5.3: Receptacles
Receptacles (Figure \(\PageIndex{1}\)) are one-half of a two-piece multi-contact connector. The other half is the plug. Receptacles vary in shape, size, and application. Most 120 volt residential applications use the duplex U-ground receptacle. In addition, dryer and range receptacles are used in higher-voltage applications. The correct receptacle must be used with the correct plug for each application.
