What is an outlet that contains one or more receptacles called?

An outlet that contains one or more receptacles is referred to as a "Receptacle Outlet." This designation is in alignment with the terminology defined in the National Electrical Code (NEC). A receptacle outlet permits the connection of a plug which is designed to provide electrical power to devices and appliances. By specifying "receptacle outlet," the definition emphasizes the function of the outlet as the point where electrical devices can be plugged in, making it clear that it serves as a direct connection point for electrical circuits.

The term itself distinguishes it from general terms that might signify other types of outlets. Other choices like "Plug Outlet," "Power Outlet," and "Utility Outlet" do not accurately reflect the terminology used in NEC for an outlet specifically designed with receptacles. Understanding this precise terminology is essential for anyone studying the NEC, as it aids in clear communication and understanding of electrical systems and their components.
