The software automatically creates a feeder circuit when you associate a load or any equipment item with a bus. This automatic creation of feeder circuits occurs when you do one of the following:

  • Drag a load or an equipment item from the Electrical Index to the Electrical Engineer.

  • Drag a load or an equipment item from one bus to another in the Electrical Engineer.

  • Select the Create circuits option on the Batch Load Association dialog.

  • Select the Create circuit option on the Feeder Data tab of the Common Properties dialog for any motor, static load, converting equipment, and other equipment.

  • Select a PDB, bus, and cell without selecting an existing circuit on the Feeder Data tab of the Common Properties dialog for any motor, static load, converting equipment, and other equipment.

Whenever you associate a load or an equipment item with a bus for the first time by dragging an item from the Electrical Index to the Electrical Engineer, the software automatically creates a feeder circuit for the dragged item. Also, whenever you change an existing association in the Electrical Engineer, the software automatically creates a new feeder circuit and circuit components on the bus to which you dragged the load or equipment item. In this case, the old feeder circuit that belonged to the dissociated item remains in its original place. You can delete it if you want to or leave it as a spare feeder circuit to associate with another equipment item.

Regardless of whether you drag a load to a bus from the Electrical Index to the Electrical Engineer or within the Electrical Engineer, the software also creates circuit components for the new feeder. In this case, you must ensure that you define the cell properties correctly. In the Properties window for a cell, select the In Use setting for the Cell Usage property. When dissociating the last load from a circuit, select the Installed Spare setting for the Cell Usage property.

Note the following:

  • If the load that you drag is associated with a typical circuit, the software creates the necessary circuit components as they are defined in the typical circuit.

  • If the item that you drag is not associated with a typical circuit, the software creates a feeder circuit without any circuit components.

  • If the item that you drag is not a load, the software creates a feeder circuit without any circuit components.

Also, you can instruct the software to automatically create a feeder circuit and a cell when you set the Feeder options on the Common Properties dialog of any load or equipment item. You also can do this when associating loads with buses in batch mode. For more information about batch load association, see Associate Loads with a PDB in Batch Mode.
