Abstract
A power and signal distribution system is adaptable to existing building areas and provides a shielded, low resistance and low inductance grounding structure. The distribution system comprises two or more electrically conductive enclosed channels; one for lower current signals and power distribution and one for high current signals and power distribution. The enclosed channels are electrically coupled and are configured as crosses or spokes with branches extending substantially over the length and width of the building area. The earth ground for the building has a direct connection to one of the enclosures. The ground of each device in the building area is directly connected to the enclosed channels by a low impedance connection. Cables are routed through the enclosures and extended to the devices. The walls of the enclosed channels have a thickness that is greater than the skin depth of a predetermined low frequency.
