A permanently installed cord connector on a cord pendant is considered what type of outlet?

A permanently installed cord connector on a cord pendant is classified as a receptacle outlet because it is designed to provide a means of connecting a flexible cord to the electrical system in a way that allows for the disconnection of power while ensuring secure electrical contact.

Receptacle outlets typically refer to any outlet that receives a plug or connector to establish a connection to supply power. In the case of a permanently installed cord connector, it serves the same function by allowing the cord pendant to be connected to the circuit, effectively making it a receptacle outlet.

The other options do not accurately describe the function of a permanently installed cord connector. A standard outlet is more generic and not specifically tied to cord connections; an extension outlet typically refers to portable devices that allow multiple devices to plug into one outlet and is not permanent; an environmental outlet generally refers to units designed for outdoor or harsh conditions, which does not apply to standard pendants or cord connectors. Overall, the classification as a receptacle outlet is based on its installed purpose and functionality in supplying power through a cord setup.
