Abstract
Insulating barriers for flat, confronting C-shaped bus bars with facing, depending end portions are integrally formed with a pair of confronting C-shaped insulating members conforming to the shape of the bus bars and joined by a pair of projections extending between and electrically insulating the facing, depending end portions from each other. Preferably, the insulating barrier is formed with flat linear sections joining the confronting C-shaped members which are then folded to form the projections. The C-shaped insulating members have edge extensions covering the edges of the bus bars. Grippers formed integrally with the edge extensions snap under the bus bars to secure the insulating members in place.
