An electrical one-line diagram shows a metering package connected to a feeder with a 600 ampere trip and 600 ampere frame circuit breaker featuring solid-state trip unit with long-time, short-time, instantaneous, and ground fault protection. Three potential transformers provide 480 to 120 volt transformation through a control power transformer and fuses to the metering package. Three current transformers monitor the circuit phase conductors, and a number 4/0 bare copper ground conductor connects the system to earth.
