      No starting code letter or Code F to V maximum size 250% of full load amps up to next standard size of breaker. I usually use 200% for motor starting. I = 13.7A for 5HP motor. Circuit Breaker = 2.0(13.7A) = 27.4. CB1 Use 30A breaker maximum which is next standard size higher if motor will start with smaller breaker, it should be used.

      Motor currents: average current (I ave), individual phase and ground current in primary amps and % of full load and % phase unbalance. Motor RTD: individual winding, motor bearing, load, and auxiliary temperatures. Motor: % I2t (thermal bucket used), time until next start can occur, remaining starts and time left on oldest start.

      Jun 17, 2002 · Starting KVA, Starting Power Starting. Motor full load amps from nameplate. See Table 2 Onan book for motor data. Resistive Loads. Resistive loads consist of incandescent lights, water heaters, electric heaters, stoves, and electric furnaces. Power factor = 1, KW = KVA. Running and starting KW are the same.

      Now set the dynamometer control to its full clockwise position to maximize the starting load for the motor. Do NOT adjust the field rheostat. Turn on the DC power supply and increase the voltage control until the motor draws 3 amps of starting current. The motor will turn very slowly or not at all.

      If tripping occurs on motor inrush, adjust settings in increments until motors start without tripping. Do not exceed eight times the motor full-load amperes (or 11 times for NEMA Premium Efficient motors if required). Where these maximum settings do not allow starting of a motor, notify COTR before increasing settings.

      INDUCTION MOTOR STARTING CHARACTERISTICS. OBJECTIVE. To determine starting current and starting torque of a three-phase, wound rotor induction motor. DISCUSSION. In the previous section, it could be observed that the open circuit voltage across the rotor windings varied linearly with respect to the slip RPM of the rotor.
