Bill,
I certainly agree that an ungrounded energized module frame could be 
bad news. Have you EVER seen one? Has anyone else? It seems to me 
that the likelihood of an internal short causing that to happen is 
almost nonexistent. True, a connecting conductor could rub the 
insulation off and short to a frame (another reason to use flexible 
nonmetallic conduit instead of MC cables) but that makes the same 
case for NOT grounding the module frames.
Best, bob-O
