Title: Lab 13-3: 90° Bend and 90° Back Bend - 1 Hour
Course: Basic Electrical Theory and Wiring (Sandbox) > Section: Module 13: Conduit

Introduction

Now that you've completed your saddle bend, you will do a 90° bend. The 90° bend can be used to make 90° angles, go around corners, or make turns to enter into a control panel. The 90° back bend is useful if you have to put conduit within a specific space. For example, if you were trying to have conduit come out the bottom of one control panel and enter into the bottom of another control panel, you would use a 90° bend to come out of the first panel and then the back bend to enter back into the next panel.

The video will show you how to do this.

Instructions

1. Follow the guidelines on the Lab Expectations page.
2. Obtain the conduit from your previous lab.
3. First, we will do a 90° bend.
  1. Measure 1 inch from the end of your conduit and mark the conduit with the marker all the way around the conduit as shown in the video.
  2. Insert the conduit into the bender, align the 1-inch mark with the arrow on the bender, and bend the conduit to 90° as shown in the video.
4. Second, we will do a 90° back bend.
  1. From the end of your 90° bend, measure out 33 inches and mark the conduit all the way around the conduit as shown in the video.
  2. Insert the conduit into the bender, align the other 33-inch mark with the tip of the star on the bender, and bend the conduit to 90° as shown in the video.
  3. Straighten conduit.
  4. Measure the overall width of the conduit with a tape measure. It should be around 33 inches.

 | Your conduit may be kept as a souvenir or thrown in the garbage. |
