NEMA Type	Definition
1	Indoor use. Protects against dust, light, and indirect splashing but is not dust-tight; primarily prevents contact with live parts; used indoors and under normal conditions.
2	Indoor use. Drip-tight. Similar to Type 1 but with addition of drip shields; used where condensation may be severe (as in cooling and laundry rooms).
3	Indoor or outdoor use. Weather-resistant. Protects against falling dirt and windblown dust, against weather hazards such as rain, sleet and snow, and is undamaged by the formation of ice. Used outdoors on ship docks, in construction work, and in tunnels and subways.
3R	Same as 3, but does not include protection against windblown dust.
3S	Same as 3, but also operable when laden with ice.
3X, 3RX, 3SX	X indicates additional corrosion protection; commonly used near salt water.
4 and 4X	Indoor or outdoor use. Watertight. Used outdoors on ship docks, in dairies, in wastewater treatment plants and breweries. X indicates additional corrosion resistance.
5	Indoor use. Dust-tight. Provided with gaskets or equivalent to exclude dust; used in steel mills and cement plants.
6 and 6P	Indoor or outdoor use. Submersible. Design depends on specified conditions of pressure and time; submersible in water or oil; used in quarries, mines, and manholes. 6 is temporarily submersible, 6P withstands occasional prolonged submersion. Neither are intended for continuous submersion.
12 and 12K	Indoor use. provides some protection against dust, falling dirt, and dripping non-corrosive liquids. Meets drip, dust, and rust resistance tests.
13	Indoor use. Primarily used to provide protection against dust, spraying of water and non-corrosive coolants. Meets oil exclusion and rust resistance design tests.
