ABSTRACT:
An interlocking plug and receptacle mechanism which involves actuating means for operating an electrical device which is environmentally isolated from the atmosphere in an enclosure. The electrical device, specifically a circuit breaker, includes a toggle switch lever which is positionable in at least first and second positions. The enclosure includes a receptacle for receiving an electrical plug. An actuating linkage enables the electrical device to be operated from the exterior of the enclosure. An operating handle is connected with a first lever arm and a pin. A pivotally mounted slide plate has an aperture which receives the toggle switch lever and defines an elongated slot which receives the pin. A locking mechanism is connected with the actuating linkage and receptacle for locking the toggle switch lever in the second position in the absence of a plug fully received in the receptacle. The locking mechanism also locks a fully received plug in the receptacle when the toggle switch lever is disposed in the first position.
