What must be performed on luminaires installed in commercial kitchens according to Article 410?

Regular maintenance and cleaning of luminaires installed in commercial kitchens is essential for ensuring safe operation. This practice is mandated because commercial kitchens often encounter high levels of grease, humidity, and food particles that can accumulate on light fixtures. Such buildup not only diminishes the luminaires' effectiveness but also poses a fire hazard if ignited.

By maintaining and cleaning the fixtures, the risk of failure is reduced, the lifespan of light sources is extended, and optimal illumination levels can be maintained, which is crucial for food preparation and safety. This aligns with the NEC's emphasis on ensuring that electrical installations are safe, functional, and effective in their specific environments, particularly in high-demand settings like commercial kitchens. Regular maintenance and cleaning thus not only enhance safety but also contribute to the efficiency and reliability of the lighting systems in these settings.
