The electrical equipment housing has a base (1) carrying a support rail (10) that accepts the electrical equipment. The support rail is fixed to the bottom of the box by a pin (9) in the centre of the rail. The pin allows the rail to rotate. The extent of the rotation is limited by a clip (6) that fits over one end of the rail, and at the other end by a screw (13) that passes through a slot in the end of the rail and engages a hole in the bottom of the box. These two fixings also limit the lateral movement of the rail. |
