Wire Size Section
Each row in the grid lists a wire size in the current group.
Size: A description of the size of the wire. This value is for informational purposes and is used when selecting the wire in other dialog boxes. It is also used in the feeder callout.
Wire + Insulation Area: The area of the wire with insulation. The wires are sorted based upon the area. Used to calculated the conduit fill.
The units for this value are left undefined intentionally. The default values are square inches, based upon NEC Table 5. You can use any units you want as long as they match the units used for conduit area.
Wire Only Area: The area of the wire itself, in circular mils.
New: Creates a new wire size. The new wire size will be added to the bottom of the list when it is created. When you close and reopen the dialog box, the size will be sorted to the correct location in the list based upon the area.
