inexpensive long-term stay in Sonora?
I'm thinking of going to Mexico this winter rather than the US as I'm getting dangerously close to spending enough time in the US as to have to file income tax there. :E Going to Mexico is really i...

I'm very aware of the NEC's requirements for ground rods; the value is 25 ohms or less for a single rod or multiples of rods. As you bond additional rods together you are creating parallel circuits and OHMS Law for resistances in parallel apply. And the 25 ohms is still the goal (and I might add that the just released 2014 version didn’t change any of this). If you can’t meet the resistance requirement, you either change locations or go back to the drawing board. In Saudi we used to either drive them in the water or dump water on the rod site.I've also used the water trick in Mexico, but in both places when you are adding water, you have to check your readings frequently.
I just didn't think we needed to get that deep into it. I also didn’t go into how you determine the size (diameter) requirements of the rod.
I've had to create ground planes in the middle of the Saudi desert about once a month when we were moving the Saudi's high speed coastal patrol boat squadron from place to place so I’m very familiar with driving multiple rods (and pulling them back up). You may have tested the ground rod connections but I have not only designed, but supervised the installation of whole electrical and communications systems, including the ground plane.
I agree that proper grounding and bonding is critical to ensure electrical safety.
I wasn’t aware of the Soares book. Thanks, I’ll have to check it out and maybe add it to my library.
