What do I have to do for this circuit line to be apart of the same subnetwork as the line that is coming from the substation(adjacent) to it. Do I set the transformer as another subnetwork controller on the same subnetwork?<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="a6 circuit from transformer.jpg" style="width: 999px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/147152i27EE0BF9604737FB/image-size/large?v=v2&amp;px=999" role="button" title="a6 circuit from transformer.jpg" alt="a6 circuit from transformer.jpg" /></span></P> Thu, 22 Jan 2026 19:52:19 GMT https://community.esri.com/t5/arcgis-utility-network-questions/transformer-connection/m-p/1679419#M6380 Joshua_Moreno 2026-01-22T19:52:19Z https://community.esri.com/t5/arcgis-utility-network-questions/transformer-connection/m-p/1679424#M6381 <P>Run a subnetwork trace and show where the trace stops. It looks like the transformer is connected up to the third cabinet of the switchgear, which contains a fuse. As long as everything is snapped/connected and the status of the fuse is closed (and phasing is correct, if you're using it) the subnetwork should enter the cabinet in the first bay and exit through bays3&amp;4.</P> Thu, 22 Jan 2026 20:19:37 GMT https://community.esri.com/t5/arcgis-utility-network-questions/transformer-connection/m-p/1679424#M6381 RobertKrisher 2026-01-22T20:19:37Z https://community.esri.com/t5/arcgis-utility-network-questions/transformer-connection/m-p/1679437#M6382 <P>Well, making sure that the fuse is closed did the trick. Overlooked it completely haha, thank you Robert!</P> Thu, 22 Jan 2026 21:33:38 GMT https://community.esri.com/t5/arcgis-utility-network-questions/transformer-connection/m-p/1679437#M6382 Joshua_Moreno 2026-01-22T21:33:38Z https://community.esri.com/t5/arcgis-utility-network-questions/transformer-connection/m-p/1679539#M6384 <P><a href="https://community.esri.com/t5/user/viewprofilepage/user-id/169119">@Joshua_Moreno</a>&nbsp;One of the things I recommend you consider is using a label or symbol to help you easily differentiate an open device.</P> Fri, 23 Jan 2026 14:50:28 GMT https://community.esri.com/t5/arcgis-utility-network-questions/transformer-connection/m-p/1679539#M6384 RobertKrisher 2026-01-23T14:50:28Z
