What type of connection is required for electric-discharge and LED luminaires supported independently of the outlet box?

For electric-discharge and LED luminaires that are supported independently of the outlet box, the requirement is to connect them through raceways. This method offers several benefits, including proper protection of the wiring and facilitating organized routing of electrical conductors. Raceways provide a structured pathway for the electrical circuit, ensuring compliance with safety standards and allowing for future adjustments or replacements without disrupting the delicate internal connections of the luminaires.

Using raceways also aids in minimizing the risk of mechanical damage to the conductors, which is particularly important for installations where luminaries are mounted in locations prone to physical impact or in outdoor environments where additional protection from the elements is needed. Overall, connecting through raceways aligns with the NEC guidelines for safeguarding the integrity and safety of the electrical system in these applications.
