A multiple-panel switchgear (1) has alignable housings which are limited by side frames (5). A systematic perforation in the side frames (5) comprises alternately disposed larger and smaller holes (6, 7, 13, 14), which, as regards their size, are unsymmetrically disposed relative to a depth axis (10) and a height axis (11). During assembly of the housings, a large hole (6) is located opposite a smaller hole (7). When adapting the holes (6, 7) to thread-forming screws, adjacent housings can be connected on one side only by using screws and tools. Additional holes (13, 14) serve to receive the wiring connecting the adjacent switchpanel. |
