[Elecraft] ESD precautions?

[kce]

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.
