A modular multi-component power distribution system is provided having a plurality of modular components which are configurable into a bus-bar based system, a flexible cable base system and a hybrid configuration wherein the bus-bar and flexible cable components are interconnected together. The components allow for configuration of the power distribution system into a variety of office systems including wall panel systems, desking or freestanding furniture systems and raised flooring systems either individually or in various combinations. The system components include a bus-bar-like power distribution assembly (PDA), branching connectors, flex connectors, which are useable to join power distribution assemblies together, and receptacles which are pluggable into either the power distribution assembly, the branching connectors or the flex connectors. Additionally, the power distribution assembly includes solid-wire electrical conductors which are accessible through multiple groups of plug openings to which any of the connectors and receptacles may be plugged. Still further, the flexible branching connectors are joinable serially together to distribute power and also may plug into the PDAs. The branching connectors further include at least one group of openings on each end to allow for the connection of additional system components like a branching connector or a receptacle.
