This group contains the device feature classes that make up the electric network. The electric network also includes the Conductor feature class. The Electric_CONN feature class stores flow and connectivity information for the logical topology. Most device feature classes also have predefined label and model feature classes as well. All devices are related to a circuit (FID_CIRCUIT). See also Circuit Feature Class.
