Been a long time since i have done any actual electrical design and want to make sure i am doing this correctly.
I have 480VAC 3 phase available and i need a transformer that can supply me with 120VAC single phase(one line with neutral) at 20 amps on the 120VAC side. So my old school math says a 3KVA transformer will be good like this one:
acme Item Number CE3000F007
Does this sound correct? I would wire the primary side with L1 and L2 to H1 and H4 (leaving L3 out) from the available 480vac. then on the secondary side i would use X1 and X2 for my output.
