What is required for an EMT run that includes 3 - 90s, 2 - 45s, and a Saddle bend?

In an EMT (Electrical Metallic Tubing) installation scenario involving specific configurations like 3 - 90-degree bends, 2 - 45-degree bends, and a saddle bend, the correct requirement is an Intermediate Pull Box. This is because the multiple bends in conduit can create limitations on the length of the run and make it difficult for pulling wires through the conduit without excessive force or compromising the wire insulation.

An Intermediate Pull Box helps to facilitate wire pulls by providing a point where the conduit run can be accessed and the wires can be directed smoothly. It is particularly beneficial in this scenario with the number of bends, as it would allow for easier navigation around the curves and minimize the risk of damaging the wires during installation.

Understanding conduit and wire pulling is critical in electrical practice, as there are limits to how many bends can be made in a single run without using pull boxes. By employing an Intermediate Pull Box in runs with multiple bends, the installation can adhere to electrical codes and ensure safe, compliant wiring practices.
