I am specifically talking about surges generated out on the power
lines on the poles propogating into my home. I realize that nothing
can stop a direct lighning hit. I have three ground rods spaced at
10ft apart joined at the center one with 6ga bare copper. I have read
not to create a ground loop by having different ground locations, so
besides what the builder had done with a piece of rebar embedded in
the concrete and one ground rod, I added three more. The 6ga run to
the meter and the load center behind it is about a 6 foot run.

I next have to find a surge supressor for the cable coming into the
house. I opened the box mounted on the outside wall near the power
entry and there is just a grouning block in there. Nothing good to
say about the cable installation.


Were those ground rods tested for ground resistance? How deep are
they, and what part of the state are you in? There are a lot of
different soil conditions in different parts of Florida. We had to have
85 feet of ground rod driven before we passed the test in northern Lake
County about 20 years ago. It was about three feet short of length of
the well pipe.

Fortunately in the UK, the power company supplies the ground connection. That
saves a lot of such bother.
