Abstract: The invention relates to a parallelepipedal framework (1) of an electrical panel or enclosure comprising: a first rectangular base (b1) and a second rectangular base (b2) each formed by four rails (10, 11), four lateral rails (12, 13, 14, 15) perpendicular to the bases and connecting the two bases together, forming four lateral faces (f1, f2, f3, f4) parallel in twos, two first parallel lateral faces (f1, f3) each comprising an oblique rail (16, 17) fastened along a diagonal of the said face, the four lateral rails (12, 13, 14, 15) and the two oblique rails (16, 17) comprising fastening ends articulated on each of the two bases (b1, b2) arranged to cause the said oblique rails (16, 17) and lateral rails (12, 13, 14, 15) to pivot on two planes formed by the said first lateral faces (f1, f3) so as to be able to maneuver the framework between a folded position and an unfolded position.
