Sample interview questions: Can you explain the process you follow for testing and inspecting electrical systems in residential buildings?

Sample answer:

1. Visual Inspection: Begin by thoroughly inspecting all electrical components, including wiring, outlets, switches, panels, and fixtures. Look for signs of damage, loose connections, or corrosion.

2. Voltage Testing: Use a voltmeter to test the voltage at various points in the system, ensuring it meets code requirements and is consistent throughout.

3. Insulation Resistance Testing: Measure the insulation resistance between conductors and ground using a megohmmeter. High readings indicate good insulation, while low readings may indicate potential safety hazards.

4. Ground Fault Circuit Interrupter (GFCI) Testing: Test all GFCIs by pressing the “test” button to ensure they are functioning correctly and are providing proper protection.

5. Outlet Testing: Utilize an outlet tester to verify that outlets are properly wired and providing the correct polarity and voltage.
