What is indicated if a three-phase motor shows 15 FLA and readings of 15.6, 16.1, and 15.9?

When evaluating the performance of a three-phase motor, Full Load Amperage (FLA) is an important benchmark, as it represents the maximum current the motor should draw under full load conditions. In this scenario, the motor's rated FLA is 15. The actual current readings taken from each of the three phases are 15.6, 16.1, and 15.9 amps, which are all above the FLA rating.

The readings indicate that the motor is drawing more current than it should when operating under rated load. Since the phase readings exceed the FLA significantly, it suggests that the motor is experiencing more strain than intended. This increased current draw could lead to overheating and potentially damage the motor if sustained over time. Therefore, the indication is that the motor is functioning beyond its intended capacity, supporting the conclusion that it is overloaded.
