Abstract
Abstract A power panel for use with wall panels of a space-divider system includes a lightweight frame structure having vertically extending end plates and a central web. Front and rear spaces are defined on either side of the web to accommodate electrical and communication wiring and receptacles on both the front and the back of the panel. A rib, extending from the web, divides the front and rear areas and provides physical separation between electrical power and communication wiring. The portion of the web on one side of the rib has an offset curved section to accommodate electrical wiring conduits extending vertically from the top to the bottom of the power panel. The power panel includes an upper area, with a removable cover, above the upper edge of the frame structure to accommodate wiring to and from, and between wall panels adjoining the power panel. A U-shaped cover is removably attached to the lower edge of the frame structure to accommodate wiring to and from, and between, panels adjoining the power panel. Snap-fit removable covers are attached to the front and back of the frame structure. The removable front and back covers and removable upper and lower covers provide easy access to the wiring in the power panel, which accommodates wiring in both the horizontal and vertical direction. The power panel accommodates receptacles on both the front and back in a back-to-back relationship, without increasing the thickness of the power panel beyond that of the standard wall panel, thereby providing an aesthetically pleasing arrangement.
