The user can size cables by specifying constraint based on maximum allowable cable voltage drop in percent.
Motor Starting Voltage
This cable sizing calculation program allows you to calculate cable size based on electric motor minimum allowable starting voltage.
Short Circuit Current
ETAP’s cable sizing analysis software can compute the size of the cables based on cable short-circuit capacity to withstand the short-circuit current. The short circuit current can be specified manually or obtained from the short circuit calculation.
