Founded in 1926, National Electrical Manufacturer Association (NEMA) is an ANSI-accredited Standards Developing Organization made up of business leaders, electrical experts, engineers, scientists, and technicians.
NEMA is the largest U.S. trade organization representing manufacturers of products used in the generation, transmission, distribution, control, and end-use of electricity. Many of NEMA's 350+ standards have been approved as American National Standards or adopted by the federal government.
