A plastic panel has a central row of openings, each having a forwardly facing shelf at one end, a plurality of rearwardly directed posts having forwardly facing shoulders, a plurality of projections proximate the respective openings, each projection having a forward facing shoulder a plurality of resilient latches integrally molded in the panel, and lateral sidewalls extending rearwardly well beyond a main body portion of the panel, the sidewalls being parallel to the row of openings. A bus bar selected from two different width bus bars has a plurality of holes to be disposed over the posts and a plurality of branch circuit fingers extending transversely to the bus bar. Attachment of the bus bar to the panel is accomplished by pressing the bus bar over the posts against the latches to depress the latches and subsequently sliding the bus bar toward the row of openings to engage the distal ends of the branch circuit fingers with the shelves, the leading edge of the bus bar with the forwardly facing shoulders of the projections and edges of the holes with the forwardly facing shoulders of the posts, and to release the latches to engage an edge of the bus bar to retain the bus bar in engagement with the aforementioned shoulders and shelves.
