How does Article 410 categorize recessed luminaires?

Article 410 of the National Electrical Code categorizes recessed luminaires under specific guidelines concerning fire safety and thermal protection. This is important because recessed luminaires are often installed within ceilings or walls, where they can create potential fire hazards if not properly designed and installed. The guidelines encompass the construction, materials, and installation practices needed to ensure that these fixtures do not present a risk of fire due to overheating or inadequate ventilation.

This categorization takes into account the various components of recessed luminaires, such as the type of housing, the type of light source used, and how the installation interacts with building materials. The code sets forth requirements for installing insulation around these fixtures, providing thermal protection, and ensuring that any fire-rated ceilings are not compromised by the installation of recessed lights.

Unlike the options that offer vague classifications, such as designating them as portable or decorative without guidelines, Article 410 specifically addresses the safety and operational standards necessary for recessed luminaires to mitigate fire risks and ensure proper thermal management.
