position that connects related poles of an electrical circuit.

RECEPTACLE, CLOCK -A flush receptacle having a recessed cord-storage space in an integral

flush-device cover plate, commonly used with wall clocks.

RECEPTACLE, DISPLAY -A flush receptacle provided with a flush device plate or outlet box

cover and closure plug or plugs that is intended for use in show window floors and similar locations where the device is not likely to be subjected to scrub water.

isolated from the system ground when installed in a metallic outlet box or raceway system.

RECEPTACLE, SELF-CONTAINED -A receptacle which includes an enclosure and mounting

means intended for flush mounting without the use of a separate flush-device or other outlet box and for connection to one or more nonmetallic sheathed cables containing copper conductors in accordance with National Electrical Code, ANSI/NFPA-70.
