A retention snap arrangement for attaching a bus bar to a base pan. The arrangement includes first and second walls for forming a channel for receiving the bus bar. The arrangement further includes a first moveable arm having a first snap element that includes a first bottom surface and a second moveable arm having a second snap element that includes a second bottom surface. The first and second arms extend from the first and second walls, respectively, each forming a cantilever.
