Calculate Multiple Cable Sizes

To calculate the cable size for a multiple cables:

1. Select the cables from the Cable Schedule list, then click Cable Sizing in the Calculations section of the List Tools - Cable Schedule tab.

5. Click Next >.

   Note:
   If user-defined cable sizing equations from a spreadsheet are to be used, check the External Cable Sizing checkbox. Refer to External Cable Sizing for further information.

   For those loads for which cable sizing has already taken place, their cable numbers and lengths are displayed:

   

7. Select the loads that are to have their cables sized by checking the appropriate Accept checkboxes. Check the Select All checkbox to check all the Accept checkboxes.

8. Click Next >.

9. The selected cables are then sized using automatically assigned parameters (length etc.).

   Note:
   The maximum number of cables that may be connected to an equipment item may (optionally) be specified on the More Information window accessed from the Equipment Layout window. If the sizing procedure attempts to connect a cable to an equipment item when the maximum number of cables has already been connected to that item, a message is displayed to inform the user of this.

   Note:
   In the case of parent cables (i.e. cables with child cables), when a cable sizing update will result in the number of child cables changing, the Child Cable Numbering Options window is displayed when the cable is saved:
