Type the cable size in wire gauge units.
Wire gauge expressed in AWG is convertible to kcmil. However, because AWG only goes to 4/0, anything above that cannot be converted from kcmil to AWG. If you have a situation where the wire gauge is larger than 212 kcmil (4/0 AWG), and specify that the value is converted from kcmil to AWG, the software will display <Undefined> for the size.
