I do not understand the logic behind the following. A single ground rod is required to have a resistance to the earth of less than 25 ohms. If it is over 25 ohms it must be augmented with an additional rod not less than 6 feet away. And if the resistance of the two rods still exceeds 25 ohms no additional rods are required. Why, if a single rod must be less than 25 ohms, can by adding a second rod make it OK to exceed 25 ohms? The logic would then follow that it doesn't matter what the resistance of the rods are as long as you install two, and if you do why even bother to test the resistance. What am I missing here?
Thanks for any help you can provide.
