Types of Conduit Bends: A Complete Guide for Electrical Wiring

Types of Conduit Bends

Conduit bends are essential in electrical installations to route conduit around obstacles, make turns, and provide a clean and organized pathway for electrical wiring. Different types of conduit bends are used based on the degree of the bend and the specific requirements of the installation. Here are some common types of conduit bends.

1. 90-Degree Bend

A 90-degree bend is the most common type of conduit bend and creates a right angle turn. It is typically used to change the direction of conduit around corners or obstacles. This bend is achieved by bending the conduit to a 90-degree angle using a conduit bender or by using pre-made 90-degree elbow fittings.

2. 45-Degree Bend

A 45-degree bend creates a gentle angle of 45 degrees in the conduit. It is often used when a less sharp turn is needed or to maintain a smooth conduit pathway. This bend provides a gradual change in direction and is commonly used to navigate around obstacles or create a more aesthetically pleasing installation.

3. Offset Bend

An offset bend is used to shift the conduit sideways in a vertical or horizontal plane to avoid obstacles or maintain alignment with other components. It involves two 90-degree bends in opposite directions, with a straight section of conduit in between. Offset bends are commonly used when conduit needs to be moved around structural elements or other conduits.

4. Kick Bend

A kick bend, also known as a back-to-back bend or saddle bend, is used to change the elevation or height of the conduit. It involves two 90-degree bends in the same direction, creating a U-shape in the conduit. Kick bends are often used when routing conduit up or down a wall, allowing the conduit to exit the wall and continue in the desired direction.

5. Three-Point Saddle Bend

A three-point saddle bend is used to support the conduit by creating three points of contact with a surface or structure. It involves two 45-degree bends and a straight section of conduit in between. The bend creates a U-shape with two downward-facing “legs” and a center section that rests on the surface or structure. Three-point saddle bends are commonly used when conduit needs to be supported on a wall or ceiling.

6. Rolling Offset Bend

A rolling offset bend, also known as an angled or parallel offset bend, is used to change the direction of conduit in both the vertical and horizontal planes. It involves two sets of 45-degree bends in opposite directions, with a straight section of conduit in between. Rolling offset bends are often used when navigating around obstructions or when conduit needs to be aligned with specific entry or exit points.

Conclusion

Conduit bends are crucial in electrical installations to route conduit effectively, avoid obstacles, and maintain the integrity of the wiring system. The various types of conduit bends, including 90-degree bends, 45-degree bends, offset bends, kick bends, three-point saddle bends, and rolling offset bends, offer flexibility in adapting conduit pathways to specific installation requirements. Properly executed conduit bends ensure efficient wiring, smooth conduit runs, and adherence to electrical code standards.
