Abstract
A terminal assembly for connecting a line cable to the bus conductor of a circuit interrupter or similar device by means of a locking screw that extends through the top wall of a metal lug component and clamps the inserted ends of the cable and bus conductor in overlapping relationship with each other and positive electrical contact with the bottom wall of the lug component. The bus conductor is held in slip-fitted interlocked position at the bottom of the lug component opening by the coaction of a pair of undercut grooves in the side walls of the lug component that accommodate the side edges of the bus conductor and cooperates with a coupling screw which extends through the bottom wall of the lug component and engages an unthreaded hole in the inserted end of the bus conductor. The lug component is fabricated from a block-like piece of extruded metal or, alternatively, from a piece of strap-like metal stock that is bent into hollow-rectangular form and provided with a pair of inturned arcuate tabs or inwardly protruding circular nibs that provide the same slip-fitting keyed fit with the inserted apertured end of the bus conductor.
