Type NM electrical cable is the most common type of electrical cable used in residential construction. It comes in a number of gauges and conductor counts, with 12-2, 14-2 and 14-3 being the most common. Romex® is a registered trademark of Southwire Corporation, manufacturers of type NM cable.
Type NM cable is not designed to be installed in conduit, although conduit is occasionally used to protect small runs of cable. Verify your intended use to meet the standards of the National Electric Code (NEC), and any local codes.
Type THHN and THWN wires are designed for use in conduit. This wire is made of individual multistranded conductors, rather than the single strand of NM. This makes them it easier to pull through conduit. Does this Spark an idea?
Instructions
1. Examine the conduit through which you want to run type NM wire. It will be very difficult to pull cable through conduit runs longer than 50 feet, or through more than one bend. You may be able to pull the cable through in sections for longer runs.
2. Insert your fish wire into one end of the conduit and push until it reaches the other end.
3. Strip the ends of the type NM wire, and make a secure connection with the hook at the end of the fish wire. Cover the connection with electrical tape to remove any sharp edges, which can snag the interior walls of the conduit.
4. Lubricate the wire with a wire lubricant. This will reduce the friction between the wire and the conduit.
5. Begin pulling the fish wire through the conduit. Having an assistant feed the wire into the conduit at the opposite end will reduce kinks and bends. Continue pulling until the wire is completely drawn through the conduit.
6. Remove the fish wire from the cable.
