Divide by the rated full load current from the motor nameplate. This will be the load factor for the motor. If the motor current is 22A and the rated full load current is 20A, then the load factor is 22/20 = 1.1. This means the motor is overloaded by 10%.
WebMotor overload devices, which are generally located in the motor controller, are permitted by Section 430-32 (a) (1) to be sized according to the marked "service factor" of the motor. These values are generally 115 percent or 125 percent of the motor FLC. There are exceptions to this as shown in Section 430-32 (a) (2).
