1. In a substantially freestanding space divider system formed from a plurality of series-connected upright prefabricated panels, some of said panels having a pair of electrical power blocks fixedly mounted thereon adjacent the opposite lower corners thereof and disposed substantially between the opposite sidewalls of the respective panel, cable means extending interiorly of the respective panel and electrically connecting together the pair of said power blocks as associated with said respective panel, some of said power blocks having a conventional electrical receptacle associated therewith and opening outwardly through the panel sidewall for permitting a conventional electrical plug to be inserted therein, flexible electrical connector means extending between the power blocks of adjacent series-connected panels for electrically connecting the power blocks together, said flexible connector means including connector parts disposed adjacent the opposite ends thereof and adapted for releasable electrical engagement with the connected power blocks, each connector part comprising one-half of a separable plug-type electrical connection, the other half of said plug-type electrical connection being integrally associated with the power block, and a power supply conduit releasably electrically connected to a selected one of said power blocks for supplying electrical energy to said series-connected panels, said power supply conduit having a connecting portion releasably engaged with said selected one power block, said power supply conduit having the other end thereof connectible to an electrical potential source, comprising the improvement wherein said power supply conduit includes five electrically conductive wires terminating in said connecting portion, each said power block having at least five electrical conductor members positioned therein and electrically insulated from one another, the five conductor members of said selected one power block being respectively and individually electrically connected to a selected one of said five wires, said flexible connector means including at least five internal conductive elements extending between and electrically connected to said connector parts, the receptacle associated with a first said series-connected panel being connected to a first pair of said conductor members as associated with the power block of the respective panel so that said receptacle as connected defines a first electrical circuit, the receptacle associated with a second said series-connected panel being connected to a second pair of said conductor members as associated with the power block of the respective panel so that said last-mentioned receptacle as connected defines a second electrical circuit which is different from said first electrical circuit, light fixture means mounted on at least one of said series-connected panels adjacent the upper edge thereof, an elongated electrical conductor connected to said light fixture means and extending downwardly through the interior of the respective panel and terminating in a pluglike connection means which is releasably engaged with the power block of said panel, said power block having connecting means associated therewith for releasable engagement with said pluglike connection means, said connecting means being connected to a third pair of said conductor members so as to define a third electrical circuit which is different from said first and second electrical circuits, whereby said lighting fixture means is connected to said third electrical circuit.
