What is necessary for luminaires located in areas susceptible to water?

For luminaires installed in areas that are susceptible to water, it is essential that they are listed for damp or wet locations. This requirement is in accordance with safety standards set forth in the National Electrical Code (NEC). Luminaires that are specially rated for these conditions are designed to withstand moisture and prevent the potential hazards of electrical shock or short circuits that can occur in wet environments.

The listing signifies that the luminaire has been tested and meets the necessary performance criteria to ensure safety and functionality in such conditions. This includes considerations for materials, sealing, and overall construction, which help to protect the electrical components from water ingress.

In contrast, simply relying on a ground fault circuit interrupter does not sufficiently address the need for the luminaires themselves to be designed for exposure to moisture. Similarly, stating that only the bulbs need waterproof features overlooks the necessity for the entire luminaire to be appropriately rated. Lastly, installing the luminaires without any specific requirements would not ensure adequate safety and compliance with the NEC, which mandates specific standards for installations in wet or damp locations.
