What is the minimum distance below water a wall-mounted luminaire can be mounted in a pool?

The minimum distance below water that a wall-mounted luminaire can be installed in a pool is 4 inches. This requirement is established in electrical code regulations to ensure safety and reduce the risk of electric shock. By maintaining this minimum distance, the luminaire is positioned above the water level, which helps mitigate the possibility of electricity causing harm to swimmers or anyone in contact with the pool.

In addition to safety, the requirement takes into account the potential splashing of water and the maintenance of the light fixtures, ensuring that they are not directly exposed to water where a risk of electrical faults might occur. Overall, these regulations are designed to protect individuals using the pool while allowing for appropriate lighting in aquatic environments. Understanding these safety standards is crucial for electricians when planning installations in and around swimming pools.
