Silly and simple question for all the electrical gurus (I'm mechanical newbie)
(OP)
We have a single phase 480V to 240/120V transformer being fed from a Motor Control Center by two phases/legs (phase A and C)...if the only load on the transformer is 240V (say 40 Amps) do I then say that phase A has 40A and phase C has 40A? What if there is 120V load? Can this load be on only Phase A? Only on Phase C? Or a combination thereof?

One half of any 240 Volt load will be seen on both primary phases, A and C.
One quarter of any 120 Volt load will be seen on both primary phases, A and C.
