How to Install PVC for Electrical Wire

Save

Installing electrical PVC conduit to run wiring from a power source to an outlet is as simple as running the wire through each pipe and connecting them together. Electrical PVC conduit is a great choice for application around the house, as it is easy to cut and flexible to work with. Additionally, for underground projects it offers water tight seals and is rust proof, as opposed to metal conduit.

Things You'll Need

  • Measuring tape
  • Hack saw
  • Utility knife
  • 8 foot section electrical PVC pipe
  • Electrical PVC conduit cement
  • Metal fish tape
  • Electrical tape
  • 1 roll electrical wiring, 50 feet
  • 1 box electrical PVC lock nuts
  • Pliers
  • 1 box electrical PVC conduit clips
  • Measure the distance for the run of the electrical conduit to ensure you have the number of sections needed to complete the project. If the conduit will be installed underground, use the shovel to dig an 18-inch trench the full length of the installation.

  • Measure and mark the length of electrical PVC conduit needed for the project. Use the hacksaw to cut the conduit and then clean the cut end using the knife to deburr the conduit. If you need more than one section of conduit for a longer run, cut the pieces as needed to fit your project.

  • Tape the wires together and feed them through the section of conduit, pulling them out the opposite end. Attach the end of the conduit closest to the junction box, using a lock nut, and tighten it down using the pliers. If the conduit is run along the wall, attach a conduit clip to the wall using a screwdriver and screws included with each clip.

  • Attach the second piece of conduit to the first. Feed the wiring through the end of the second piece of conduit that has the flanged end and pull it out the other end. Apply the conduit cement to the end of the first piece of conduit and quickly insert it into the flanged end of the second to connect the two pieces of electrical PVC conduit together.

  • Repeat Step 3 to attach additional sections of conduit as needed until the conduit has reached the outlet and, using a lock nut, secure the end of the conduit to the existing outlet junction box. Attach the conduit to the wall as needed using the clips and screwing them into the wall. If the installation is underground, then use the shovel to bury the conduit with the dirt removed from Step 1.

Tips & Warnings

  • Avoid running electrical cable through electrical conduit that has the wires combined together in an insulated outer sheathing as this is an electrical code violation, leading to the possibility of the wires overheating and causing an electrical fire. Only use individual insulated wires to make the run.
