Hello all! My name is Jason and I reside in Texas. I am studying for my masters exam and am in dire need of some help. I know this question should be a simple calculation but I just am missing something. its extremely frustrating that I don't know this but im very eager to learn and have no one to help me out. Here is the question:
A 3 phase 120/230 Volts Multifamily dwelling building has a total demand load of 220 KVA, What is the minimum size of service conductor that can be used for building?
I know the answer is 600 kcmil aluminum. it also gave me the calculation, but I just cant make it make sense to me.
Full load current I = P / E * 1.732 = (220 * 1000) / 230 * 1.732 = 552 Amperes
Amps = watts divided by the voltage, times 1.732
Am I reading this right? PLEASE HELP!
