I'm installing two 5/8 inch grounding rods six feet apart. The first one is in place. After trying everything to get the second rod in, I just couldn't get beyond 6 feet. Worse yet, I couldn't get it out.
Would two six foot grounding rods (right next to each other) be the equivilant of one eight foot rod? In other words, I'm thinking that I'll cut about two feet off the rod that's stuck, then put another 8 foot rod next to it. Assuming I can only go 6 feet with that one, I'd probably end up cutting two feet off that one two. Due to landscaping bushes and trees and an AC unit near by, I can't take advantage of the 45 degree angle idea. Also, I'm pretty limited in where I can put the rod and still be at least 6 feet away from the first rod (which was put in successfully).
What is the reasoning behind keeping grounding rods at least 6 feet apart?
