NEMA Enclosure Rating

Not Rated this refers to electrical enclosures that have not been tested for protection against dust and water.
1 is a safety rating for indoor electrical enclosures with nongasketed doors that specifies a degree of protection against incidental contact and the entry of solid objects such as falling dirt.
2 is a safety rating for indoor electrical enclosures with nongasketed doors that specifies a degree of protection against incidental contact and the entry of solid objects (falling dirt) or water (dripping, light-splashing).
3 is a safety rating for indoor and outdoor electrical enclosures that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (snow, rain), and against exterior ice formation.
3S is a safety rating for indoor and outdoor electrical enclosures that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (rain, sleet, snow). They also help ice-laden external mechanisms remain operable.
3R is a safety rating for indoor and outdoor electrical enclosures–often called rain-tight or rain-proof–that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (rain, snow), and against exterior ice formation.
4 is a safety rating for indoor and outdoor electrical enclosures with gasketed doors that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (snow, rain, water splashes and sprays), against occasional washdowns, and against exterior ice formation.
4X is a safety rating for indoor and outdoor electrical enclosures – also known as washdown enclosures – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (rain, snow, water splashes and sprays), against corrosion, and against exterior ice formation.
5 is a safety rating for indoor electrical enclosures that specifies a degree of protection against incidental contact and the entry of solid objects (falling dirt, settling dust/lint) or water (dripping, light splashing).
6 is a safety rating for indoor and outdoor electrical enclosures – also known as submersible enclosures – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt) or water (sprays and occasional submersion at a limited depth), and against exterior ice formation.
6P is a safety rating for indoor and outdoor electrical enclosures – also known as submersible enclosures – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt) or water (sprays and prolonged submersion at a limited depth), and exterior ice formation.
8 is a safety rating for indoor and outdoor electrical enclosures used in hazardous locations classified as Class I, Division 1, Groups A, B, C, and D according to NFPA 70. They provide protection against internal explosions and prevent the ignition of flammable gases or vapors due to sparks, arcs, or heat.
12 is a safety rating for indoor electrical enclosures that specifies a degree of protection against incidental contact and the entry of solid objects (falling dirt, circulating dust/lint) or water (dripping, light splashing).
13 is a safety rating for indoor electrical enclosures – often called oil-proof or oil-tight – that specifies a degree of protection against incidental contact and against the entry of solid objects (falling dirt, circulating dust), water (drips, light splashes), and oil or noncorrosive coolants (sprays, splashes, seepage).
