Re: Ground rod Connection Point

Jeremy: The realitive differance between copper, brass, bronz, silver or
aluminum is slight. At high current the differance is important. 1000 amps
through 1m ohm is 1 volt and 1000 watts. 1 m amp through the same 1 m ohm is
1 micro volt. With your TC putting out 1 megavolt the loss of 1 micro volt
is of no importance. I have used a ground rod inside my house driven flush
with the floor tapped with a screw hole in the end. The only problem is dirt
and dust in the hole when you make connections.
