I just started my job as an apprentice technician. For the longest time, my supervisor have always been measuring the amp draws of my motor from the outgoing cable from the motor to the electric panel (which is below the full load amperage stated on the nameplate), but one of our clients insist that the way we've been measuring it is incorrect, and the correct way is to measure the amp draw from the cable incoming to the motor's panel from the distribution panel, which shows that the motor is drawing twice the amps of the FLA.
The motor is a 50Hz 11kW motor with 25.5 FLA.
I haven't found any specific references or examples in my google search, and the closest I've seen is this website https://www.hvachowto.com/measure-amps-blower-motor-condensing-fan-motor/
So, which is the correct way to measure the amp draw of the motor configuration?
Thank very much for any help, and I apologize if the question is too simplistic or stupid to begin with.
