What is the bonding and grounding requirement for luminaires?

The requirement for luminaires to be properly bonded and grounded is essential for ensuring safety in electrical installations. Proper bonding and grounding serve to mitigate the risk of electrical shock and fire hazards by providing a safe path for fault currents to flow to the ground. This is especially important in luminaires, which can be installed in various locations—and in some cases, exposed to moisture or other environmental factors that may increase the risk of electrical faults.

Bonding ensures that all metallic parts of the luminaire are connected together and to the grounding system, preventing any potential difference in voltage between these parts, which could pose a shock hazard. Grounding provides a direct physical connection to the earth, ensuring that any fault current can safely dissipate.

The code mandates that all luminaires, regardless of their type or installation environment, must meet these bonding and grounding requirements to maintain a consistent standard of safety. Therefore, the correct answer highlights the crucial nature of these requirements in preventing electrical hazards associated with lighting fixtures.
