Which option describes the purpose of bonding the neutral to the equipment grounding conductor?

• A. To connect the hot and neutral to close the circuit
• B. To connect the ground rods to the service
• C. To bond the neutral to the equipment grounding conductor
• D. To separate the neutral from the grounding system

Answer: (C)

Bonding the neutral to the equipment grounding conductor at the service equipment creates a defined reference to earth and a low-impedance path for fault currents to return to the source. This ensures any fault that makes a metal part live induces a strong enough current to trip the overcurrent device, clearing the fault quickly and keeping exposed parts at or near earth potential for safety. It’s not about completing the normal hot-to-neutral circuit, nor is it simply about connecting ground rods, and in subsystems the neutral and grounding conductors are separated. The bonded connection at the service provides the required fault-clearing path and stable reference.
