What is the difference between a grounding conductor and a bonding conductor?

The distinction between a grounding conductor and a bonding conductor lies in their specific functions within an electrical system. A grounding conductor is designed to provide a direct path to the earth for fault currents, which helps to protect both equipment and individuals from electrical shock. This safety feature is crucial during fault conditions, as it allows excess current to safely dissipate into the ground, reducing the risk of fire or equipment damage.

On the other hand, a bonding conductor serves to connect various metal components within an electrical system, ensuring that they are at the same electrical potential. This is particularly important in preventing shock hazards, as it mitigates the risk of voltage differences that could arise between conductive surfaces. By bonding these components together, the circuit is made safer and more reliable.

Thus, the correct response highlights this critical difference: while the grounding conductor focuses on providing a safe discharge path for fault current, the bonding conductor is concerned with maintaining uniform potential among metal parts, which helps ensure system safety and integrity.
