Sorry, just popped in on this one. You're using a star ground system, right?
The ground from each receptacle comes together at a common point (center of
the star) and a big cable connects from there to the electrical system ground.
Star grounding is the best way to eliminate ground loops caused by
"voltage-to-ground" differences that inevitably occur between receptacles
that are wired in parallel.
