The invention here disclosed is a back wire ground clamp for a wiring device such as a switch or receptacle having a ground strap which supports an outwardly projecting ground lug having a front edge and adapted to receive a ground connection. The ground lug is coupled to a clamp plate by means of a screw which passes through a clearance opening in the clamp plate and is threaded into a receiving opening in the ground lug. The clamp plate supports a blocking tab which extends downward below the front edge of the ground lug and extends side ways for a distance which is less than the length of the front edge of the ground lug. The blocking tab prevents the clamp plate from rotating relative to the ground lug as the screw is tightened and defines an opening between the clamp plate and the ground lug along the front edge of the ground lug into which a single ground wire can be inserted.
