Were the circuits in your last post "3-wire" or "3-phase"? My understanding is that there is no neutral overloading or harmonic problems with nonlinear loads on 120/240 single phase systems.

The circuits are 3 phase 120/208. Our temp. solution is to rewire the lab w/ dedicated neutrals. Only problem is this pushes the problem to the service conductors feeding the panel that feeds the equipment.
