Ground rod Clamps

Is this all one service ? The rods must be min. 6' apart 250.56 and bonded together. Also, this type of clamp I use for interior applications bonding piping is it rated for direct burial ? And I do not like the way they ran the GEC in the clamp... IMO
 
Notice how the wire loops up and over the ground rod.

This is a new concept called "inductive grounding" :)

LOL
its a 5/8" clamp & a 1/2" rod.
They had no clue, they could reverse the clamp, I think they did this to keep the clamp tight?

OH yea, they ran 2 #8awg, exposed outside into the exterior wall then into a 4" round box, then into 3/8" flex, then to each panel. I missed the picture of that.

It had to be the yard guys doing the work.

Go figure!

picture this... two, 6 circuit panels. Buyers inspection report asked the panels be grounded. there is two ground rods a foot apart, both with the clamps installed like this. Each one has its own ground rod.

No, its a residential realestate buyers inspector, its for information & negotiation only, they never reinspect. I just fixed it for the owner when I raised the service entrance with a new mast.
 
I wonder if those are the special #2 ground rods, or maybe the #4 size.

For those not familiar with the #2 or #4 ground rod, let me introduce you to the standard, every day usage ground rod--#8.

I think you get the idea :lol:
 
I just read a installation manual yesterday (I won't name the company to prevent embarassing the guilty party) but it said a additonal ground rod was required at their equipment location (a fan) to "ensure long life and correct working of the solid state control electronics."

To make matters worse, their suggested method of installation was to "dig a hole large enough to hold 1-2 gallons of water. Pour water into the hole, and work the ground rod up and down (with bare hands). The water will loosen the soil up and allow you to push the rod 8' into the ground".

Apparently, everyone on this forum has been driving ground rods the hard way :D

Talk about not having a clue.

They also said that adding the water makes a better ground connection :?:

I'm not an electrician, and I don't have any first hand expierence driving ground rods. So please tell me my intuition is correct and you can't just push a ground rod 8' into the ground even if you did use 2 gallons of WD-40 :D

Sometimes you can! If you can get to a building/house that was just backfilled, sometimes you can push the #8 rod all the way in.
Most times you will need to use a sledge hammer or electric hammer (drill).
 
I was kidding about WD-40... I use a slide hammer.....You did not take Me serious did ya? And I can push a rod about 4' in the newly backfilled area.
 
Yea, I knew you were kidding. It would take a lot of those little spray cans to fill a hole with 2 gallons of WD-40 :D And these instructions wern't talking about somewhere backfilled. They make it sound like you can just push it into some solid Illinois clay. (Some places around here has bedrock at about 4' down. It would really take a while for that water to loosen up bedrock.)
