Question 1

What is a wire nut (twist-on connector) primarily used for?

Accepted Answer

Joining two or more stripped electrical conductors together

Answer

A wire nut's internally threaded plastic cap twists onto stripped wire ends, creating an insulated, secure connection between two or more conductors.

Question 2

A socket wrench extension bar is most useful for:

Accepted Answer

Reaching and turning fasteners in deep or obstructed locations

Answer

An extension bar increases the distance between the ratchet handle and the socket, allowing the technician to reach fasteners recessed deep in equipment.

Question 3

What physical principle does a non-contact voltage tester use to detect live AC wires?

Accepted Answer

Capacitive coupling to the AC electric field

Answer

Non-contact testers sense the alternating electric field surrounding a live AC conductor through capacitive coupling, triggering a visual or audible alert.

Question 4

Which screwdriver type is required for a Phillips head screw?

Accepted Answer

Phillips (cross-point)

Answer

A Phillips screw has a cross-shaped recess designed to engage the matching cross-point tip of a Phillips screwdriver for driving and removal.

Question 5

In electrical wiring, what does the AWG designation indicate?

Accepted Answer

American Wire Gauge

Answer

AWG (American Wire Gauge) is the U.S. standard for expressing wire conductor diameter; a lower AWG number means a larger diameter and higher current capacity.
