You can add and/or delete grounding and neutral cables in existing single-core cable assemblies. This is possible for all phase arrangements of single-core cable assemblies apart from the DC phase arrangement.

After you add or delete grounding or neutral cables, the software automatically changes the phase arrangement accordingly.

The following table illustrates how the phase arrangement changes once you add or delete a grounding or neutral cable.

  • You cannot add or delete grounding and or neutral cables if the current phase arrangement is DC.

  • When adding a grounding and or neutral cable to a single-core cable assembly that has already been associated with equipment items, the software automatically associates the added cables with those equipment items if the cables that you added belong to the Power cable category.

  • Deleting a grounding and or neutral cable from an assembly does not affect the existing associations in that assembly.

  • Dissociating a grounding and or neutral cable from an equipment item automatically dissociates all the constituent cables in that assembly, including the current-carrying cores. This happens only if the grounding or neutral cable that you want to dissociate belongs to the Power cable category. Dissociating a grounding or neutral cable that does not belong to the Power cable category does not affect the other cables in the assembly.

To change the formation of an existing single-core cable assembly, do the following:

  1. In the Electrical Index, right-click an existing single-core cable assembly.

  2. On the shortcut menu, select Common Properties.

  3. On the Single-Core Cable Assembly Common Properties dialog, select Add or Delete in the Neutral cables and/or the Grounding cables sections.

  4. Select Apply.

    The software creates or deletes the cables in the Electrical Index and changes the phase arrangement accordingly. (See the table above.)
