- NEMA DESIGNATIONS
The National Electrical Manufacturer’s Association (NEMA) has developed a set of standards for the Electrical Industry to assist the user and the manufacturer in the identification and the standardization of many electrical components.
- NEMA Type 1- General Purpose indoor. Type 1 enclosures are intended for use INDOORS, primarily to prevent accidental contact of personnel with the enclosed equipment, in areas where unusual service conditions do not exist.
- NEMA Type 12- Dust tight, drip tight. Type 12 enclosures are intended for use INDOORS to protect the enclosed equipment against falling non-corrosive liquids and falling dirt.
- NEMA Type 3-Dustight, Raintight and Sleet/Ice Resistant Outdoor. Type 3 enclosures are intended for use OUTDOORS to protect the enclosed equipment against windblown dust and water.
- NEMA Type 3R- Raintight and Sleet/Ice Resistant Outdoor. Type 3R enclosures are intended for use OUTDOORS to protect the enclosed equipment against rain and meet the requirements of Underwriters’ Labs UL508 applying to “Rainproof Enclosures”.
- NEMA Type 4- Watertight and Dusttight Indoor and Outdoor. Type 4 enclosures are intended for use INDOORS or OUTDOORS to protect the enclosed equipment against splashing water, seepage of water, falling or hose directed water, and severe external condensation.
- NEMA 4X- Watertight, Dust tight and Corrosion Resistant Indoor and Outdoor. Type 4X enclosures have the same protection and provisions as Type 4 enclosures, and in addition, are corrosion- resistant.
