According to specification, what should luminaires and equipment be mechanically connected to?

• A. Ground Fault Circuit Interrupter
• B. Equipment grounding conductor
• C. Service entrance conductors
• D. Neutral conductors

Answer: (B)

Luminaires and equipment must be mechanically connected to the equipment grounding conductor to ensure safety and proper function. This connection serves primarily as a safety measure to prevent electrical shock hazards. The equipment grounding conductor provides a low-resistance path back to the ground to facilitate the operation of protective devices, such as circuit breakers or fuses, in case of a fault condition. When a fault occurs, such as a short circuit or equipment malfunction, the current can take an unintended path. By being connected to the equipment grounding conductor, any stray current can flow safely to the ground, triggering protective devices to disconnect the circuit, thereby minimizing the risk of electric shock and fire hazards. It's important to recognize that grounding is a critical element in electrical systems, particularly for metal parts of equipment that could become energized. This mechanical connection ensures that all exposed metal surfaces are at the same electrical potential as the ground, enhancing safety for users and protecting the equipment itself.
