[Elecraft] ESD precautions?

[Don Wilhelm]

I MUST take issue with the statement below, despite any credentials.  If the
AC supply safety ground is not intact, the proper answer is to FIX that.

I can think of any number of equipment problems that could occur at a
workbench that could result in a hot chassis.  When the AC mains safety
ground is intact, such failures result only in a tripped circuit breaker -
BUT if the AC safety ground is not functioning properly AND a person touches
a ground rod connection (or the workbench leg is connected to that ground
rod) all it takes is one quick brush with that live chassis to create
disaster.

So, if you have a non-mains ground in the hamshack or work area, it seems to
me that you should be even MORE diligent about assuring that the AC mains
grounding system is installed and properly functioning.  As has been pointed
out in this thread the outlet ground may not be connected, so do check it to
be certain and re-check it periodically.
Yes, one should not trust it just because that grounding pin is present -
MAKE CERTAIN THE GROUND IS INTACT, YOUR LIFE MAY DEPEND ON IT.

Tom being a electrical contractor I would never depend on the AC supply
safety ground for a ground let alone connect myself to it. The results could
be shocking. I have two separate ground rods driven into the basement floor
here bonded together and separated 8 ft for my static grounds as well as RF
ground. Just too many things murphy can do to make that AC safety ground go
bad. At the very least connect your wrist strap to a metal table leg or
such, that has no chance of becoming energized. Ken W8OB
