All:
I've read the service life of copper-clad ground rods can last as much
as 40 years depending on the type of soil they're in.
Be that as it may, I found some corrosion on 4 copper-clad ground rods
that are bonded to the tower and they've only been in the ground for 15
years. The corrosion is light at a foot below grade, but I suspect it
could be worse down the length of the rod.
Replacing the rods isn't costly and it's worth knowing the grounds are
in good shape. The question is what to do with the existing rods?
Is there any benefit in placing the new rods near the old and bonding
them even though the spacing is close?
Tony
