Question: What is the primary purpose of bonding all non-current-carrying metal parts of an electrical system?
Answer options:
- To provide a path for lightning to dissipate. ✅ To create a low-impedance path for fault current to facilitate breaker operation.
- To drain static electricity from equipment.
- To equalize the potential of the system's neutral conductor.
Correct answer: To create a low-impedance path for fault current to facilitate breaker operation.
Explanation: Bonding connects all metallic components to create a continuous, low-impedance path for fault current to return to the source. This ensures that enough current flows during a ground fault to trip the overcurrent device quickly.
