What must be ensured when installing a luminaire in a wet location?

When installing a luminaire in a wet location, it is essential that the luminaire is specifically rated for such environments. Wet location-rated luminaires are designed to withstand moisture and water exposure, ensuring that electrical components are protected and safe to use in these conditions. This rating typically includes features like sealed lenses, gaskets, and corrosion-resistant materials, which help prevent water intrusion and mitigate the risk of electrical shock or short-circuiting.

Choosing a luminaire that is not rated for wet locations could lead to safety hazards and reduce the lifespan of the light fixture due to corrosion or damage from moisture. Therefore, ensuring that the luminaire is properly rated is the fundamental requirement for installations in wet areas.

In contrast, while being under a roof or having all components above ground level may provide additional protection, they do not replace the necessity for the luminaire itself to be rated for wet locations. Similarly, the specific type of light bulb or component elevation does not address the key concern of moisture protection provided by the luminaire's design and certification.
