An electrical sub-metering system for making available information associated with power consumption is disclosed. The system includes an electrical panel board configured to distribute power to a plurality of circuits, means for measuring voltage of each circuit, a module including means for measuring current flow, a hub in signal communication with the module and the means for measuring voltage, and a data collector in signal communication with the hub. The hub is configured to collect the information associated with power consumption from the means for measuring voltage and the module, and the data collector is configured to collect and make available to a user the information associated with power consumption for each circuit. The module is in signal communication with the hub via a single communication link, the single communication link having a plurality of communication paths.
