Everything you do properly to reduce the chance of common mode noise being conducted into the house will also reduce RF feedback, power line fault damage, and lightning damage risks. Even if it makes

That's one reason why I like to augment a NEC-required mechanical connection with silver-solder. The mechanical connection will degrade with time but it will take significantly longer for a silver-so

I have driven copper ground rods in about ten years ago, then wrapped a couple turns of #4 wire around the top and soldered that to the rod using plumbers solder. These connections are as good today

I seem to recall that one of the arguments against soldering ground rod attachments was that a lightning strike would first evaporate the solder and then burn the connection. This would create a peri

It would really be something if in-the-slab copper was floating electrically. I have seen the copper connected with a heavy wire out of the slab connected to the ground bus in the main electrical pan

No, that should be done at a central point in each premises, and only when the plumbing is metallic and conductive to the earth. 73, Jim On Fri,10/30/2015 9:58 AM, Dan Edward Dba East edwards wrote:
