Abstract: An electrical enclosure includes a metal body and a metal cover connected by a hinge to each other. The hinge includes one or more integrally formed tubes in the metal body and one or more integrally formed tubes in the metal cover. The body tubes and the cover tubes are aligned in a collinear arrangement and a hinge shaft is located within the body tubes and the cover tubes. The enclosure can have a dual flange structure wherein one of the side walls includes a flat flange and three of the side walls include edge flanges. The enclosure can also have a structure wherein each of the side walls upper portions is connected to its neighboring upper portions and each of these upper portion connections is angled relative to its corresponding side wall corner.

Abstract: A double walled solar shielding system for an electrical enclosure includes an inner enclosure defining a substantially rectangular box with an inner door pivotally mounted to the inner enclosure. A shielding layer extends around the top, rear and lateral sides of the enclosure with a shielding door mounted coaxially with the inner door and having an outer layer spaced apart from the inner door. The doors open independently and may have different security measures. The system includes modular elements and may be retrofitted to existing enclosures.
