About NEMA

The National Electrical Manufacturers Association (or NEMA) is a US-based association created on September 1, 1926, when the Associated Manufacturers of Electrical Supplies and the Electric Power Club merged.

It is headquartered in Rosslyn, Virginia. It sets many common standards used in electrical products, among its 400+ members. NEMA has established a range of standards for electrical equipment enclosures. NEMA defines standards for many commonplace electrical interconnects, and outlines manufacturing standards for electrical products such as various grades of electrical enclosures.
