In what type of location is thermal protection for fluorescent luminaires essential according to electrical regulations?

Thermal protection for fluorescent luminaires is essential in indoor locations primarily because these environments pose a higher risk for potential overheating and fire hazards due to the confined space, presence of flammable materials, and lack of adequate ventilation. Indoor fluorescent luminaires can be installed in areas that may accumulate heat, such as attics, utility rooms, or spaces with low ceilings, which increases the importance of having thermal protection to prevent overheating.

While outdoor and garage environments have their own considerations, such as exposure to environmental elements and vehicular hazards, the need for thermal protection is more critical indoors where heat accumulation can occur more easily. In kitchens and garages, although there may be specific regulations, the overarching requirement for indoor installations emphasizes the need for such protective measures to safeguard against fire risks associated with household wiring and appliances.
