What is the angle of a bend that has a total offset of 15 inches when using a 30° bend?

In the context of raceway bends, the angle of the bend is determined by both the radius of the bend and the total offset that needs to be accommodated. A 30° bend is defined as having an angle of 30 degrees, which means that for every 15 inches of offset calculated, the design will rely on the properties of such a bend.

Given that the total offset is stated to be 15 inches and the chosen bend has an angle of 30 degrees, this configuration directly correlates. The offset of 15 inches aligns perfectly with the characteristics of the 30° bend, which anticipates this specific distance based on its geometry.

So, the proper interpretation here is that the total offset of 15 inches indicates that a 30° bend is the appropriate solution to achieve the desired direction in a raceway system. Other angles, like 45°, 60°, and 90°, would result in different offset distances that do not match the constraints given in the question. Thus, the choice indicating a 30-degree angle is entirely appropriate for a 15-inch total offset.
