Change Cable Definitions

In Electrical Wiring Manager, all project cables are based on a cable catalogue definition. This ensures that project cable properties (size, number of cores, core markings, type etc.) are consistent with a 'real' cable.

Users can reassign another catalogue cable to any project cable at any time. This changes the project cable to have the properties (size, number of cores, core markings, type etc.) of the newly assigned catalogue cable, keeping current terminations for the original cable.

After a cable has been created (and/or terminated), users may change a cable's definition on a cable by cable basis by using the Cable Details window. However, in case multiple cables need to be changed then Electrical Wiring Manager provides a facility for a 'batch' update of cable definitions.

To change the assigned cable catalogue for multiple cables, from the Cable Schedule grid, select each cable record that is to be updated, then select Change Catalogue No. for selected Cables in the Tools section of the List Tools - Cable Schedule tab.

This displays the Select a Cable from Catalogue window:

Note:
Only those cables in the Cable Catalogue that have been marked with 'Allow Use' are shown in this selection list. 'Allow Use' pre-filters the catalogue cables that can be used for the current project. Refer to Cable Catalogue for more information.

To select a new cable type from the Cable Catalogue, either double-click on the desired cable or select the desired catalogue cable record and click Select.

The new Catalogue Cable definition will be applied to the selected cables in the Cable Schedule.

Note:
Frozen cables, and cables on locked drums cannot be edited. Changes will not be saved to such cables. A message is displayed to inform users of this.

Selecting a new Catalogue definition will automatically update the Cable Schedule and each cables terminations (if any) including changing core markings:

• All existing core are re-aligned to the new cables core type and core markings.

• Any additional cores are added to the cable (for example, change from a 1 pair to a 2 pair) and all core terminations are retained.

• Any surplus cores are removed (for example, change a 12 pair to a 8 pair). All terminations are retained, except for cores that are being removed.

• If the cable type changes (for example, change a 2 core + E to 1 pair OAS), cores are aligned based on core type (valid core types in Electrical Wiring Manager are C - cored, E - Earth, OAS - Overall Screen or Shield, S - Group or Individual Screen or Shield). For the example given: old core 1 becomes new core 1 since core types are the same and termination is retained, old core 2 becomes new core 2 and termination is retained. The Earth core is deleted, since it doesn't match the core type of OAS. A new core is added for the OAS.

  Note:
  If a catalogue definition is changed in the Cable Catalogue all the project instances are changed to the new definition automatically ensuring design integrity.
