What kind of comment is that?
I'm sorry, that
was over the line. I apologize, no offense intended.
I just can't understand how you can pick one item out of a list entitled "Electrodes Permitted for Grounding" and decide it's not really a grounding electrode, but a ground rod (which is no unreliable that it is all but required to install two of them when used) is.
Again, sorry.
