I'm quite new to the engineering field and I was told to check if the sizing for the motor was done correct. The motor was a 214KW 480V with FLA of 330A. I thought that since the motor only had an RPM of 1000, I would need to size the conductor for 125% of the FLA and not the FLC. I was later given the datasheet for the motor and saw multiple power ratings and now I am currently unsure how the power rating was selected for the circuit. I was also then told that it was controlled by a motor drive which has listed the current at 438A. Does the conductor have to be sized for the input current of the VFD for this or am I supposed to use the FLA of the motor?
