What is a receptacle in electrical terms?

In electrical terms, a receptacle refers to an electrical outlet designed for connecting devices to a power supply. It typically consists of one or more sockets into which plugs can be inserted, facilitating the connection of various electrical devices such as lamps, appliances, and electronics.

Receptacles are essential components of electrical installations, providing safe access to electrical power in homes, businesses, and other facilities. They ensure that devices can be easily connected and disconnected while maintaining compliance with safety standards, which protect against electrical shocks and short circuits.

The other options describe different components or devices within electrical systems. A circuit breaker functions to protect the electrical circuit by interrupting the flow of electricity in case of a fault. A device that converts AC to DC serves a specific purpose in power regulation and conversion but does not function as an outlet. A safety device for electrical systems encompasses a range of tools and mechanisms, including circuit breakers and fuses, but does not specifically refer to the function of connecting devices to an electrical supply.
