When making 15° offsets for EMT surface mounting between two equipment enclosures, what is the maximum degree of saddles you can make?

In the context of making 15° offsets for EMT (Electrical Metallic Tubing) surface mounting between two equipment enclosures, it is important to understand the function of a saddle in conduit bending. Saddles are the bends made in the conduit to facilitate changes in direction, while offsets allow for adjustments in height or location without increasing the overall length of the conduit run.

When conducting 15° offsets, the maximum allowable degree of saddles typically depends on the bending guidelines specified in the NEC (National Electrical Code) or given manufacturers’ standards. In this case, the configuration used for a 15° offset would not accommodate saddles that are effective or legal under standard practices, hence the correct response reflects that there should not be any saddles made.

Therefore, the reasoning for selecting "None of these" is that creating saddles in conjunction with a 15° offset does not comply with the operational or safety standards required for EMT installations when viewing allowable practices. It emphasizes the importance of adhering to industry standards to ensure safety and compliance in electrical installations.
