hey guys whats up.
I am taking a old panel that we have laing around and making a test station. I will be running it with 480 3 phase. There is a step down transformer in it that take 480 to 120 (some one removed the fuses from it so i have to add them back to the primary side). the formula that i have for this is ((KVA*1000)/(E*1.73))*1.25
this is a .85 kva transformer feed from 2 legs of the 480 and i get 1.28 amps now this seem a little low. is this right or is my formula wrong.
