ABSTRACT:
A three phase motor reversing assembly includes two contactors interconnected with solid flat bus bars. The terminal assembly employed on the contactors includes a stationary terminal and a captive threaded fastener slidably retained within a pocket formed from the insulating material of the contactor base. The sliding captive threaded fastener allows the bus bars used for interconnection to be mounted on the underside of the stationary terminal. External connections are made to a cable clamping device mounted on top of the stationary terminal. A bolt is inserted through all of the connections to be made and threaded into the captive threaded fastener. As the bolt is tightened, the captive threaded fastener provides a counter-torque and is drawn up until tight contact is established.
