First post so go easy on me, and yes im electrically challenged.
I have a large CNC machine shop powered by a 480v Tx feeding a 208v Wye Tx. Our single phase power is connected to the 208v. Awhile back we checked the loads being drawn on all 3 phases coming from our 208 and noticed that they are grossly unequal, one leg has about double the load as the other two. I called the electrician to ask if this is a problem and he replied - not at all, its normal because the single phase is all drawn from one leg. We are experiencing a lot of problems with our machines electronics boards and i highly suspect its a ground or neutral problem but as im no electrician i really dont know and thats a VERY long discussion for another day.
So i am curious if it is sound practice to split the single phase load equally from all three legs rather than run all single phase from one leg. Or is that even possible? From what i gather unbalanced loads on 3 phase is highly inefficient.
