When installing electrical equipment in wet locations, what must be ensured?

When installing electrical equipment in wet locations, it is essential to use equipment that is rated specifically for wet location use. This rating indicates that the equipment has been tested and certified to withstand exposure to moisture, rain, and environmental conditions typical of wet areas. It ensures that the materials and design of the equipment can resist corrosion and are sealed adequately to prevent water ingress, thus maintaining safety and functionality over time.

Using equipment that is rated for wet locations helps to prevent potential hazards such as electrical shock or fire, which can arise from moisture affecting unprotected electrical components. While painting equipment may provide some level of protection, it does not substitute the necessity for proper ratings. Additionally, not all outdoor-rated fixtures are suitable for all wet environments, and waterproof connections, while important, are just one aspect of overall wet location compliance. Therefore, ensuring that all equipment is rated for wet location use is critical for safe and effective installation.
