For a 15° saddle installation, what would be the total bends when using four such saddles?

When dealing with saddle installations, it's important to understand how the angles of the saddles influence the overall bends formed in the conduit. In this case, each saddle has a bend angle of 15°.

To calculate the total bends created by four saddles, you simply need to multiply the bend angle of each saddle by the number of saddles used. So, for four saddles at 15° each, the calculation would be:

15° (per saddle) x 4 (number of saddles) = 60° total bend.

This total of 60° represents the cumulative bend angle formed by the four saddles in the installation. Understanding this concept is crucial because it helps in planning and ensuring that bends remain within allowable limits as per electrical codes and standards. This calculation is foundational in electrical layout design, ensuring that installations follow best practices for conduit bending and routing.
