[Elecraft] ESD Protection for K3 Assembly

[Don Wilhelm]

Phil,

Connection to the AC ground should be adequate and safe - if a 
receptacle is properly grounded, remove the screw in the center of the 
cover plate and attach a terminal lug there.

If your station ground is connected by a heavy guage wire to the Utility 
Entry ground point, then I will agree with your that the station ground 
will do.

We all know that there are references to "station ground" that are 
connected to driven ground rods that are NOT connected to the Utility 
Entry ground.

   I need to point out that not only is that a violation of NEC 
grounding requirements, but it presents safety hazards for anyone in 
contact with that station ground under AC wiring fault conditions. All 
grounds must be connected together except for structures separated by 
100 feet or more.

See the 2010 (or later) ARRL Handbook for further information.

I apologize if this sounds like a rant, but it is not - it is concern 
for the safety of each and every ham.

73,
Don W3FPR
