NEMA designations are normally applied to describe the extent of performance expectations. You will find many, however here are the common types of NEMA electrical enclosure:

NEMA Enclosures

NEMA Enclosures

NEMA 1 Electrical Enclosure: Provide the least protection and are mostly used indoors.
NEMA 2 Electrical Enclosures: The enclosures offer extra protection layer against light water drops.
NEMA 3 Electrical Enclosure: Can be mounted both outdoors and indoors. You will notice them installed outdoors more often since they provide extra protection against rain, falling dirt, sleet, snow and external ice development.
NEMA 4 Electrical Enclosure: Exhibit watertight features and offer greater degree of protection against extreme weather conditions.
NEMA 4X Electrical Enclosure: Offer similar protection as NEMA 4 Enclosures though with extra protection against corrosion.
NEMA 6 Electrical Enclosure: made for both outdoor and indoor use. It commonly finds use in applications where there may be occasional momentary immersion in water.
NEMA 6P Enclosure: Gives similar protection level as NEMA 6 enclosures, though allows for extended immersion in water. It adds an extra protection layer against corrosion as well.
NEMA 7 Electrical Enclosure: designed for indoor hazardous environments as specified in NFPA 70.
NEMA 12 Electrical Enclosure: Irrespective of their higher rating, the enclosure ranks higher than NEMA 1 and 2. However, it offers less protection compared to outdoor enclosures such as NEMA 4X and 6P.
