ABSTRACT:
A hollow bus bar connector for use with cable conductors of a power distribution system. The bus bar includes a plurality of terminals extending from a common bar for mechanically engaging and electrically connecting said terminals to said bus bar connector. The bus bar is formed in a casting operation in which a plurality of cores are respectively provided in the terminal and common bar portions of the connector. The resulting casting exhibits a uniform hollow cross-sectional area in which shrinkage of and porosity in the external surfaces of the connector are substantially avoided. Accordingly, the resulting bus bar connector is lighter in weight and the external surface thereof provides for a more uniform application of insulation to the connector.
