An electrical one-line diagram details a metering package with a control power transformer and fused connections tied to a bus. A surge protective device connects downstream through a dedicated breaker unit. Additional switchgear sections include trip unit parameters with 1200 ampere frame and trip ratings, three current transformers, and ground wiring using a #4/0 bare copper conductor. The schematic integrates standard metering and protection components configured for a 480 to 120 volt system.
