In residential electrical work, a receptacle is the specific, NEC-defined contact device installed at a wall outlet that accepts a plug. The term is often used interchangeably with “outlet” or “socket” in everyday speech, but “receptacle” is the precise term used in the National Electrical Code and by licensed electricians. A socket is a broader term that applies to any device that receives a plug or bulb, including light sockets. When reviewing electrical diagrams or code documentation, “receptacle” is the correct term for a standard wall outlet.
