National Electrical Manufacturers Association (NEMA)
National Electrical Manufacturers Association (NEMA) sets standards for a wide range of electrical products, including motors. National Electrical Manufacturers Association (NEMA) is primarily associated with motors used in North America. The standards developed represent the general industry practices and are supported by manufacturers of electrical equipment. These standards can be found in the NEMA Standard Publication No. MG 1. Some large AC motors may not fall under NEMA standards. They are built to meet the requirements of a specific application. They are referred to as above NEMA motors.
