[Elecraft] grounding power supply email trail is confusing

[Jim Spears]

K9YC, W3FPR, W4TV and others have certainly raised my interest in the art
and science of "grounding" vs "earthing" in the grand scheme of things as
specified in the NEC and other sources.  But there has been such a
proliferation of messages over several days, the net effect of which is to
leave me massively confused.  Could someone synthesize this into a set of
practical guidelines which are NEC compliant and technically correct.  

 

While surveying the stuff in my shack, I see boxes with two connector
unpolarized plugs, two connector polarized plugs, three conductor plugs with
a ground stud, and three conductor plugs with no ground stud.  In my shack I
have a mix of 240 and 120 vac boxes.  These are on separate circuit
breakers, the main panel is located at the opposite end and one floor up of
a fairly good sized house.  Just for fun, I have copper pipes but the well
pipe is plastic.\
