Horsepower = 275, Voltage = 460. Chart value of 1.2A/HP multiplied by 275 HP = 330A. 330A X 1.25 = 412.5A. Closest standard current transformer ratio is 400/5. For single-phase motors, determine full load current from the nameplate rating. Multiply by 1.25 to get the approximate CT rating, as shown above. Next Steps:
