Preview Questions Electrician | Role Specific Skill

Question 1: How can an Electrician ensure that electrical systems are properly grounded during installation?

Which action should you take?

Choose only one option

Skip grounding and assume safety

Use dedicated grounding conductors and ensure all equipment and system components are properly bonded to the ground to reduce the risk of electrical shock

Use any available metal surfaces for grounding

Ground systems to non-conductive surfaces

Question 2: When designing subpanels in a residential setting, what is the required neutral-to-ground separation?

Which action should you take?

Choose only one option

The neutral should be bonded to the ground at every point

The neutral and ground should be bonded together

The neutral and ground should be isolated in subpanels

Neutral and ground should only be separated in a main panel

Question 3: If a three-phase motor is not starting, which test should you perform to identify the problem?

Which action should you take?

Choose only one option

Inspect the physical condition of the motor's bearings

Check the phase-to-phase voltage balance

Check the motor's winding resistance for a short circuit

Measure the motor's power consumption

Question 4: When troubleshooting an electric stove that is not heating properly, what is the first step in determining the cause?

Which action should you take?

Choose only one option

Check the stove's temperature sensor

Inspect the wiring for physical damage

Check if the element has continuity

Measure the current being drawn by the stove

Question 5: How should an Electrician account for ambient temperature when designing a circuit in an industrial environment?

Which action should you take?

Choose only one option

Use standard circuit design without any consideration for environmental factors

Use only the maximum allowable wire size without considering temperature

Ignore temperature as it has no effect on circuit performance

Adjust the wire size and circuit protection to account for the higher resistance caused by elevated ambient temperatures, as per code guidelines

Question 6: What is the most effective method for installing and routing wiring for high-voltage systems in industrial buildings?

Which action should you take?

Choose only one option

Ignore raceways and install wiring directly on surfaces

Use appropriate high-voltage cables, proper insulation, and raceways, ensuring that all wiring is routed according to safety and code regulations

Use standard low-voltage components

Use unprotected wiring for high-voltage systems
