The National Electrical Manufacturers Association (NEMA)[1] is the largest trade association of electrical equipment manufacturers in the United States.[2] It was founded in 1926 and maintains its headquarters in Rosslyn, Virginia, just outside Washington, D.C.[3] Its approximately 450[4] member companies[5] manufacture products used in the generation, transmission, distribution, control, and end use of electricity. These products are used in utility, industrial, commercial, institutional, and residential applications. The association’s Medical Imaging & Technology Alliance (MITA) division represents manufacturers of cutting-edge medical diagnostic imaging equipment including MRI, CT, x-ray, and ultrasound products.[6] NEMA also has offices in Beijing and Mexico City.

In addition to lobbying activities, NEMA publishes more than 600 standards,[7] application guides, white papers,[8] and technical papers. Among its major standards are those for AC plugs and recepticles; the NEMA connectors are universal in North America and also used by some other countries.
