The electrical device box comprises four side walls and a rear wall, each side wall being connected to an adjacent side wall and to the rear wall for defining a generally rectangular housing having a front opening delimited by an edge. The box comprises a set of first tabs outwardly projecting from one of the side walls which is to be set against a side of an adjacent supporting structure. The first tabs are spaced apart and at an equal distance from the edge of the front opening for providing alignment of the box with a front surface of the supporting structure. The box also comprises a set of second tabs outwardly projecting from the same side wall. The second tabs are spaced-apart and at an equal distance from the edge of the front opening but farther from it than the first tabs. The second tabs have a sharp end for either penetrating the side of the supporting structure in case of an integral supporting structure, or providing alignment of the box with an intermediate surface between elements in case of a composite supporting structure. The present box is more versatile than the precedent ones.
