Conduit Bending: Optimizing Conduit Runs for…

Q: What is the primary purpose of bending conduit?

To change the direction of the conduit run. — Bends allow conduit to navigate obstacles and change direction.

Q: What is the most common angle for a standard bend (90-degree bend)?

90 degrees — A 90-degree bend changes the conduit's direction completely.

Q: What tool is typically used to bend conduit?

A conduit bender (hickey). — A conduit bender provides the leverage needed to bend the conduit.

Q: What does 'take-up' refer to in conduit bending?

The amount of conduit consumed by the bend. — Take-up is the distance shortening due to the bending process.

Q: What does 'gain' refer to in conduit bending?

The distance between the back of the first bend to the back of the second bend (for 3-bend saddles). — Gain is the difference in distance due to the bends in a saddle.

Q: Why is it important to minimize the number of bends in a conduit run?

To increase wire pulling ease and reduce friction. — Fewer bends mean easier wire pulling and lower resistance.

Q: What is the maximum number of bends allowed between pull points according to the National Electrical Code (NEC)?

360 degrees total — NEC dictates a maximum of 360 degrees of bends between pull points.

Q: Which of the following bends is used to change direction and clear an obstruction?

Offset bend — An offset bend moves the conduit laterally to go around an obstacle.

Q: What is the primary function of a saddle bend?

To offset the conduit over an obstacle. — Saddle bends are specifically for clearing obstacles.

Q: When measuring for a 90-degree bend, where should you measure from?

From the end of the conduit to the center of the bend. — Measuring from the end to the center of bend ensures correct stub up length.
