Depends on the loads' power factor, but for power factors of 1 or unity... 200A ? sqrt(3) = 346.4A.On a 208V three phase wye system all loads are 208V single phase. If A-B load is 200A and B-C load is 200A and there is no C-A load. What will the phase current on phase B be?

PS: The C-A load is irrelevant.

Looks good... but assumes the asker knows vector math. If they don't, the equations and solutions (i.e. results) look mighty confusing....

Equations:

IA= IAB? ICA

IB= IBC? IAB

IC= ICA? IBC

Solutions

IA= 200∡120⁰

IB= 346∡- 30⁰

IC= 200∡180⁰

Are you interested in the formulas to use for a non-resitive load?
