Preview Questions Electrician | Role Specific Skill

Question 1: How can an Electrician ensure that a newly designed circuit complies with local electrical codes?

Which action should you take?

Choose only one option

Review and apply all relevant national and local electrical codes (e.g., NEC), and perform load calculations to ensure the design meets regulatory standards

Rely on manufacturer specifications without consulting the code

Use outdated versions of the code and assume compliance

Focus only on aesthetics and ignore code requirements

Question 2: When installing a new electrical panel, what is the most important step to ensure the system is properly grounded?

Which action should you take?

Choose only one option

By connecting the panel directly to a power source without grounding

By relying on the metal conduit as the ground path

By connecting the panel to a neutral bus bar

By using a dedicated ground bus bar and ensuring the panel is connected to a grounding electrode

Question 3: When designing a dedicated circuit for an electric oven in a residential setting, how do you determine the correct breaker size?

Which action should you take?

Choose only one option

By sizing the breaker based on the maximum load current without adjustment

By using the standard 15-amp circuit size

By considering the oven's rated wattage and applying the NEC's demand factors

By using the smallest breaker available for safety

Question 4: When designing a lighting circuit for a commercial space, how do you ensure the proper number of circuits are used?

Which action should you take?

Choose only one option

By calculating the wattage of the lights and ensuring the total load does not exceed the circuit's capacity

By using one circuit for all lighting and assuming the load will be balanced

By using as few circuits as possible to reduce installation costs

By distributing lighting evenly across multiple phases without load calculations

Question 5: What tool is most commonly used to check for a live wire during electrical installation?

Which action should you take?

Choose only one option

A voltage tester or multimeter

A hammer

A pipe wrench

A circuit breaker

Question 6: What is the correct procedure for designing a dedicated circuit for an air conditioning unit in a commercial building?

Which action should you take?

Choose only one option

Use an undersized breaker to minimize cost

Design a dedicated circuit with the correct wire size, breaker size, and grounding, ensuring the system can handle the air conditioner's electrical demands without overloading

Install a shared circuit with other equipment

Use a standard residential circuit without considering load
