[RFI] w7ekb & ground rods

[dalej]

The copper coated rods eventually will deteriorate, I've found too.  After pulling them out I've found them speckled where the copper has eroded away and the base material shown.  I like the solid copper tubing as ground rods better, but they are not that easy to embed.  Use water to get them in the ground.

Frank,

You might know this since you have some tall towers up in the air.

Did the contradictions between NEC (copper ground rods) and EIA/TIA-222F (12.2.2-galvanized steel ground rods) ever get resolved?  At work we follow NEC on comm buildings and are forced to follow 222 on tower structures.

The only place we’ve actually used some new galvanized steel ground rods was on guy wire grounds on our 500 ft towers and only in the southeast part of Nebraska with the known soil problems for galvanic corrosion.  That was after an inspection we found 1.5 to 2 inch holes on 4 inch anchors and the copper rods almost totally gone.

NEC quotes relevant to this discussion:

Not less than two driven ground rods placed at a minimum of 6 feet
apart when a non-metallic water piping system exists or is to be installed.

A separate grounding conductor to each ground rod shall be utilized

The grounding electrode conductor shall be solid or stranded, sized in
accordance with the requirements of the NEC but shall in no case be less
than No. 6 AWG copper or No. 4 AWG aluminum or copper-clad aluminum.

All ground rods will be required to be minimum 1/2" x 8' copper weld or
5/8” x 8’ copper plated only.

No galvanized rods or piping will be accepted as a grounding electrode.
