For what voltage is the lighting system for pool, spa, and fountain limited in a nonmetallic raceway?

The correct voltage limit for a lighting system for pools, spas, and fountains running in a nonmetallic raceway is 30 volts. This limitation is established to enhance safety, reducing the risk of electric shock in water environments, where the presence of water increases the potential for electrical hazards. By restricting the voltage to 30 volts, the risk to individuals who may come into contact with water in these areas is significantly minimized.

Higher voltages would increase safety risks, making it crucial that installations in such sensitive environments adhere strictly to this limit. This standard reflects a careful consideration of the unique hazards associated with water and electricity, ensuring a safer experience for users of pools, spas, and fountains.
