What is the required clearance above swimming pools for overhead service drops?

The required clearance above swimming pools for overhead service drops is 22 feet, 6 inches. This clearance is established to ensure safety and to minimize the risk of electrical hazards. When overhead power lines are installed above areas where people may be present, such as swimming pools, the distances are set to prevent accidental contact or electrocution, particularly when considering the potential for reaching up into those areas during activities like diving or using tall pool accessories.

In the case of swimming pools, the National Electrical Code (NEC) specifies this height requirement to ensure that overhead service conductors are sufficiently elevated above the water surface. The significant height helps protect individuals in and around the pool, accommodating for any movements or activities that may occur. Lower clearances, like 10 feet, 18 feet, and 3 feet, would not provide adequate protection, as they could increase the risk of accidental contact with the power lines, especially when taking into account the height of individuals, ladders, or pool equipment.
