Abstract
An improved support assembly for a circuit-interrupting device is disclosed. The device is of a type having first and second end fittings which define a major axis and which are selectively engageable and disengageable from matching first and second mountings spaced apart in the assembly in insulated relation. The device can be manipulated by a hookstick selectively attachable to the first end fitting and held by a human operator, and so manipulated as to selectively engage and disengage the end fittings and their respective mountings and to open and close the device. The second mounting has a noncircular pin which can be slideably received in a slot in the second end fitting only when the second end fitting and the device are in one particular orientation. The slot contains an enlargement which permits the second end fitting to rotate in the second mounting once the pin enters the enlargement. When the pin is in the enlargement, the device is freely rotatable to both the closed position and the opened position. A cradle, provided on the second mounting for supporting the device, is utilized at two times. First, the cradle supports the device when the second end fitting is being engaged with the second mounting. It performs such support function to automatically place the second end fitting in the one orientation in which it may slideably engage the end fitting. Second, the cradle arrests rotation of, and supports, the device following an opening operation during which the first end fitting is disengaged from the first mounting. Such arresting and support function also automatically aligns the pin in the slot so that the device may be removed from the second mounting.
