Techniques for Bending Electrical Conduit

Bending electrical conduit requires precision and the appropriate tools to ensure the conduit maintains its integrity while fitting the intended pathway. The most common types of conduit used in electrical installations are rigid metal conduit (RMC), intermediate metal conduit (IMC), and electrical metallic tubing (EMT). Each type requires slightly different handling and bending techniques.

Before beginning any conduit bending task, always measure the required bend angle and length accurately. Mark the conduit at the point where the bend will start to ensure precision. Here are the key techniques for bending conduit effectively:

  • Using a Conduit Bender:
    The most widely used method for bending EMT and thin-wall conduit involves a manual or hydraulic conduit bender. Position the conduit in the bender with the mark aligned with the bender’s arrow or reference point. Apply steady pressure to create the bend while frequently checking the angle with a protractor or angle finder.
  • Heat Bending:
    For rigid metal conduit, especially thicker types like RMC, heat bending is occasionally used. This involves heating the conduit with a torch to soften the metal before bending. This method requires specialized safety precautions and is less common in typical electrical installations.
  • Spring Benders:
    For smaller diameter EMT conduit, spring benders can be inserted inside the conduit to prevent kinking while bending by hand. This is effective for gentle curves and small bends.
  • Using a Pipe Bender for RMC:
    Rigid metal conduit requires a heavy-duty pipe bender. Align the conduit with the bender’s shoe and apply force carefully to achieve the desired angle. Due to its thickness, RMC bends are less frequent and often pre-fabricated.

Common Bend Types and Their Applications

Understanding the types of bends and when to use them is crucial for effective conduit installation. Each bend type serves a specific purpose in navigating obstacles and changes in direction.

Bend Type Description Typical Use Recommended Bend Angle
90-Degree Bend A sharp, right-angle bend to change conduit direction vertically or horizontally. Corner turns, directional changes around walls or ceilings. Exact 90°
Offset Bend Two bends in opposite directions to shift the conduit path laterally without changing direction. Navigating around obstacles like beams or pipes. Typically two 22½° to 30° bends
Back-to-Back Bend Two consecutive bends forming a “Z” shape to adjust conduit height or clear obstructions. Elevation changes, bypassing obstructions vertically. Two 30° to 45° bends
Stub Bend A short bend used to extend the conduit a few inches from a wall or box. Connecting conduit to electrical boxes or enclosures. Typically 10° to 15°

Tools Required for Bending Electrical Conduit

Having the correct tools is essential to perform accurate and safe conduit bends. The choice of tools depends on the conduit material and diameter.

  • Handheld Conduit Bender:
    Designed specifically for EMT conduit, this tool often includes degree markings and a shoe for precise bends.
  • Hydraulic Conduit Bender:
    Used for larger diameter or thicker conduits such as RMC, providing greater leverage and consistent bends.
  • Conduit Bending Springs:
    Inserted inside the conduit to maintain shape during hand bending of smaller diameter EMT.
  • Measuring Tools:
    Tape measure, protractor, angle finder, and conduit markers are necessary to mark bend points and verify angles.
  • Pipe Cutter or Hacksaw:
    To cut conduit to length before bending.
  • Personal Protective Equipment (PPE):
    Gloves and eye protection to prevent injury from sharp edges or metal shavings.

Step-by-Step Process for Bending EMT Conduit

The following is a detailed procedure for bending EMT conduit using a manual conduit bender:

  1. Measure and Mark: Measure the length to the bend location and mark the conduit with a permanent marker at the start of the bend.
  2. Position the Conduit in the Bender: Place the conduit into the bender’s shoe so that the mark aligns with the bender’s arrow or bending indicator.
  3. Align for Proper Bend: Ensure the conduit is properly seated and held firmly. The handle should be perpendicular to the conduit for a 90° bend.
  4. Start Bending: Pull the handle steadily downwards, applying consistent force. Stop frequently to check the bend angle with a level or angle finder.
  5. Check and Adjust: Once the desired angle is reached, release the bender and inspect the bend for accuracy and smooth
