What is the distance multiplier for a 22 1/2° bend?

The distance multiplier for a 22 1/2° bend is 2.61. This value reflects how much longer the conduit will need to be in comparison to a straight run of conduit when accounting for a bend.

In electrical conduit practice, the distance multiplier is used to determine the total length added by bends in the conduit run. A 22 1/2° bend is a common angle used in installations and it has a multiplier based on its geometry and how much the conduit deviates from a straight path.

When calculating the effective length of conduit needed for installations that include bends, using the correct multiplier is essential. The distance multiplier is derived from industry standards which take into account the physical aspects of conduit bending, including factors such as the radius of the bend and the angle. This ensures that the total conduit length is sufficient to accommodate the bends while maintaining the necessary clearance and installation integrity.

In practice, when you have a series of bends in a conduit system, using the appropriate distance multipliers will help to accurately measure the length of conduit needed, accounting for the additional length introduced by each bend.
