Does this have anything to do with a pool?
My boss got a call Friday from someone sounding desperate, had a home inspector requiring a pool grounding grid to be tested (old pool) probably $1M home, we have gotten these calls before.
Apparently is a law in some states for pools.
It was holding up a home sale.
He asked I had herd of that and the only place I have is at Mikes classes, I have never tested ground electrode systems of any kind and would not even know where to begin,
I asked around at the supply house and people I know and I dont know any electricians here that have tested a ground rod or any other grounding systems to see if it worked nor even have such a tester.
I told my boss to pass on the pool job because of the liability, He was going to test it with his regular multi meter and write a letter, but then wanted me to.
