Which of the following describes a wiring device utilizing blades that establish a connection with a receptacle?

The option that accurately describes a wiring device utilizing blades to establish a connection with a receptacle is a plug. Plugs are designed with metal blades that fit into corresponding slots of a receptacle, making the electrical connection necessary for powering devices.

This design enables power to flow through the blades of the plug to the connected device, which is why plugs are vital components in electrical systems. They are intended to be easily inserted and removed from receptacles, facilitating the connection and disconnection of electrical devices safely.

In contrast, a receptacle provides the socket or opening where the plug is inserted, and a connector typically refers to a device used to join two or more electrical components, which might not specifically involve the blade design common to plugs. A socket usually refers to a similar component as a receptacle but might not imply the active role of connecting and engaging with a plug.
