An enclosure for electrical installations includes a bottom part and a cover hinged to the bottom part, the bottom part including a first top edge with a first fastener including a first recess and a first platform for receiving a hinge of the enclosure in a form-locked manner, and a second top edge with a second fastener including a second recess and a second platform that permits the receipt of the hinge of the enclosure in a form-locked manner, and the first fastener and second fastener are arranged on respective top edges of the enclosure to be diametrically opposite each other. In order to hinge the cover on the desired top edge of the bottom part of the enclosure and to provide the locking of the cover to the bottom part with a turnable latch, the first platform forms a first cavity on a first inner wall of the bottom part of the enclosure for receiving the latch, and the second platform forms a second cavity on a second inner wall of the bottom part of the enclosure for receiving the latch.
