An electrical system for a wall system formed from a plurality of serially connected wall panels. Each panel has at least one electrical terminal mounted thereon, and the terminals are joined by electrical cables or flexible electrical connectors. The electrical system is a seven-conductor system employing three live and three neutral conductors for defining three separate electrical circuits each having a separate neutral. A portable power-tap unit, specifically a receptacle unit, can be plugged into the power block for selective engagement with any one of the three circuits. The power-tap unit has a connector portion which plugs into the power block, which connector portion is defined soley by three contacts. Two of the three contacts, namely the live and neutral contacts, are mounted on a carrier which is slidably supported on the power-tap housing so as to be slidably displaced between three selected positions so that the power-tap can be selectively joined to any one of the three circuits.

A small portable electrical power-tap unit adapted to be releasably coupled both physically and electrically to an electrical terminal by means of a pluglike connection, the terminal having multiple conductors associated therewith defining at least first and second electrical circuits each having separate live and neutral conductors, said power-tap unit comprising: a blocklike housing of electrically insulative material defining a hollow interior therein; first, second and third conductive members mounted within said hollow interior in electrically spaced relationship and having conductor parts which define three individual pronglike receptacles associated with a three-hole electrical socket, said housing having three openings formed in one wall thereof in alignment with said conductor parts for defining said three-hole socket for permitting supply of electrical energy to a circuit or device disposed externally of the unit; a pluglike connector portion associated with a further wall of said housing for permitting said unit to be physically and electrically coupled to the terminal by means of a pluglike connection; said connector portion including first, second and third electrical contacts which are adapted to create releasable electrical engagement with the terminal, said first and second electrical contacts being movably supported on said housing within the hollow interior thereof and projecting outwardly therefrom, said third electrical contact being fixedly supported within said housing and projecting outwardly therefrom; carrier means of an electrically insulative material slidably supported on said housing and having said first and second electrical contacts stationarily mounted thereof for permitting said first and second contacts to be synchronously moved relative to said third electrical contact between at least first and second positions which permit the power-tap unit to be coupled to the terminal for connection to different electrical circuits; electrically conductive means connecting said first and second electrical contacts to said first and second conductive members, respectively, for permitting relative movement therebetween as said first and second electrical contacts more between said first and second positions, said third electrical contact being electrically connected to said third conductive member; said carrier means being movably supported on said housing for slidable displacement in a direction which is substantially perpendicular to the outwardly projecting direction of the electrical contacts; said further wall or said housing having elongated slot means formed therein through which project said first and second electrical contacts for permitting said contacts to be displaced along said slot means between said first and second positions; and said carrier means having fixedly associated therewith first and second shroudlike parts which are also of electrically insulative material and are disposed in surrounding relationship to the first and second electrical contacts respectively, said first and second shroudlike parts projecting outwardly through said slot means and being transversely slidably displaceable therealong between said first and second positions.
