ABSTRACT:
An electrical set screw connector has an insulating cover over a metal body which includes conductor receiving passages or ports and intersecting set screws adapted to clamp down on conductor ends in the conductor receiving passages or ports. The connector insulating cover includes a vestibule or tubular chamber for each set screw. The outer end of the vestibule is restricted to capture the screw and each vestibule is internally threaded. The outer end of each vestibule includes a drive hole for the set screw. The connector insulating cover is made by dipping using the backed out set screws as core pins for each set screw vestibule with removable shanks in the set screw recesses forming the drive holes.
