1.1 Product Overview and Scope of Ground Rods

Now before we get to far a point I must raise if you tell the guys your going drive ground rods with this they may frown and not rent it. So get a bit any bit tell them your bust block wall with it.

Now you have the jackhammer what you need is to place the ground clam loosely over the ground rod so it will slide to bottom easily. Place jack hammer over the ground rod and drive it home. This method works in rock soil darned near any place. It is fast simple. And cost around $20.00 to rent the hammer all day. Best part is no sweat no bumps or bruises. And you'll have the rod down faster then our beer. Not that I would dare think a ham would drink beer during work oh no. Well again as always folks I like to thanks you and the great staff of eham for permitting me to do this littlie how to thing. God bless and good dx. Jeff/N3JBH

"Twenty years in the electrical trade and I've put a hammer to a ground rod maybe 10 times."

About the same for me, but have never heard the "water in the hole" trick. The ground here ranges from sand, which is real easy to work, to rock filled clay which is a real SOB. I have spent over a half hour with a sledge hammer trying to get a ground rod in what seemed to me like concrete. Hitting a 1 foot or better diameter field stone can be a real joy, too. I will gladly try anything to make the process better, like "water in the hole". The electric hammers are not popular around here because the field stone laden soil is just too much for them. I know that nothing will make driving stone easier, but I can see where it would work in clay full of smaller sized rocks, allowing them to move out of the way.

It's stuff like ground rods that make me appreciate our apprenti. (Latin, plural of apprentice)

Also, I would think that if there were a question of conductivity, this would be a good time to put something in the water to help things a little. I am not sure of salt, but fertilizer may not be a bad idea.

Now, kind of off, but still on topic...has anyone had to try to remove a ground rod?

It can be done, sometimes as easy as using a pair of vise grips and twisting the rod out, to hard enough to use a slide hammer modified to do ground rod, or a fence post jack which also has to be modified.

I have had bad luck leaving the ground clamp on. It always seems to get buried in the dirt. We usually just file or grind the peen off the end. Cutting the end of the rod is a bad idea as it may make the rod too short to be legal.

I wonder if there could be a way to make this fun, like designing a ram set device in which we would load a 3 1/2 magnum 12 guage shell into a tool and fire the rod into the ground like a bunker buster? The real sharpshooters could try to shoot the rod through the clamp as it lie on the ground, electrode conductor intact.

I like the idea...I'm off the the drawing board...hello Paslode?

1.3 Ground Rods Segment by Application

In stations, , and other installations where signal quality is critical, a special signal ground known as a "technical ground" (or "technical earth", "special earth", and "audio earth") is often installed, to prevent . This is basically the same thing as an AC power ground, but no general appliance ground wires are allowed any connection to it, as they may carry electrical interference. For example, only audio equipment is connected to the technical ground in a recording studio. In most cases, the studio's metal equipment racks are all joined together with heavy copper cables (or flattened copper tubing or ) and similar connections are made to the technical ground. Great care is taken that no general chassis grounded appliances are placed on the racks, as a single AC ground connection to the technical ground will destroy its effectiveness. For particularly demanding applications, the main technical ground may consist of a heavy copper pipe, if necessary fitted by drilling through several concrete floors, such that all technical grounds may be connected by the shortest possible path to a grounding rod in the basement.
