Abstract: A system includes an electrical enclosure having an inner volume and a door structured to open to expose the inner volume and structured to close to enclose the inner volume. A racking mechanism is disposed in the inner volume and includes a member movable in a first direction to a first position and an opposite second direction to a different second position. A network protector is carried by the racking mechanism and is movable thereby between a connect position in the inner volume corresponding to the first position of the member of the racking mechanism, and a test position in the inner volume corresponding to the different second position of the member of the racking mechanism. A control mechanism is structured to move the member of the racking mechanism between the first position and the different second position of the member responsive to a number of remote commands.

Abstract: The present invention provides busway plug fitting having a housing assembly and a toggle mechanism disposed therein having at least two operatively linked operating handles. A first assembly is disposed on a first side member of the housing assembly and structured to move between a first position and a second position. The second handle assembly is disposed on a second, perpendicular side of the housing assembly and also structured to move between a first position and a second position. The toggle mechanism is coupled to the external coupling construct of the operating device and structured to move between a first position and a second position. The first and second handle assemblies are operatively linked by the toggle mechanism. In this configuration, a user may operate either handle assembly to actuate the operating device disposed with in the busway plug fitting.
