NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association. These NEMA L21 twist-lock plugs have a voltage rating of 120/208Vac and come in 20A and 30A versions. The twist-lock plug guarantees a more reliable connection, where vibration or incidental impact could disconnect a normal plug. Ideal applications of the NEMA twist-lock plug are in industrial and commercial settings.
