High Quality Content by WIKIPEDIA articles! NEMA connectors are AC power plugs, that is connectors used for mains electricity (in North America and other countries) that conform to the standards set by the U.S. National Electrical Manufacturers Association. Some types are found in nearly all buildings in the United States. Similar and interchangeable connectors are used in Canada, Mexico and other countries using the same type of receptacle, although there are some exceptions. NEMA wiring devices are made in current ratings from 15 to 60 A, and electrical potential (voltage) ratings from 125 to 600 V. Different combinations of contact blade widths, shapes, orientation, and dimensions give non-interchangeable connectors that are unique to a particular voltage, current capacity, and grounding system. NEMA 1 (two prong) and NEMA 5 (three prong) are used for commonplace domestic equipment; the others are for heavy duty or special purposes. The dimensional standard for electrical connectors is ANSI/NEMA WD–6 and is available from the NEMA website.
