The recommended clearance for a service drop near a swimming pool is indeed established for safety reasons, ensuring that there is sufficient space between the overhead electrical lines and the water to prevent any risk of electrocution or electrical hazards. The specification of 22-1/2 feet vertically and 10 feet horizontally is based on national safety standards which take into account the potential for splashing water and the presence of individuals who may be at risk of contact with overhead electrical lines.
This vertical clearance of 22-1/2 feet helps ensure that, in the event of a high water level or accidental splashing, the electrical lines remain safely out of reach. The horizontal clearance of 10 feet ensures that any person near the edge of the pool will not be at risk of coming into contact with the service drop, especially in the event of activities like diving or jumping into the water. This approach illustrates the importance of maintaining safe distances for overhead electrical installations near recreational facilities like swimming pools.
Observing these clearances is crucial for ensuring both compliance with safety regulations and the protection of individuals enjoying the pool area.
