ABSTRACT:
A group operated circuit disconnect apparatus for overhead electric power lines has a base in the form of a box-like housing which mounts on a pole, an upright shaft extends through the housing, and a transverse shaft also extends through the housing. A linkage is mounted on the shafts in the housing so that axial rotation of the transverse shaft axially rotates the upright shaft, and this causes three circuit disconnect switches mounted on the housing to be moved simultaneously between closed positions and open positions, or vice versa. An electric motor driven screw and nut drive subassembly for the transverse shaft is mounted in the housing; and the ends of the housing have removable closure plates for access to the linkage and for removal of the subassembly.
