  • The National Electrical Manufacturers Association (NEMA) has created standards for electrical equipment since 1926.

    NEMA's approximately 450 members are involved in the development of codes, standards and conformity assessment policy across the globe. It provides support to 49 product group technical committees and 20 ANSI-accredited standards committees and promotes adoption of NEMA standards.

    A NEMA standard defines a product, process or procedure with reference to one or more of the following: nomenclature, composition, construction, dimensions, tolerances, safety, operating characteristics, performance, rating, testing and the service for which the product(s) are designed.

    NEMA has published thousands of standards, application guides and technical papers.
