What is the requirement for underground wiring within 5 ft horizontally from the inside wall of a pool?

The requirement for underground wiring within 5 feet horizontally from the inside wall of a pool is that it shall be permitted. In the context of the National Electrical Code (NEC), specifically Article 680, wiring systems around pools and similar locations are given careful specifications to ensure safety while allowing for practical installation.

This permissibility is contingent upon meeting certain conditions outlined in the NEC to work safely in proximity to water, primarily focusing on the type of conductors used and the installation practices that protect against moisture and electrical hazards. While nearby wiring must adhere to specific installation standards, the NEC acknowledges that with appropriate measures, underground wiring can safely coexist with the aquatic environment.

Subjects such as burial depth, insulation, and overall construction methods come into play for safety and compliance; however, the base rule allows for the presence of wiring within that specified distance, provided the requirements are followed.
