Preview Questions Electrician | Role Specific Skill

Question 1: How should an Electrician ensure that circuits are adequately spaced and routed to minimize interference in a commercial building?

Which action should you take?

Choose only one option

Install multiple circuits in the same conduit without considering interference

Use separate conduits and adequate spacing between circuits, particularly for high-voltage and low-voltage systems, to minimize interference and signal degradation

Install all circuits in the same conduit to save space

Ignore spacing and install circuits arbitrarily

Question 2: If a breaker is tripping repeatedly, what is the most likely cause?

Which action should you take?

Choose only one option

The circuit is underutilized and the breaker is unnecessary

The breaker is faulty and needs to be replaced

The wiring insulation is too thick

There is an overload or short circuit in the circuit

Question 3: What is the purpose of a ground wire in an electrical system?

Which action should you take?

Choose only one option

To increase the overall power of the circuit

To provide a safe path for stray electrical currents to return to the earth and reduce the risk of electric shock

To reduce the cost of the system installation

To ensure the electrical system operates without any interruptions

Question 4: When troubleshooting an electrical system, what should you use to safely measure current in a live circuit?

Which action should you take?

Choose only one option

Continuity tester

Clamp meter

Insulation resistance tester

Voltage tester

Question 5: What is the correct method for grounding electrical systems in a commercial building?

Which action should you take?

Choose only one option

Use a dedicated ground conductor, connect all metallic parts to the ground, and follow local electrical codes for grounding electrodes

Disregard grounding if the system is insulated

Use the neutral conductor for grounding

Use any available metal surface for grounding

Question 6: When installing a 240-volt circuit, what type of breaker is required according to the NEC?

Which action should you take?

Choose only one option

Double-pole breaker

Single-pole breaker

Triple-pole breaker

Four-pole breaker
