This electrical riser diagram outlines the grounding infrastructure connecting the main switchboard to various building elements using #3/0 copper conductors. The neutral bus and equipment ground bus at the main switchboard tie into multiple grounding electrodes and bonded systems. A #3/0 copper conductor runs to the structural steel of the building for structural grounding. Another #3/0 copper conductor connects to the cold water pipe system upstream of the water meter. A separate connection extends to the reinforcing steel in the concrete foundation. Additionally, a #3/0 copper conductor routes upward to supply the first floor server room ground bus.
