Overhead conductors for communications above swimming pools must be located at least _____ above the maximum water level.

For overhead conductors used for communications above swimming pools, the requirement is that they must be located at least 10 feet above the maximum water level. This regulation is in place to ensure safety and prevent accidental contact with live wires, which could result in severe electrical hazards.

Maintaining a height of 10 feet above the maximum water level provides a buffer that safeguards both the electrical installation and the pool users, accounting for factors such as splashing water or movement near the pool area. This standard aligns with the NEC's overall focus on promoting safe electrical practices in locations that pose higher risks due to water activities.
