How do you calculate current into Altivar ATV56 drive so that he can size his feeder (breaker), the AIC rating of his system is over 22 KAIC?

The ATV56 is not rated for a system with KAIC over 22. He should either use a 3 % line reactor to bring the system down to acceptable level and then size the feeder using the local electrical code such as 115% of the input current of 61.2 amps.
