ABSTRACT:
A channel-shaped insulator is received in a channel-shaped metal track. First and second conductive bus bars are mounted in holders within the insulator, which has wall portions disposed between the track and the bus bars and affording spacing therebetween. The track is formed with first and second longitudinal grooves opposite the bus bars and affording additional spacing between the track and the bus bars. First and second longitudinal ridges are formed on the insulator opposite the first and second bus bars and extending into the grooves for engaging the track to maintain the additional spacing. The depth of the grooves preferably corresponds with the thickness of the wall portions of the insulator between the track and the bus bars. The height of the ridges preferably corresponds with the depth of the grooves. The provision of the grooves and the ridges may increase the minimum spacing between the metal track and the bus bars from 1/32 of an inch to 1/16 of an inch. Additional ridges preferably project from the insulator adjacent the first and second ridges, but spaced laterally therefrom, to prevent shifting of the insulator and to assist in maintaining the additional spacing. Three bus bars may be mounted in holders within the insulator to afford two separate electrical circuits. At least three ridges, are formed on the insulator to project into grooves opposite the bus bars. A fourth ridge is formed on the insulator opposite one of the bus bars to project into the corresponding groove.
