|A dry-location luminaire must be installed in a location that is not normally subject to dampness but may be subjected to temporary dampness. Ventilation is often used to prevent an accumulation of moisture at the luminaire, but the proper amount of ventilation is critical in extracting the moisture from the area. A very common application of this concept would be a dry-location luminaire installed above a mirror or vanity in a bathroom. A luminaire installed in a shower, where it is in close proximity to steam and water splash must be a damp- or wet-location luminaire and marked “Suitable for Damp Locations” or “Suitable for Wet Locations.”|
|A damp location is a location, either exterior or interior, that is normally or periodically subject to condensation of moisture in, on or adjacent to the luminaire. Article 100 states these are locations often protected from weather and not subject to saturation with water or other liquids but may be subject to moderate degrees of moisture. These could include partially protected locations under canopies, marquees, roofed open porches and some basements, barns and cold-storage facilities, such as walk-in coolers, freezers and warehouses.|
|A wet location is one where the luminaire is subject to saturation with water or other liquids, such as in a vehicle washing area, or where the luminaire is mounted in an unprotected location and directly subjected to the weather. Underground installations and installations where concrete slabs or masonry are in direct contact with the earth are also considered to be wet locations.|
|CSA tests products for compliance to national and international standards, and issue certification marks for qualified products.
