How to Install Electrical Conduits

To prevent wires from being exposed to the outside world, local building codes require that electrical wiring is installed in EMT (Electrical Metallic Tubing) conduit, which is galvanized tubing that organizes electrical wires into a predetermined path. EMT terminates at electrical boxes that contain outlets, switches, light fixtures, or other electrical appliances.

Instructions

- 1
  Anchor the electrical boxes to the wall to determine the endpoints of the conduit.
- 2
  Add offset fittings to the electrical boxes by screwing them into place to allow the conduit to sit firmly against the wall.
- 3
  Determine the paths of the conduit and measure the conduit with a tape measure. Mark with a pencil and cut with a hacksaw. Remove the burrs from the cut end of the conduit with a deburring tool.
- 4
  Run the conduit and attach the conduit to the wall with either single-hole or double-hole straps and screws.
- 5
  Run a fishtape through the conduit path. At the end of the path, tape the end of the electrical wires to the end of the fishtape. Pull the wires through the conduit into place.
