ABSTRACT:
A panelboard bus bar arrangement. The arrangement includes an insulating base pan which is supported upon a steel base pan. The arrangement also includes three bus bars positioned within the insulating base ban and arranged side-by-side in a parallel manner. The distance between the bus bars is maintained relatively small by using an insulating member which shields and insulates the bus bars from each other. The insulating member includes openings which expose only portions of the bus bars, and dividers which separate adjacent openings and increase the cross surface distance between the openings. By increasing the cross surface distance between openings, arcing is inhibited between the openings.
