[RFI] w7ekb & ground rods

[Donald W. Kane via RFI]

The NEC does not preclude galvanized ground electrodes.  Article  250.52 
(A)(5) indicates what is permitted by the NEC....it includes galvanized  pipe 
and rod electrodes. Note: Some local codes will prohibit galvanized  
electrodes due to soil chemistry which will attack the zinc coating. There are  UL 
Listed ground rods available from some suppliers.

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.
