Metal poles that support lighting fixtures are required to be bonded to the equipment grounding conductor to ensure safety and provide a pathway for fault currents. This bonding is crucial because it helps prevent electrical shock hazards and reduces the risk of fire. By connecting the metal poles to the equipment grounding conductor, any stray electrical currents can be safely redirected to the ground. This connection is part of the overall grounding system in electrical installations, which serves to stabilize voltage levels and protect both equipment and personnel from electrical faults.

The equipment grounding conductor is specifically designed for this purpose, as it is meant to carry fault currents only under fault conditions and to provide a low-resistance path back to the ground. While other components, like neutral or phase conductors, serve different roles in the electrical system, they do not provide the necessary safety bonding required for metal structures that may become energized. Proper bonding to the equipment grounding conductor is a critical aspect of electrical safety in installations involving metal poles.
