Changing one of the following properties automatically switches on (selects) the Sizing required check box on the General tab of the Cable Common Properties dialog.
Plant Cable Properties
(The properties of the power cable itself that needs to be resized)
The software automatically recalculates the voltage drop after you change one of the cable property values for a cable that has already been sized. If the value you enter exceeds the sizing parameters of the current cable, you will need to resize the cable by selecting the Calculate Sizing button on this tab. The software displays an appropriate message to this effect in the Calculation information box on this tab and turns on the Sizing required flag on the General tab of the Cable Common Properties dialog.
