<p>The box has a base (30) and a framework (20) sliding with respect to each other. Transversal plates fix electrical equipments (40, 41) such as a fuse, to flanges (22) of the framework, and the framework has a peripheral edge (21C) supported against an outer face of a wall. The base is slidingly mounted on the framework such that bottom (32) of the base is adapted to be pushed inside the wall, for being isolated from an assembling plane defined by the plates, after the framework is supported on the wall.</p> |
