An electrical distribution schematic details a metering package connected to a main bus via three current transformers and potential transformers rated for 480 to 120 volts. A surge protective device is connected downstream of a breaker on feeder 14A. The main circuit breaker is rated at 1600 ampere trip and 2000 ampere frame with solid-state trip functions including long-time, short-time, instantaneous, and ground fault protection. A control power transformer is fed from feeder 15A. A number 4/0 bare copper grounding conductor ties the system to earth.
