A universal power distribution system is provided for routing electrical circuits within a building structure to comprehensively provide electrical power to the building in ceiling configurations, wall-mounted configurations, raised floor configurations and in office furniture configurations. The system components for all of these configurations have common plug connectors that are engagable with each other so as to be readily usable in a wide variety of applications. The system is readily adaptable to form virtually any conventional circuit configuration found within conventional hard-wired systems yet is formed simply through the routing of the cables through the building cavities and interconnection is accomplished merely by plugging components together rather than through labor-intensive manual wiring.
