Sample interview questions: How do you ensure that electrical systems in industrial settings are properly grounded and protected against electrical faults?
Sample answer:
Establishing Proper Grounding:
- Install a comprehensive grounding system that includes a main grounding electrode and a network of grounding conductors.
- Ensure that all exposed metal enclosures and equipment are securely connected to the grounding system with reliable bonding conductors.
- Periodically test the grounding system to verify its integrity and measure ground resistance values.
Protection against Electrical Faults:
- Circuit Breakers and Fuses: Utilize current-limiting devices such as circuit breakers and fuses to interrupt electrical flow in the event of a fault.
- Ground Fault Circuit Interrupters (GFCIs): Install GFCIs to detect ground faults and quickly disconnect power.
- Surge Protectors: … Read full answer
