A busbar corner housing includes outer and inner side walls secured to one another through flanges spaced from the corner bend. This leaves opposed openings that are substantially closed by plate-like corner covers. Each corner cover has a channel that conforms to the configuration of the outer and inner side walls and engages and abuts against the side walls. Each corner cover also includes a passage through which silicone caulking material can be forced to fill the spaces under the corner covers with caulking material, with excess caulking material being extruded out of sliver gaps between the corner covers and side walls to fill the sliver gaps and seal the housing against intrusion of moisture.
