An adjustable cover for outdoor electrical substations is disclosed. The traditional metal cover for these installations is capped with length adjustable fiberglass reinforced plastic cover pieces. The cover pieces slide over one another in an interlocking relationship to accommodate the top surfaces of a variety of existing electrical substations. Once in place the covers are maintained in the same interlocking plane to the top surface of the substation with their cooperating flanges insuring positive prevention of weather related water damage to sensitive electrical components. End caps further enhance the degree of water damage protection.

[What is claimed is:] [17.](a) a main cover having a top surface, left and right side walls and a first and second end, said main cover being longer in length than in width, said main cover top surface and said main cover side walls defining a generally "C" shaped opening at each end of said main co
[What is claimed is:] [17.](a) a main cover having a top surface, left and right side walls and a first and second end, said main cover being longer in length than in width, said main cover top surface and said main cover side walls defining a generally "C" shaped opening at each end of said main cover;(b) said "C" shaped opening at at least said first end of said main cover having a first flange, said first flange extending a spaced distance inwardly from said main cover top surface and disposed perpendicular thereto, said first flange being confluent with a second flange extending a spaced distance inwardly from each of said left and right side walls, said second flange being disposed substantially perpendicular to each of said main cover side walls;(c) said main cover having at least a first pair of support bars having a predetermined first height, said main cover support bars including a lower surface for contacting the top surface of the substation, when said main cover is in place on the top surface of the substation said support bars affixed between said main cover side walls, said support bars being positioned perpendicular to said main cover side walls;(d) an extender cover having a top surface, left and right side walls and a first and second end, said extender cover top surface and said extender cover side walls defining a generally "C" shaped opening at each end of said extender cover, said extender cover "C" shaped opening at at least said first end of said extender cover having a third flange, said third flange extending a spaced distance outwardly from said extender cover top surface, and substantially perpendicular thereto, said third flange being confluent with a fourth flange extending a spaced distance outwardly from each of said extender cover side walls, and substantially perpendicular thereto; (e) said extender cover having at least a second pair of support bars having a predetermined second height, said extender cover support bars including a lower surface for contacting the top surface of the substation when said extender cover is in place on the top surface of the substation, said second pair of support bars affixed between said extender cover side walls, said second pair of support bars being positioned perpendicular to said extender cover side walls, said predetermined first and second height of said main cover support bars and said extender cover support bars respectively, exceeding the height above the top surface of said electrical substation of any protrusions jutting therefrom, thereby maintaining said main cover and said extender cover in a linear parallel plane with said top surface of said electrical substation;(f) said extender cover being narrower in width than said main cover; said extender cover top surface, said extender cover side walls, and said third and fourth extender cover flanges being configured so that when said adjustable cover is placed over said top surface of said electrical substation, and said respective support bars are disposed upon the top surface of the substation said first end of said main cover is positioned over said first end of said extender cover, the predetermined first and second heights of said support bars affixed to said main cover and said extender cover dispose each of said covers above the top surface of the substation whereby the inwardly extending at least said first flange of said first end of said main cover overlap the outwardly extending at least said third flange of the first end of said extender cover, and whereby said main cover and said extender cover are maintained in substantially parallel planes to the top surface of the substation by avoiding said protrusions jutting out from the top surface of the substation, said extender cover being slidably adjustable within said main cover for a differing length of said electrical substation, whereby said main cover top surface, said main cover side walls, and said first and second flanges at said first end of said main cover cooperate with said extender cover top surface, said extender cover side walls, and said third and fourth flanges at said extender cover first end to prevent weather generated water from gaining access to said electrical substation.
