Question 1

What is the primary function of a megohmmeter (megger)?

Accepted Answer

Test the insulation resistance of cables and motor windings

Answer

A megohmmeter applies high voltage and measures resistance in megaohms, revealing degraded or compromised insulation before it causes equipment failure.

Question 2

Which device is used during electrical maintenance to prevent accidental re-energization of equipment?

Accepted Answer

Lockout/tagout (LOTO) device

Answer

Lockout/tagout devices physically lock energy controls in the off position and attach warning tags, preventing accidental energization while maintenance is performed.

Question 3

What does an oscilloscope primarily display?

Accepted Answer

The waveform of a voltage signal plotted against time

Answer

An oscilloscope plots voltage against time, allowing technicians to visualize signal shape, frequency, amplitude, and timing relationships.

Question 4

A fish tape (wire puller) is primarily used to:

Accepted Answer

Pull electrical wire through conduit or wall cavities

Answer

Fish tape is a long, flexible steel or fiberglass tape fed through conduit or wall cavities to pull electrical wire from one location to another.

Question 5

Which tool compresses a metal terminal or connector firmly onto a wire to create a secure connection?

Accepted Answer

Crimping tool

Answer

A crimping tool uses a shaped die to deform a connector around a wire, creating a gas-tight mechanical and electrical connection without solder.
