Abstract: A stationary housing for accommodating electrical arrangements, in particular cable-branching arrangements. The housing includes separately produced wall elements which are made of plastic and can be assembled in a positively locking manner on site, a dimensionally stable framework serving as carrier for the electrical arrangements an being enclosed by these plastic parts such that joints are produced on the side walls and the housing roof. The plastic parts are optionally stiffened to a further extent by corresponding profilings or corner enforcements and are formed of glass-fiber-reinforced polyester, polypropylene or polyethylene with appropriate coloring and UV-resistance. One person can easily assemble a housing of this type on site in a few minutes and, if required, dismantle it again for repair purposes.
