How is a receptacle outlet defined?

A receptacle outlet is defined as an outlet designed to receive a plug and supply electrical power to devices. This definition accurately captures the primary function of receptacles, which is to provide a point of connection for electrical devices to access power.

By allowing devices to plug in, receptacle outlets facilitate the distribution of electrical power for a wide range of appliances and tools, making them essential in residential, commercial, and industrial settings. This is distinct from outlets that serve other specific functions, such as direct connections to the main power supply or those limited to lighting fixtures. The versatility and utility of receptacle outlets are why they are such a common feature in electrical installations.
