fish tape through the conduit Pulling wire through conduit can be tricky for electrical professionals.
