The electrical enclosure 10 of the present invention is preferably designed to be positioned outside of a building structure where the electrical enclosure 10 is subject to the weather such as rain, snow, sun and wind. It is therefore important that the electrical enclosure 10 be mounted upon a pedestal 12, 14 to keep the electronics inside the electrical enclosure 10 above the ground surface 11.
The cover 20 is preferably removably attached to the base 30 as illustrated in FIG. 3 of the drawings. However, the cover 20 may be permanently attached to the base 30 to form the housing of the electrical enclosure 10 defining an interior to house the one or more electrical components. The cover 20 may be comprised of various shapes and sizes, but it is preferable that the cover 20 have a lower opening 24 similar in shape and size to the base 30 to provide a snug and substantially sealed connection along the perimeter of the base 30. The cover 20 may be transparent or semi-transparent to allow for viewing of the interior of the cover 20 (to also allow for visual alarms such as lights to be used to indicate an alarm situation such as high water within a sump pit).
The cover 20 includes at least one first aperture 22 that receives a fastener 16 for securing the cover 20 to the base 30. As illustrated in FIG. 3, it is preferable to have at least two first apertures 22 on opposing sides of the cover 20 to secure both sides of the cover 20 to the base 30. The first apertures 22 of the cover 20 are aligned with corresponding second apertures 36 within the outer wall 33 of the base 30 that allow the fasteners 16 to extend through the base 30 into the mounting structure and/or the upper portion of the pedestal 12, 14 to secure the pedestal to the base 30. The cover 20 further preferably includes one or more channels 26 that extend upwardly from the perimeter of the lower opening 24 of the cover 20 along an interior surface of the cover 20 to provide additional space for the head of a fastener 16 that extends through the second aperture 36.
The base 30 is adapted to be attached to an upper end of a pedestal 12, 14. The base 30 includes a support portion 31 that extends generally horizontally between an outer wall 33 that defines the perimeter of the base 30. The support portion 31 is preferably planar and forms a floor for the electronic components housed in the electrical enclosure by the cover 20. The support portion 31 further forms a ceiling for the recessed portion 38 that receives the pedestal 12, 14.
The outer wall 33 extends downwardly from the support portion 31 of the base 30 to form a cavity 35 that receives the upper end of the pedestal 12, 14.

C. Mounting Structure
The base 30 includes a mounting structure that is adapted to attach at least two different types of pedestals 12, 14. The pedestals 12, 14 are typically constructed of plastic (e.g. polyvinyl chloride a.k.a. PVC) such as PVC pipes. The pedestals 12, 14 are comprised of a structure and material that allows for the attachment of the base 30 thereto with conventional fasteners 16 (e.g. metal screws, bolts, threaded fasteners 16). Different types of pedestals includes pedestals having different cross sectional shapes (e.g. rectangular pedestal 12 as illustrated in FIG. 9 or a circular pedestal 14 as illustrated in FIG. 12). In addition, different types of pedestals includes pedestals having different sizes (e.g. different diameters, different widths).
It preferable that the mounting structure is adapted for attaching either a circular pedestal 14 or a rectangular pedestal 12 to the base 30 as illustrated in FIGS. 7 through 12 of the drawings. A single mounting structure may be utilized for attaching two or more types of pedestals, or a plurality of mounting structures may be utilized for attaching two or more types of pedestals. For example, a first mounting structure and a second mounting structure could be attached to the base 30, wherein the first mounting structure is adapted to attach a first type of pedestal to the base 30 and the second mounting structure is adapted to attach a second type of pedestal to the base 30.
The mounting structure is preferably comprised of at least one support member 40a, 40b, 40c, 40d having a first portion 42 having a curved surface 43 adapted to receive the circular pedestal 14 and a second portion 46 having a straight surface adapted to receive the rectangular pedestal 12. The first portion 42 may extend to form a complete circle that receives the circular pedestal 14. The first portion 42 preferably has an interior diameter approximately the same as the outer diameter of the circular pedestal 14 so that a curved surface 43 (interior) of the first portion 42 snugly receives the upper end of the circular pedestal 14. It can be appreciated that the first portion 42 may also have an exterior diameter approximately the same as the interior diameter of the circular pedestal 14 so that the curved surface 43 (exterior) of the first portion 42 snugly fits within the upper opening of the circular pedestal 14.
FIGS. 5, 9 and 12 best illustrate where it is preferable to have four support members 40a-b extending downwardly from the lower surface of the support portion 31 of the base 30. Each of the support members is preferably comprised of a first portion 42 and a second portion 46. The first portion 42 is preferably connected to the second portion 46, however the second portion 46 may be separate from the first portion 42. The first portion 42 has a curved surface 43 that faces inwardly that receives the outer surface of the circular pedestal 14 (or that faces outwardly when being positioned within the interior surface of the lumen of the circular pedestal 14).
The second portion 46 preferably extends from the first portion 42 and has a straight surface that faces outwardly to fit within the interior surface of the upper end of the rectangular pedestal 12. The interior surface of the outer wall 33 preferably is shaped and sized to receive the outer surface of the upper end of the rectangular pedestal 12 thereby retaining the upper end of the rectangular pedestal 12 between the second portion 46 and the outer wall 33. The second portion 46 is preferably parallel with a portion of the outer wall 33 nearest to the second portion 46 as best illustrated in FIG. 5 of the drawings. The distance between the second portion 46 and the outer wall 33 is approximately the thickness of the wall of the rectangular pedestal 12.
One or more of the support members 40a-b includes one or more securing apertures 48 that are preferably aligned with the second apertures 36 within the base 30 to receive a corresponding fastener 16. The securing apertures 48 are further preferably positioned within the second portion 46 of the support members 40a-b, however, it can be appreciated that the securing apertures 48 may extend through the first portion 42.
