According to article 680 of the national electric code, a flush deck junction box for systems of 15 volts or less must be placed how far from the inside wall of the pool?

In accordance with Article 680 of the National Electrical Code (NEC), the requirement for the placement of a flush deck junction box for systems of 15 volts or less specifies a minimum distance from the inside wall of the pool. The correct distance is 4 feet. This regulation is designed to ensure safety and reduce the risk of electrical shock or other hazards arising from the proximity of electrical equipment to pool water.

The specified distance serves to create a buffer zone that minimizes the likelihood of water splashes or pool users inadvertently coming into direct contact with electrical components, which can pose significant risks. By adhering to a 4-foot distance, pool contractors help maintain safety standards that protect both the users and the integrity of the electrical systems installed near aquatic environments.

This regulation reflects the NEC's commitment to ensuring safe swimming pool environments, particularly in reducing the potential for electrical hazards associated with moisture, which is prevalent in pool areas.
