PURPOSE:To reduce mounting area by connecting cabinet panel bodies, which include circuit breakers and switches, between main cables and loads so that their housing frames can be turned with turning mechanisms at the side of the cabinet panel bodies. CONSTITUTION:Main cables 5 supported with cable racks 4 are arranged along the wall of a sectioned room 3 and cabinet panel bodies 1 are installed in front of them. The cabinet panel bodies 1 have hollow rotation shafts 16 rotatably supported by upper and lower rotation shaft bearings 18 on the right of housing frames 17 and turn from the positions shown by the solid lines in the Figure to the positions shown by the broken lines. Branch cables 12 are drawn in from the hollows 23 of the upper bearings 18 and drawn out from the hollows 24 of the lower bearings 18 via primary wiring breakers 8, neutral switches 9, and branch wiring breakers 15. Thereby the sectioned room is made shallower, mounting area is reduced, the shorter branch cables are distributed, and the reliability improves. |
