How to Bend Conduit: 14 Steps
Conduit bending is an essential skill for any electrician or DIY enthusiast working with electrical installations. Properly bent conduit not only provides a professional appearance but also ensures the safe and efficient transfer of electrical wires through a space. In this article, we’ll outline 14 steps to help you bend conduit like a pro.
1. Determine the type of conduit: There are several types of conduit available, including EMT (Electrical Metallic Tubing), PVC (Polyvinyl Chloride), and IMC (Intermediate Metal Conduit). Be sure to choose the right one according to your project’s requirements.
2. Gather your tools: To bend conduit, you will need a conduit bender, measuring tape, marker or pencil, level, and a hacksaw or conduit cutter.
3. Measure and mark the bending point: Before bending the conduit, measure where you’d like the bend to be and mark it with a pencil.
4. Choose the correct bending angle: Common bending angles include 10°, 22.5°, 30°, 45°, and 90°. Decide which angle is appropriate for your application.
5. Position the conduit in the bender: Place the conduit in the bender groove with the marked bending point aligned at the arrow on the bender.
6. Adjust for spring-back: Due to its natural springiness, conduit will slightly bounce back after being bent. To account for this phenomenon, over-bend the conduit slightly by about 5 degrees.
7. Apply pressure on the bender: With one hand holding the bender handle firmly and your foot providing stability, apply even pressure until you achieve your desired bend angle.
8. Check for accuracy: Use a level or protractor to ensure that your bent angle is accurate before proceeding to subsequent bends.
9. Measure and cut the desired length of the conduit: Once you’ve bent the conduit, measure the correct length you need for your installation, and use a hacksaw or conduit cutter to trim off any excess.
10. Create additional bends as needed: If your installation requires multiple bends, repeat steps 3-8 until all necessary bends are made.
11. Ream the conduit ends: After cutting the conduit, ream the cut ends using either a reaming tool or the reamer attached to your conduit bender to smooth out any sharp edges.
12. Secure the conduit: Use conduit straps or hangers to hold your newly bent conduit securely in place according to your project’s requirements.
13. Install wiring: Carefully thread your electrical wires through the bent conduit, ensuring no snags occur that could damage the wiring.
14. Double-check your work: Inspect your completed installation for proper bend angles, secure connections, and neat appearance. Correct any issues before moving on to other parts of your project.
With practice and attention to detail, you’ll soon be bending conduit like an expert. These 14 steps provide a solid foundation for achieving professional-looking results that not only look great but also protect and route electrical wiring safely and efficiently.
