ABSTRACT:
An apparatus for covering electrical equipment which is connected to busbars of a bus system and has a maximum structural height, and wherein the upper sides of the busbars are equidistantly spaced from the clamping faces of holders for receiving and firmly retaining the busbars. A universally applicable cover which is not attached to the individual pieces of electrical equipment, but is adapted to be affixed to the busbars, is provided in that the cover is in the form of a cap having a rectangular cross section and comprising a cover plate and side walls. One pair of side walls extends parallel to the busbars and has an internal height with respect to the cover plate which corresponds to at least the sum of the fastening distance and the structural height. The other pair of side walls projects past the outermost busbars of the bus system and is provided with cutouts at the side facing away from the cover plate, the depth of such cutouts perpendicular to the cover plate corresponding to the fastening distance. Attached to the inner side of the cover plate is at least one holding clamp for interaction with a busbar, with one clamping leg extending behind the busbar and embracing it.
