How many feet above the water level must lighting fixtures be installed to avoid requiring ground fault circuit interrupters?

Lighting fixtures must be installed at least 5 feet above the water level to avoid requiring ground fault circuit interrupters (GFCIs). This regulation is in place to enhance safety in environments where water and electricity intermingle, particularly in commercial pool settings.

By maintaining a height of at least 5 feet, the fixtures are less likely to be exposed to splashes or water accumulation, which could increase the risk of electrical shock. This elevation acts as a buffer zone, providing a greater safety margin and ensuring that the fixtures are positioned away from potential water contact, thus reducing electrical hazards.

Choosing a height other than 5 feet may not provide sufficient safety, as the likelihood of water exposure increases. Therefore, the 5-foot height is the minimum requirement stipulated in safety regulations to safeguard both patrons and staff using the space.
