George,
WHOA - I am not sure what kind of electrical system you have in your house,
but I can guarantee (I installed it myself) that the ground buss of my home
is not anywhere connected to the neutral wire buss in my electrical system.
If it were there would be 3 wires going from my electrical service box to
the main breaker where my house and garage main bereakers reside and the to
connection on the meter pole vs the 4 that are going there now. How do I
know there are 4 wires - I pulled each of them through the buried electrical
conduit personally, and hooked them each up myself. Even though I did the
work myself, and I live in the county, I have had a licensed electrician and
Bandera Electric COOP come and check my work and it is absolutely to code as
far as grounds and neutrals are concerned.
The mat and wrist band I purchased at Radio Shack to dissipate static
electricity both suggest that if a ground rod is not available to use the
special plug that comes with the mat/band adn to place it into the ground
part of a grounded electrical socket.
