I'm installing 4 pieces of equipment, each piece is labeled 7.2 Kw. They operate at 208V or 240V 1phase.
I'm looking at installing a new transformer fed from a 480/277V panel to supply a new 208V sub-panel. The manufacturer of the equipment are telling me it's fine to supply the 4 pieces with a 30 Kva transformer as that only totals 28.8Kw.
Now, when you divide 7200/208 I you get 34.6Amps x 4 = 138.4A which would mean a 75 Kva.
What am I missing here?
Thanks.
