What must be true about luminaires installed in a fountain?

The requirement for luminaires installed in a fountain to be removable from the water for maintenance is essential for several reasons. First, maintenance tasks may include cleaning, bulb replacement, or inspections, which necessitate access to the fixtures without draining the fountain or disrupting its operation. When luminaires can be removed easily, it enhances safety for maintenance personnel and ensures that the fixtures can be kept in good working order without excessive labor or risk.

This option aligns with the NEC's emphasis on safety and accessibility in installation methods for electric components in aquatic environments, where the combination of water and electricity can be particularly hazardous. By allowing luminaires to be removable, the code supports a practical approach to ensuring the longevity and safety of both the lighting systems and the users of the fountain.
