ABSTRACT:
A mechanical assist, incorporated in each of one line and one load terminal electric connection of a multi-pole device to a switchboard, comprises a bolted joint wherein the bolt, carried by the device, is constrained against endwise movement relative thereto. The other line and load terminal connections are plug-in types. Rotation of the bolt in each assist produces movement of the device relative to the switchboard, thereby facilitating electrical connection and disconnection, as well as mounting and dismounting thereof. An insulative torque coupler is incorporated in the line terminal assist to facilitate connection and disconnection while the switchboard is live.
