The Electric topology maintains the connectivity between conductors and devices. Use Infrastructure Administrator to configure the topology (which feature classes can be connected with which other feature classes). Use the Connectivity manager to manage the connections in AutoCAD Map 3D or Infrastructure Application Extension . For more information about logical topologies, see Logical Topology Introduction.
Conductors can only be connected to devices, not other conductors. A conductor can be connected to one or more devices, usually one on each end. You cannot connect two devices, for example, a fuse or switch directly to a transformer, you must use an intermediate conductor.
