In creating a 10 inch conduit offset at 30 degrees, what is the distance between center to center bends?

When creating a conduit offset, the distance between the center of the bends is determined using a specific formula based on the diameter of the conduit and the degree of the offset. For a 10-inch conduit offset at 30 degrees, the correct calculation involves factoring in both the diameter of the conduit and the angle of the bends.

Typically, the distance between the bends (center to center) can be calculated using the formula:

Distance = (Distance between bends at 90 degrees) / 2 * (angle/ 90 degrees)

For a 30-degree bend, we would take the base distance associated with a 90-degree bend and adjust it. The base distance for a 10-inch conduit when making a 90-degree offset is generally considered to be about 40 inches (2 times the radius of a 10-inch conduit). Therefore, for a 30-degree bend, the distance becomes:

Distance = (40 inches) / 2 * (30/90) = 20 inches.

This calculation confirms that the distance between center to center bends for a 10-inch conduit offset at a 30-degree angle is indeed 20 inches. Hence, the option indicating 20 inches is correct for this specific scenario, reflecting the application of bending
