ABSTRACT:
Rectangular bus bars alternatively engaged in either of a pair of crossed slots in a support block secured in a panel board are locked in place by a locking device incorporated in a cylindrical terminal portion of each bus bar. The locking device includes an expandable ring seated in a circumferential groove in the cylindrical terminal portion. A pair of actuating pins are urged radially outward in diametrically opposed bores to wedge the expandable ring against the support block, by a tapered screw threaded into a central longitudinal bore in the terminal portion of the bus bar.
