[SIZE=11pt]I have a question for you guys. I want to connect a 3-phase 3W+G load bank to two source phases and neutral to force neutral current.  [/SIZE]Although the load bank is internally wye connected, the internal neutral is not accessible since it is designed for balanced load and would not normally produce any neutral current.  So I want to connect the neutral source to one of the phases (only connecting two of the phase sources).  If the load bank resistive elements are set to produce 550kW during balanced operation load at 400V, loading the breaker to nearly 800A, how much load to I get on the load bank and how much current on each leg during unbalanced operation?

 
Is this a question from the exam?  It appears to be very specific.  If from the exam, please remove.
