Preview Questions Electrician | Role Specific Skill

Question 1: How can an Electrician diagnose a ground fault in an electrical system?

Which action should you take?

Choose only one option

Check for a loose connection and tighten it

Use an insulation resistance tester to check for leakage current between the conductors and ground

Assume it is a wiring issue without testing

Only rely on visual inspection

Question 2: How do you diagnose a lighting circuit that has power but no light output?

Which action should you take?

Choose only one option

Increase the power to the circuit

Check the breaker size to ensure it's appropriate for the load

Check the light bulbs and ensure they are properly connected

Check the switch for proper functionality and verify that the circuit is properly grounded

Question 3: When troubleshooting an electrical circuit that is not working, what is the first step an Electrician should take?

Which action should you take?

Choose only one option

Disconnect all devices and reset the power

Check for visible signs of damage or burnt components

Immediately replace the circuit breaker

Assume the wiring is the issue and start replacing wires

Question 4: What is the best approach for an Electrician when working with high-voltage cables during installation?

Which action should you take?

Choose only one option

Use appropriate personal protective equipment (PPE), follow lockout/tagout (LOTO) procedures, and ensure proper insulation and separation of high-voltage cables

Skip protective measures and focus on speed

Disregard safety precautions and handle cables casually

Use bare hands to manipulate high-voltage cables

Question 5: How do you properly install a ceiling fan, ensuring that all electrical connections are safely made?

Which action should you take?

Choose only one option

By using appropriate electrical box supports, connecting the power supply, and grounding the fan correctly

By connecting the wires to the fan and mounting it without securing the box

By only securing the fan to the ceiling without connecting the wiring

By assuming the fan's motor is pre-wired and ready to install

Question 6: How can an Electrician ensure that circuits are properly labeled and identified in an electrical panel?

Which action should you take?

Choose only one option

Use generic labels for all circuits

Label each circuit with a detailed description of its function, ensuring clarity and compliance with electrical code requirements

Use only color codes without a detailed label

Leave circuits unlabeled for later identification
