How to Measure & Bend Conduit

Save

Correctly measuring and bending conduit makes the electrical installation process go smoother. Conduit is used to protect electrical wires in situations where it maybe exposed to damage. Common areas it is used are garages, wires outside wall systems and the exterior of the home. To facilitate the fishing of wires through the conduit, a single run should not have more than a total of 360 degrees of bends. Laying out an efficient path is the best method for a clean installation.

Things You'll Need

  • Measuring tape
  • Conduit bender
  • Determine the most efficient path for the conduit to travel between the two points. Keep in mind that conduit shouldn't be bent more than 90 degrees in one bend and can't have more than a total of 360 degrees in turns. It also needs to be 18 inches from the floor.

  • Draw a rough diagram of the wall and desired path of the pipe. Measure each straight section in the run and mark these lengths on the diagram. Indicate the desired angle of each bend on the drawing.

  • Measure the conduit from the start of the pipe to the first bend and mark with a black marker.

  • Place the pipe in the bending tool and and bend to the desired angle. Most bending tools are manually operated. Insert the pipe in the tool's clamps and pull the handle until it is the desired angle.

  • Double-check that the bend is in the right location by placing the pipe on the wall. Measure from the first bend to the location of the second bend and mark it. Repeat the process of making measurements and bends until the entire run of conduit is the correct shape.
