What is the minimum horizontal distance required between an underground service subfeed and a pool?

1. 3 feet

2. 4 feet

3. 5 feet

4. 6 feet

The correct answer is: 5 feet

The requirement for the horizontal distance between an underground service subfeed and a pool is focused on safety and the prevention of electrical hazards. A distance of 5 feet is established as the minimum to ensure that there is adequate separation to reduce the risk of electrical shock or other dangers that could arise from the proximity of electrical installations to water features like pools. This standard takes into account the potential for water-related incidents and aims to prevent accidental contact between electrical components and water, which can conduct electricity. By maintaining a 5-foot distance, it allows for a buffer zone that enhances safety for individuals using the pool and minimizes the risk of electrical faults that may lead to severe injuries or damages. In contrast, options that suggest a shorter distance do not provide the recommended safety margin necessary to protect individuals. Therefore, 5 feet is the best minimum distance advised for separating an underground service subfeed from a swimming pool.
