NEC 2002 100 Definitions
Location, Damp. Locations protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture. Examples of such locations include partially protected locations under canopies, marquees, roofed open porches, and like locations, and interior locations subject to moderate degrees of moisture, such as some basements, some barns, and some cold-storage warehouses.
From UL White Book
Enclosure Type Number Provides a Degree of Protection Against the Following Environmental Conditions*
1 Indoor use
2 Indoor use, limited amounts of falling water
3R Outdoor use, undamaged by the formation of ice on the enclosure**
3 Same as 3R plus windblown dust
3S Same as 3R plus windblown dust; external mechanisms remain operable while ice laden
4 Outdoor use, splashing water, windblown dust, hose-directed water, undamaged by the formation of ice on the enclosure**
4X Same as 4 plus resists corrosion
5 Indoor use to provide a degree of protection against settling airborne dust, falling dirt, and dripping noncorrosive liquids.
You will have to decide which enclosure type would be acceptable for your condition.
I hope this helps!
