Typically electric motors, although they can also be fuel-powered, ¼ hp motors are regulated and have standards as established by the government such as with the National Electrical Code (NEC 70) or the Occupational Safety and Health Administration (OSHA), as well as non-government associations such as the National Electrical Manufacturers Association (NEMA).
