Which code section mandates the use of listed luminaires?

The requirement for the use of listed luminaires is found in Section 410.4 of the National Electrical Code. This section establishes the importance of using luminaires that have been tested and found to meet specific safety standards. Listed luminaires ensure compliance with safety regulations and performance criteria, reducing risks associated with electrical failures, overheating, or fire hazards.

By specifying that only listed luminaires be utilized, the NEC aims to promote safer installation practices and ensure that lighting fixtures have been rigorously evaluated for their intended use. This regulation is crucial for maintaining safety in residential, commercial, and industrial installations, as it ensures that all lighting products meet established safety and performance standards. Sections 410.2 and 410.3 cover definitions and general requirements regarding luminaires but do not specifically mandate the use of listed products. Section 410.5 discusses mounting requirements for fixtures or luminaires, rather than the listing requirement itself.
