A power system is provided and includes an electrical element, feeder lines by which the electrical element is receptive of first signals at first frequency ranges, first and second line replaceable units (LRUs) and first and second communications busses to couple the first and second LRUs to the feeder lines, respectively. The first and second LRUs are intercommunicative using second signals at second frequency ranges via the first and second communications busses and the feeder lines.
