Ron I have always had a hard time understanding why moving the point the grounded conductor becomes also the common conductor would make a difference to power quality.
I understand the issue of overloading the common conductor by harmonic currents. That can be avoided by either not loading each leg of the circuit heavily or using a larger neutral conductor.
Assuming we have done one of the above, would there be any other power quality issues?
