What are the minimum distance requirements for luminaires from combustible materials?
Regulation 422.3.1 states:
"Except for equipment for which an appropriate product standard specifies requirements, a luminaire shall be kept at an adequate distance from combustible materials. Unless otherwise recommended by the manufacturer, a small spotlight or projector shall be installed at the following minimum distance from combustible materials:
(i) Rating up to 100 W - 0.5 m
(ii) Over 100 and up to 300 W - 0.8 m
(iii) Over 300 and up to 500 W - 1.0 m."
This regulation emphasizes the importance of maintaining safe distances between luminaires and combustible materials to prevent fire hazards. The specified distances vary based on the power rating of the luminaire, ensuring that higher wattage luminaires are kept further away from combustible materials to mitigate risk. Always follow the manufacturer's recommendations if they specify different requirements.
