The invention relates to a box-like structure for an electric center (1) consisting of modular, cellular spaces, which box-like structure for an electric center (1) includes a modularly dimensioned base structure (3), vertical profiles (7, 9) and a roof structure (2) fastenable to it, intermediate plates (5) connecting the vertical profiles (7, 9) with the base structure (3) and the roof structure (2) and beams (8) supporting the roof structure, to the assembly of which casing sections, doors and/or covers (12), side plates (6) and back plates (10) of the box-like structure, panels (4) of electrical devices and fastening elements (11) of conductor rails are fastenable. According to the invention, the vertical profiles (9) incorporated in the electric center box structure are fastened to the structure rotatably for 180 degrees when seen from the top, whereby the depth position of the panels (4) fastened to the profiles is adjustable.
