What criteria must lighting fixtures in pool areas meet according to NEC Article 680?

Lighting fixtures in pool areas must meet specific safety standards due to the unique hazards posed by water. According to NEC Article 680, the requirement that fixtures be specifically listed for wet locations is crucial for ensuring safety and minimizing the risk of electric shock. Wet locations are defined as areas that are subject to saturation with water or where moisture can accumulate and remain. Lighting fixtures designed for these conditions must have proper sealing and insulation to protect against moisture intrusion.

Using fixtures that are specifically listed for wet locations ensures they have undergone rigorous testing and are deemed safe for installation in areas where they may frequently come into contact with water or high humidity. This certification assures compliance with electrical safety standards, which is paramount in environments like swimming pools, where users are often wet.

While outdoor fixtures might seem appropriate, they may not be designed to withstand the conditions present in pool areas. Similarly, while fixtures positioned above water level might avoid immediate contact with water, they still require specific construction and materials to be safe. LED certification does not automatically address the requirements for wet location suitability, as not all LED fixtures are designed to operate safely in such conditions. Thus, the requirement for wet location listing is the most critical criterion according to NEC Article 680.
