Abstract: A modular office wiring system comprising a power distribution module, at least one data hub, at least one ten-conductor high-voltage cable, a cable carrier, connectors, at least one power core, at least one high-voltage power module, and at least one low-voltage data module. The system may additionally include one or more splitters that provide branch power lines, with additional power cores positioned on the branch lines and additional high-voltage power modules and low-voltage data modules connected to the additional power cores. In addition, a method is provided for installing and uninstalling the modules to each other.
