Hand Bending
Electrical conduit is a pipe or tube that protects electrical wires from accidental damage and exposure to the elements.

It is vital that electricians know how to bend and install conduits correctly. A properly bent conduit permits easy installation and provides a physical protection for conductors once the conduit is installed.

This module discusses the techniques for using hand-operated conduit benders.

Terms Associated with Hand Bending
Click on each term to find out more:

90-degree Bend
A bend that changes the direction of the conduit by 90.

Back-to-Back Bend
Any bend formed by two 90 bends, with a straight section of conduit between the bends.

Concentric Bend
90 bends made in two or more parallel runs of conduit with the radius of each bend increasing from the inside of the run toward the outside.

Developed Bend
The actual length of the conduit that will be bent.

Gain
Because a conduit bends in a radius and not at right angles, the length of conduit needed for a bend will not equal the total determined length. Gain is the distance saved by the arc of a 90 bend.

Offset
An offset (kick) is two bends placed in a piece of conduit to change elevation to go over or under obstructions or for proper entry into boxes, cabinets, etc.

Rise
The length of the bent section of conduit measured from the bottom, centerline, or top of the straight section to the end of the bent section.

Segment Bend
A large bend formed by multiple short bends or shots.

Set-up
Another name for the rise in a section of conduit. Also, a term used for conduit penetrating a slab or the ground.
