[Elecraft] Anti-Static Grounding - how?

[Stuart Rohre]

Indeed, some house grounds have induced voltages in having long runs back to 
any ground point; and might not be the safest thing to tie your static mat 
to as a "ground" point.  "Ground" in AC systems may have imbalance phase 
currents and be much different from a zero voltage point.  It shouldn't 
ideally, but the real world resistances of wiring carrying heavy current my 
make it so.
