    So you have multiple grounding rods?

    no, only one.....but it's in the ground maybe 4 feet from my Equi=tech panel. I live in a 'rain forest' climate with what I've been told are ideal soil conditions (it was tested at the time). i do not recall the exact info on my ground rod; only that in desert or eastern US areas the soil conditions are more challenging to overcome.

    My electrician was just here. The panel installation is straightforward.

    We talked about the grounding. Currently I have a copper wire running to my main water line and a second run to a zinc rod in the ground. There is a 2nd rod which attaches to the first rod, 6 feet away, which is required by code.

    It sounds like I want to run a grounding strap from the panel to the rod outside and figure out what rod to use.

    Once again, the connection to Planet Earth has nothing to do with day-to-day AC power quality. It is there for safety during thunderstorms and other high voltage problem events. Do whatever makes the electrician and the inspector happy.

    What are you basing you comments on?

    Sorry it it not true in reality, where power transformers can suffer from leakage to the secondary and equipment is not designed according to ideal rules. We are debating consumer high end equipment, not military specified and certified equipment. And noise is not just hum!

    It is why, for example, some instrumentation research laboratories and facilities specify extremely low resistance ground connections - we do not want to have problems with what your neighbor does in his section.

    Every good engineering book and paper on the subject of AC power.

    With AC power noise, interference, leakage, lost Neutral and Ground currents have no interest in Planet Earth. They are only interested in getting back to their source which is the power company transformer.
