Just wondering if someone out there could assist me with this question...
A three phase motor with a FLA of 14A , service factor of 1.15 and PF of .8 lag, is connected to a 460V, 60Hz supply. A capacitor bank of 2386 VAR is connected to the load side of the motor controller at the motor terminals. Calculate the maximum setting of the overload device in this controller.
I want to say 17.5A (14x1.25) but that is not the answer and I can't figure out how to include the capacitor bank in the formula as it should be decreasing the current draw and increasing the PF, any help would be great, thanks.
