Which terminals must be connected to the equipment grounding terminal of a panelboard in a wet-niche luminaire supply circuit?

• A. Hot conductor terminals
• B. Neutral conductor terminals
• C. Equipment grounding conductor terminals
• D. Bonding conductor terminals

Answer: (C)

In a wet-niche luminaire supply circuit, it is essential to connect the equipment grounding conductor terminals to the equipment grounding terminal of the panelboard. This connection ensures that any fault current has a safe path to ground, reducing the risk of electrical shock and equipment damage. The equipment grounding terminal plays a vital role in maintaining safety by creating a grounding system that can displace dangerous voltages and prevent hazardous situations, particularly in wet or damp environments where moisture can enhance conductivity. This is critical in the context of wet-niche luminaires, which are specifically designed for installation in areas exposed to water. Thus, ensuring the equipment grounding conductors are properly connected is vital for complying with safety standards and protecting both users and the electrical system.
