Preview Questions Electrical Supervisor | Role Specific Skill

Question 1: In an electrical maintenance procedure, when should a thermal imaging camera be used?

Which action should you take?

Choose only one option

When testing insulation resistance

To measure voltage drops across cables

To identify hotspots in electrical panels

When troubleshooting circuit breakers

Question 2: In performing electrical maintenance on a distribution panel, which component should be inspected first?

Which action should you take?

Choose only one option

The fuses to ensure they are correctly rated for the load

The circuit breakers for proper functioning and wear

The grounding system to ensure there is no loose or broken connection

The bus bars for signs of overheating and corrosion

Question 3: What should an electrical supervisor do if a team member fails to use lockout/tagout (LOTO) procedures during an installation?

Which action should you take?

Choose only one option

Perform the task personally to ensure safety

Assign the task to another worker and overlook the issue

Allow the worker to continue but monitor them closely

Immediately stop the work and reinforce LOTO procedures

Question 4: When performing maintenance on a circuit that frequently trips, what is the best first step?

Which action should you take?

Choose only one option

Test the circuit breaker for proper calibration and functionality

Check the system's voltage supply for spikes or dips

Inspect the load and ensure it is not drawing more current than the circuit is rated for

Inspect the circuit's grounding system to ensure no faults are present

Question 5: When troubleshooting a PLC-based control system, what is the primary factor in determining whether the PLC is at fault?

Which action should you take?

Choose only one option

Replace the PLC with a known working unit to confirm if it is the cause of the issue

Inspect all input and output connections for continuity and correct wiring

Test the program logic to verify that the correct sequence is being executed

Check the diagnostic LEDs on the PLC to identify faults and compare them with the manual

Question 6: When diagnosing an issue with an unresponsive PLC, what should be checked first?

Which action should you take?

Choose only one option

Inspect the physical environment for electromagnetic interference affecting the PLC

Check the program loaded into the PLC for errors

Verify the power supply and ensure that the PLC is receiving the correct input voltage

Check the PLC's input/output (I/O) modules for correct wiring and operation
