How far must the pool light junction box be from the inside wall of the pool unless separated by a barrier?

The requirement that the pool light junction box must be located at least 4 feet from the inside wall of the pool is rooted in safety considerations to minimize the risk of electrical shock and ensure that all electrical equipment is installed at a safe distance from water. This distance accounts for potential splashing or overflow that may occur and provides a safety buffer to prevent electrical hazards.

Additionally, the code specifies that if a barrier is installed that separates the junction box from the pool area, this distance can be altered. The intent of the 4-foot requirement emphasizes proper placement of electrical fixtures and promotes safety in wet environments. Understanding this requirement is crucial for anyone involved in the installation of pool lighting systems and compliance with the National Electrical Code (NEC) regulations.
