This message is from: Lori Puster <[EMAIL PROTECTED]> The best indicator of minimum rod depth: how far down you have to dig in the Summer to find moist earth? If you are not sure, use a shovel or post hole digger to find out. Grounding rods should be sunk at least 3 feet past that depth.
I find 10 foot rebar posts work well and they are fairly available and cheap. Their only problem--they are initially too tall to drive with a mallet unless you stand on a ladder (or play basketball for a living). Two, or even three posts spaced 10 feet apart will provide the most reliable system. Make sure your grounding wire is securely CLAMPED to the rod(s)--not just wrapped around. Wires connecting multiple rods can of course be uninsulated *and* along with the rods themselves, buried in the ground to keep horses/people/pets from tripping over them. When using rods other than copper or aluminum, check them every year for rust. Replace any that are broken through or are so covered in rust "flake" that they no longer work well as electrical conductors. Lori P MoonWise Farm Veneta OR
