Used for cosmetic and safety purposes, a PVC electrical conduit shields wires as they run down or behind walls and from room to room. The conduit is made from material similar to that of PVC pipe. It may encase the wires from, say, a track light to a wall outlet, or it may be installed behind dry wall to protect wires running to a junction box.

Cut the PVC conduit to fit the length from the electrical box to the next electric outlet or box. If there are bends in the route (like going down a wall and then turning to the right to run along the wall), measure each section individually and cut the PVC pipe to all of these lengths.
Group the wires together and tape the ends with black tape. Then slide a cable puller up through the first section of PVC conduit. Tape the wires to the end of the cable puller, then pull the wires through the section of PVC conduit. Use a long fibreglass cable puller made for this purpose.
Brush PVC adhesive around the outside of the conduit and push it inside the electrical box (or adaptor if one is being used). Then clip a PVC clip to the pipe and nail it to the wall frame. This secures the section of PVC conduit in place.
Attach the next section of PVC conduit. This section will be the first section of conduit that runs along the wall. You will need to install an elbow joint to the first section. Thread the wires through the elbow joint. Then brush PVC adhesive on the outside of the end of the first PVC pipe section and slide the elbow joint over it. Pull the wires through the next section of PVC conduit as you did for the first section of PVC conduit.
Continue to repeat these steps, attaching sections until you have routed the entire length of the wire run.
Tips and warnings
- Adaptors are used to connect larger outlets to smaller pipes, such as linking a 1-inch PVC conduit to an outlet on an electrical box that is 1.5 inches in diameter.
- Be sure the electrical power is turned off before you begin working with wiring in your home.
