A run of EMT with offsets and saddles involves a total of how many degrees of bends?

To understand the total degrees of bends in a run of EMT (Electrical Metallic Tubing) with offsets and saddles, it's important to know how much each type of bend contributes to the overall angle.

Offsets are typically used to adjust the conduit path to go around obstacles or align with connection points, and they usually consist of two bends that each contribute to a standard angle – most commonly 30 or 45 degrees, but this can vary based on the specific requirements of the installation.

Saddles are also used to create a change in direction and require three bends to form their shape. The total degree of bends for a saddle typically adds up to a common degree rating which may be around 90 degrees due to the three bends used to make one complete saddle connection.

When you calculate the total degrees by summing the bends from both offsets and saddles, it can vary widely based on the number and type of bends used. However, if the options provided do not accurately correspond to the total calculated degrees from common practices or specific configurations involving offsets and saddles, then the answer would be 'None of these.'

Thus, without an exact match in the provided numbers as a result of common configurations, the conclusion is that 'D' reflects the fact that
