NCCER Ch 7 Review

The field bending of PVC requires a

• hickey

• heating unit

• segmented bender

• one-shot bender

You can use a hickey to bend

• RMC

• EMT

• PVC

• HDPE

What is the key to accurate bending with a hand bender?

• Correct size and length of handle

• Constant foot pressure on the back piece as well as force on the handle

• Using only the correct brand of bender

• Correct inverting of the conduit bender

In a right triangle, the side directly opposite the 90° angle is called the

• right side

• hypotenuse

• altitude

• base

Prior to making a 90° bend, which two measurements must you know?

A back-to-back bend is

• a two-shot 90° bend

• two 90° bends made back-to-back on a single piece of conduit

• an offset with four bends back-to-back

• a segmented bend

To prevent the ends of the conduit from being uneven, what additional information must you use when making parallel offset bends?

• Center-to-center spacing and tangent of ½ the offset angle

• Length of conduit and size of conduit

• Stub-up distance and take-up distance

• Offset angle and length of conduit

When making a saddle bend, the center of the saddle will cause the conduit to shrink for every inch of saddle depth.

• ⅜

• 3/16

• ¾

• 3/32

When using a pipe cutter, start the cut by rotating the cutter

• blade ½ turn tighter

• with the grain

• so the blade cuts into the conduit

• against the grain

Which of the following is typically threaded using a ratchet threader?

• EMT

• RMC

• LENC

• FMC
