Abstract
Abstract Apparatus for remote closing of fuse circuits for overhead power lines is described which has a body fabricated of insulating material for detachable engagement with a fuse tube, the apparatus having a handle with a head thereon extending therefrom with a cord attached thereto and extending to the ground. The handle is positioned in the apparatus and the cord pulled for swinging the fuse tube so that the fuse tube is moved to a position for closing a circuit, thereby rendering it unnecessary to close a transformer or tip switch from the pole or from a bucket truck. The apparatus normally slides off the fuse tube in closed position but can be removed from the fuse tube by pulling the cord from the ground.
