Abstract
A method and arrangement are provided for power operation of manually operable switchgear. The capability for power operation may be provided either during manufacture or as a retrofit to installed switchgear. The apparatus includes a switch-operator unit which is attached to the switchgear. In a preferred embodiment, the apparatus includes a device for providing power to a rechargeable power supply of the switch-operator unit from the energized portions of the switchgear; the power-providing device being efficiently installed in either a field retrofit operation to installed switchgear or during manufacture of the switchgear. The apparatus also includes provisions for providing operating power from the rechargeable power supply of the switch operator to a second, separately housed switch-operator unit that is attached to the switchgear.
