Abstract
A fuse cutout switch (12) attached to electrical distribution equipment mounted on poles of electrical distribution systems operable with hooksticks (16) in which a connection assembly (28) detachably engages a first distal end of a fuse body (20) that is pivotably and detachably engaged at a second distal end to a hinge (22). A grab member (32) attached to the fuse body (20) near the first distal end includes a receptacle (36) for selectively receiving the hookstick (16) for disengaging the fuse body (20) from the connection assembly (28). A restoring member (40) attached to the fuse body (20) near a second distal end has a receptacle (42) for selectively receiving the hookstick (16) for pivoting the fuse body (20) about the hinge (22) and engaging the fuse body (20) to the connection assembly (28). Various embodiments of the grab member and the restoring member are disclosed, together with methods of modifying existing fuse cutout switches and of operating a fuse cutout switch.
