Electrical Bends: How Many Are Allowed by the NEC®?

What combination of electrical bends is allowed by the NEC®?

a. Single bend

b. Double bend

c. Triple bend

d. Quadruple bend

Answer:

The NEC allows a combination of bends between pull points as long as the total does not exceed 360 degrees.

Explanation: In the context of the National Electrical Code (NEC®), which sets the standards for safe electrical design, installation, and inspection to protect people and property from electrical hazards, there are specific rules for the number of bends between pull points in a conduit run.

According to the NEC, the total number of bends between pull points should not exceed 360 degrees. This means that the combination of bends such as a single bend, a double bend, or a triple bend could be allowed, as long as their cumulative total does not exceed 360 degrees. A quadruple bend could also be acceptable if the total of all bends remains within this limit.

It is essential to avoid too many bends to ensure that wires can be pulled through the conduit without excessive difficulty, which could potentially damage the wires.
