Keyed power cord

1. Field of the Invention An electrical power distribution system for supplying electrical energy to power utilization equipment located, for example, at multiple work stations in a modular furniture installation, has a plurality of power taps, each having an electrical inlet connector, an electrical outlet connector and a power lead for connection to the power utilization equipment. Some of the inlet and outlet connectors are configured differently from others. A plurality of power transmitting jumpers, each having an electrical connector at each of the opposite ends thereof interconnect the outlet connector of one power tap and the inlet connector of another power tap. Certain ones of the jumper electrical connectors are configured differently from other of the jumper electrical connectors so as to connect to only selected ones of the power tap connectors. The differing configurations necessitate interconnection of the power taps in a prescribed order and the number of different configurations effectively limits the maximum number of power taps that can be chained together. A power supply jumper having a power supply plug at one end for receiving electrical energy from a source and a universally configured electrical connector at the opposite end may connect to any one of the power tap inlet connectors to supply power to that and all subsequent power taps.
