Define Custom Basic Ampacity for Cable Sizing - Intergraph Smart Electrical - Help - Hexagon

Smart Electrical allows you to calculate cable sizing using a custom basic ampacity values that you define in lookup tables. You can select a custom routing method from the Routing list on the Sizing Data tab of the Cable Common Properties dialog. After you select a custom routing method, the software calculates the custom basic ampacity value based on the data that exists in the custom basic ampacity lookup table. The software displays the calculated custom basic ampacity value on the General tab of the Cable Common Properties dialog.

Prior to sizing a cable using this method, do the following to preliminary steps to customize basic ampacity:

1. Update the Routing select list on the Sizing Data tab of the Cable Common Properties dialog and add new custom installation method values:

   1. On the Smart Electrical menu bar, select Tools > Update Select Lists.

   2. On the Update Select List dialog, select Routing from the Selected list.

   3. Add the new routing method select list values as needed and select OK.

      Do not modify or overwrite the existing InAir or UnderGround select list items.

2. In Options Manager, open the General Settings and define the name of the new custom basic ampacity lookup table. You can add as many new custom basic ampacity lookup tables as you need.

3. In Smart Electrical, create a new lookup table with the same name.

   

   1. In the Reference Data Explorer, expand the Lookup Tables folder.

   2. Right-click the Cables folder and select New Lookup Table.

   3. Make sure that the name the new lookup table is exactly the same as it appears on the General Settings in Options Manager.

4. Populate the new lookup table with your data.

   

   • For more information on how to define your lookup table, see Example of a Custom Basic Ampacity Lookup Table.

   • The software does not validate the changes made to custom basic ampacity lookup tables.

   • The software does not provide the means to synchronize the lookup tables with the associated cables.

   • When copying an electrical network from the Reference Electrical Engineer, the software does not copy custom installation methods that are defined in the Routing select list.

You can now use your custom basic ampacity to size cables. For details, see Use Custom Basic Ampacity to Size Cables.
