If the load selected for sizing is supplied by a cable that was that was imported from ETAP (refer to Import from ETAP), the layout of the Cable Sizing window is different from those for other loads:

Select the installation method and enter the cable length on the Main, Protective and Neutral tabs.
Note:
If no length is entered, cable sizing may still take place using the default length
entered in the Preferences window, if Zero Length Cable Sizing is enabled in that window. Refer to Options for further information.
Click the Update button on each tab to calculate the relevant cable size and related details.
If no suitable cable is found in the cable catalogue a message is displayed to inform the user of this. Either revise the cable details or add a suitable cable specification to the catalogue.
If a suitable match is found in the cable catalogue, the fields are automatically completed.
Click Save to save these details and exit the window.
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.
