How to Calculate the Bending of an Electrical Conduit


Calculating the bending of electrical conduit helps ensure you set up the most direct path between the source and the device. Conduit protects electrical wires to help prevent electrocution. It also mitigates the chances of the wire's insulation being damaged in a mechanical method. When installing conduit you are limited to a total amount of 360 degrees of bends. This assures, when you fish the wire through the conduit, it can be pulled through smoothly without damaging the wire.

Things You'll Need

  • Calculator
  • Determine the shortest path between the source and the destination for the conduit. Keep in mind, the conduit should be kept 18 inches from the ground while never bending more than 90 degrees in a single turn.

  • Draw the building roughly on a piece of paper and outline the desired path. Indicate on the drawing the intended number of degrees for each corner.

  • Add all of the corner's degrees together with a calculator. If the number is less than 360 degrees, start the installation. If it is more, you need to go back to the drawing board.

Tips & Warnings

  • Always turn off the power at the home's distribution panel for the wires you are working. Every household circuit has enough power to seriously hurt you.
