Calculating Overcurrent Protection on the Primary Side.


3 KVA dry type transformer (Calculating Overcurrent Protection on the Primary Side)?
I will run #12 THHN wire as we usualy do but the current on the load is some constant at about 1.5 amps for a low voltage power supply and the rest of the panel is floating at about 15 amps max using 480 single phase on the line side of the 3KVA.
Just wondering if I can calculate exactly what the transformer is going to draw?
Thanks
