CEA Conduit Bending and Installation 5

Question 1

What is the correct procedure for deburring the inside of a cut conduit end before pulling wire?

Accepted Answer

Use a conduit reamer or deburring tool to remove sharp edges

Answer

A conduit reamer or deburring tool removes sharp internal edges that could cut wire insulation during pulling.

Question 2

The 'developed length' of a conduit bend refers to:

Accepted Answer

The arc length of the conduit through the bend

Answer

Developed length is the actual length of conduit consumed as it travels through the arc of the bend.

Question 3

When concentric bends are required (multiple conduits bending around the same radius), what is adjusted for each successive conduit?

Accepted Answer

The developed length of each successive conduit

Answer

Each successive conduit in a concentric set must have a longer developed length to maintain the same bend radius on a larger arc.

Question 4

In which situation is a conduit body (LB, LR, LL, T) preferred over a box with a cover?

Accepted Answer

When making a direction change in a short run with limited pulling access

Answer

Conduit bodies allow direction changes in tight spaces and can be used as pull points, though splices are generally not permitted inside them.

Question 5

Flexible Metal Conduit (FMC) is typically used in final connections to:

Accepted Answer

Motors and equipment subject to vibration or requiring movement

Answer

FMC's flexibility makes it ideal for final connections to motors or equipment that vibrates, moves, or requires periodic repositioning.
