CAT Tools & Equipment Operation 3

Question 1

When terminating alarm wiring at a screw terminal, the wire end should be:

Accepted Answer

Twisted into a clockwise hook matching the screw's tightening direction

Answer

Forming a clockwise hook ensures the wire wraps tighter as the screw is tightened, creating a secure connection.

Question 2

A conduit bender is marked with degree indicators. When making a 90-degree stub-up in rigid conduit, the technician should:

Accepted Answer

Align the arrow mark with the measured start point and apply steady foot pressure

Answer

Aligning the bender's arrow with the stub measurement mark and applying steady pressure produces an accurate 90-degree bend.

Question 3

What safety precaution is essential when using a powder-actuated fastening tool on an alarm installation job site?

Accepted Answer

Obtain proper training/certification and ensure bystanders are clear of the muzzle direction

Answer

Powder-actuated tools require operator certification and a clear safety zone because the fastener can penetrate or ricochet with lethal force.

Question 4

Which type of terminal tool is used to crimp an insulation displacement connector (IDC) onto a twisted pair wire without stripping the insulation?

Accepted Answer

110-type punch-down tool

Answer

A 110-type punch-down tool seats the conductor into an IDC block terminal and cuts the excess wire in one motion.

Question 5

A technician notices the drill motor is overheating during a long masonry drilling job. The correct action is to:

Accepted Answer

Answer

Allowing the drill motor to cool prevents thermal damage to the windings and prolongs tool life.
