CEA Conduit Bending and Installation 3

Question 1

What is the term for a conduit bend that rises from a horizontal run to connect to a box mounted on a wall?

Accepted Answer

Kick

Answer

A kick is a single bend that angles a conduit run to meet a box or enclosure offset from the original run direction.

Question 2

When bending a three-bend saddle around a 2-inch obstruction, what are the three bend angles typically used?

Accepted Answer

22.5°, 45°, 22.5°

Answer

A three-bend saddle uses 22.5°, 45°, and 22.5° bends to clear an obstruction while keeping the conduit run parallel.

Question 3

The multiplier used to calculate the distance between bends when making a 30-degree offset is approximately:

Accepted Answer

2.000

Answer

A 30-degree offset uses a multiplier of 2.0; the distance between bends equals the offset height multiplied by 2.0.

Question 4

Rigid Metal Conduit (RMC) differs from Intermediate Metal Conduit (IMC) primarily in:

Accepted Answer

Wall thickness and weight

Answer

RMC has thicker walls than IMC, making it heavier but providing greater mechanical protection in harsh environments.

Question 5

What does the 'shrink' of a conduit offset refer to?

Accepted Answer

The reduction in overall run length caused by the offset

Answer

Shrink is the amount by which a conduit run is shortened along its axis when an offset is added; it must be added to the mark location to hit the target.
