What type of luminaires can be located less than 5 ft from pool walls?

Low-voltage gas-fired luminaires are explicitly allowed to be installed within 5 feet of pool walls in accordance with the NEC guidelines. The rationale behind this is that low-voltage systems are designed to operate at a safer voltage level, reducing the risk of electrical shock in wet environments such as pools. By using low-voltage luminaires, the chances of a hazardous situation occurring due to water contact are minimized, making them suitable for installation in close proximity to pool areas.

In contrast, options such as high-voltage luminaires, standard incandescent lights, and other conventional light sources do not have the same safety margin when it comes to installation near water bodies. High-voltage luminaires could potentially present increased electrical shock hazards, especially in environments where water is involved. Therefore, they must adhere to stricter distance requirements from the pool walls. Understanding these safety measures is crucial when working with electrical installations in areas exposed to water.
