Grounding electrode rods

Why is there a distance requirement between ground rods

Minimum of 6’. Spacing them farther apart may improve their efficiency.

This is exactly why I love this board! post a question, get some real good information. Sometimes more than you want, and certainly sometimes need, but always people willing to share their knowledge and expertise.


Each rod has a sphere of influence that aids in displacement and overlapping influences reduces the effectiveness. Six feet is the code (NEC) minimums but separation of 8’ on an 8’ rod is preferred…just not required.

As for the 6’ history, it was a common communication industry length back many years ago and it stuck.

Yes, and “beam” me up Scotty! Sorry Paul just messing with you a bit.


Thanks Paul!

Juan your website continues to evolve nicely. Good job…


Thanks! It’s producing calls everyday which was way beyond my dreams and goals when I started this business just over a year ago.

You’ve worked hard on improving it and those are the results. Good for you.
