An electrical cabinet includes a frame hinge fixed to a frame of the cabinet and a door hinge fixed to a door of the cabinet. The frame hinge forms an insertion window for receiving the door hinge. A hinge pin is inserted through aligned seats of the frame hinge. The door hinge is inserted into the insertion window around the hinge pin. A blocking screw or pin is inserted through a third seat in a direction substantially perpendicular to the hinge pin to block the hinge pin and secure the door to the frame.
