Concerning 'floating grounds':

  I remember a story from a few years back: a NY bank was installing a vast
number of terminals and associated datacom hardware.  Nothing worked.  Finally
a smart EE checked out the building power and discovered that the typical
office area had power coming in from two DIFFERENT mains and there was a
significant voltage drop across the alleged 'grounds'....
