Not famous in these parts, never heard of the "AOC". :smile:

I have done Federal projects and had to deal with GSA inspectors who where entirely clueless when it came to the work they where assigned to oversee.

I could see the GSA misinterpreting the 25 ohm rule.
 
Some of you have argued against some of the merits of ground rods, and I don't mean to dispute any of your information. :smile:

The question was asked; why do we use ground rods?

Most GEC's I see = min 2/0 copper.
GEC for ground rod = #6. :cool:

As far as installation is concerned you already have the tools, men, and materials on site for the trans pad. Drive 2 extra next to the building and your covered.

lucky for us one of our farm boys who was strong and had deadly accuracy - I think we had in 21 before we got it

If he was a farm boy he should have known about T-post drivers. ;) A heavy one of those will drive a rod very well, as well as doing a good job of increasing the thickness of your callouses.
 
Not sure about that, that dirt was hard, during a drought too. the funny thing was after about 10 we wereall tired and using a 72 when we got it down to sitting level and took a reading and viola we yelled for the inspector and said look look and he was amazed , he was joking "you must have hit a water pipe " he said and sighned off , he waqlked away and then we noticed we had leaft the drill sitting on the top of the rod 60 ft. away - Pepco sure has a good grnd.!! we had to be honest and bring him back over and start again :rolleyes:
 
I am doing a job now and have a water and footer ground, I had no intention of driving ground rods, " I actually drove the rods in then I was thinking I didn't need them since I supplemented the water with a CEE" so the rods are in the ground but I don't plan on running my #6 unless I am wrong.

Now that you have installed grounds rods they are present and should be included in the grounding electrode system

If in the desert, you may have a hard time getting to 25 ohms and might want to consider an ufer ground as part of your grounding electrode system.

Rebar in building foundations or footings meeting the criteria of Article 250 may serve this purpose. But these must be bonded to all other grounding electrodes.

DOH!, that is true.

He did not need to pound them in the ground but now that he has he must use them.

Maybe they are in to deep and got 'lost'. ;)
