You can change an existing electrical association by doing one of the following:
-
Drag an item in the Electrical Engineer to another item in the electrical tree of the Electrical Engineer.
-
In a cable block diagram, connect two items using a cable or a connector. See Working with Smart Data and Auxiliary Graphics in a CBD.
Note that such changes are governed by a strict set of rules.
There are specific rules that govern the change of electrical associations. Note that the software allows you to connect electrical items even if there is no interconnecting power cable between these items. In a way, this is similar to the way loads are assigned to circuits.
The software does not allow you to make parallel connections or change existing parallel
connections of cables in the Electrical Engineer. Parallel cable connections or changes of parallel associations can be carried out
only in cable block diagrams.
The following rules apply when dragging an item within the Electrical Engineer:
|
Source Item |
Target Item |
Result |
|---|---|---|
|
Loads, converting electrical equipment, primary transformer windings, cables, incomer circuits, junction boxes, local panels, miscellaneous electrical equipment |
Feeder circuits, cables |
The source item becomes the child of the target item in the Electrical Engineer. |
|
Bus riser circuits |
Coupler circuits |
The source item becomes the child of the target item in the Electrical Engineer. |
|
Panel - Circuits |
Cables |
The source item becomes the child of the target item in the Electrical Engineer. |
|
Cables |
Panel - Circuits |
The source item becomes the child of the target item in the Electrical Engineer. |
|
Cables, incomer circuits |
Generators, battery banks, UPSs, battery chargers, converting electrical equipment, secondary transformer windings |
The source item becomes the child of the target item in the Electrical Engineer. |
|
Cables associated with loads |
Loads |
The software creates a daisy- chain connection pattern between the loads. |
|
Any item that has an electrical parent item (except for buses) |
The root of the Electrical Engineer tree view |
The software dissociates the source item from its parent item. |
Special Conditions
Changing the association of a terminated power cable by dragging it to another equipment item in the Electrical Engineer, disconnects this cable from the terminal strip of that equipment. The software disconnects the cable without displaying a warning message.
If the dragged item has no hierarchical parent item:
The system creates a new relation with the parent item.
-
The system copies all the existing associations from the target item to the dragged item. The copied associations include the highest item in the hierarchy, such as a load or an incomer circuit.
If the dragged item has a hierarchical parent item:
-
Dragging it to another item that is not its parent item dissociates the dragged item from its current parent item.
-
The dragged item acquires a new electrical relation with the item to which it is dragged. The copied associations include the highest item in the hierarchy, such as a load or an incomer circuit.
-
The system copies all the existing associations from the target item to the dragged item. The copied associations include the highest item in the hierarchy, such as a load or an incomer circuit.
-
You can connect electrical items in a daisy-chain pattern. For more information, see Create a Daisy-Chain Connection Pattern.
