The ground wire must *NEVER* be used as a conductor.  It's there as a
safety measure, should there be a circuit defect.  The neutral is the
return path.  It's common to see a voltage change, when a heavy
appliance is turned on or off, but that should only happen once, not
continuously.  A change that happens several times per second usually
indicates a potential problem.  As I mentioned in another note, aluminum
wiring can cause this behaviour.
