Ampacity Wire Sizing - Calculated Industries ElectriCalc LT User Manual

Ampacity Wire Sizing

The required wire size of a service con-
ductor can be determined based on the
specified electrical requirements and
the [WireSz] key. The wire size is auto-
matically 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.
Wire Sizing Based
on Insulation Rating
Wiring is being installed in a 240 volt,
single-phase system rated at 30 kVA.
What is the wire size needed if you use
60°C copper wire?
