Ampacity Wire Sizing
The required wire size of a service
conductor can be determined based on
the specified electrical requirements
and the [WireSz] key. The wire size is
automatically recalculated whenever
the wire insulation (temperature) ratings
or wire material (copper or aluminum)
types are revised. Wire sizing is based
on the requirements defined in NEC
Tables 310-16 and 310-17.
