Exciting Electrical Conduit Bends Challenge!

What is an acceptable combination of conduit bends between pull points?

a. 90-degree bend followed by a 180-degree bend
b. Two 45-degree bends
c. Three 90-degree bends
d. 180-degree bend followed by a 90-degree bend

Answer:

An acceptable combination of conduit bends between pull points according to the NEC is option b: Two 45-degree bends.

Have you ever wondered about the best way to navigate conduit bends when pulling wires for electrical installations? The National Electrical Code (NEC) provides guidelines to ensure safe and efficient wire installation practices.

The correct answer to the question of which combination of conduit bends between pull points is acceptable is option b: Two 45-degree bends. The NEC generally limits the total sum of angles between pull points to a maximum of 360 degrees.

Therefore, options with bends totaling more than 360 degrees, such as a 90-degree bend followed by a 180-degree bend and three 90-degree bends, are not acceptable. While a 180-degree bend followed by a 90-degree bend does not exceed the limit, it is impractical and could make pulling wires very difficult due to the sharp angles.

Two 45-degree bends, totaling 90 degrees, is not only permissible but also practical for wire installation. This combination allows for smooth wire pulling without exceeding the maximum angle limitations set by the NEC.
