Audiophile-grade ground rod?


Anyone know of a high quality (purity) copper home grounding rod?

Replacing my old rusty one will be significant, but wondering if there are brands that are higher quality than others.
thanks

The ground rod is for over voltage from anywhere other than your home.
Lightning, transformers, surges, but your home? You don't need it to complete the circuit, but you need it to have self protection, quicker protection, safer protection. Unless your home is prone to lightning strikes, use lightning rods, like in the movie "Powder".

Lightning strikes or recurring surges really suck.

Solar power isolation? I'm getting ready to install solar, this should be fun.. I'm thinking a solar trailer, or solar storage sheds with solar on top, and onboard batteries. Easier to maintain vs crawling on a 8 &12 pitch roof..

@jea48, thanks for the detailed explanation. I didn’t consider the amount of resistance would change with the grounding rod(s) + cable added.

If you watched the Michael Fremer video, he went all-in with his grounding scheme.

Yes, I did watch the video. It was pretty interesting to watch.

I don’t think I’ve ever seen Cadwelds (Trade Name) used in residential for connecting the ground wire to the ground rod. That welded connection is forever.

One thing for sure Fremer was ready for a new electrical service. Did he say how old the house was?
