How far must the disconnecting means for all ungrounded conductors be located from the inside walls of a pool?

The requirement for the disconnecting means for all ungrounded conductors around a pool is set to ensure electrical safety and prevent accidental shocks or electrocution. The National Electrical Code (NEC) specifies that the disconnecting means must be located at least 5 feet away from the inside walls of a pool. This distance is established to minimize risks associated with water proximity, which can increase the likelihood of electrical hazards.

By having the disconnection point positioned at this distance, it creates a safer environment for anyone using the pool. It ensures that individuals in or near the water are less likely to come into contact with electrically energized parts of the system while also facilitating safe access for service workers to turn off the power if necessary. This distance is also important to avoid the effects of splashing water or pool maintenance activities that could bring a person close to the electrical system.
