    It's bare, and runs alongside the coax in the same PVC conduit. It was done that way years ago by whoever sold DOT the systems. These are highway advisory radios.

    I'll tell them that is what is needed. Thanks for the suggestion. I think you talked about this in the QRZ.COM articles, it sounds familiar.

      Won't be a good ground. For a rebar to be a good ground, it's got to be a 20' length, no way to know poking around if it's a long piece, or a short stub, that won't perform.

        Nothing wrong as long as you use a dedicated and properly sized ground wire.

        What Sunking was referring to was that if the conduit installed underground was rigid galvanized steel conduit then you are allowed to use "it" as the ground path instead of the ground wire.

          Won't work, there is about 25 feet of concrete I need to go under with some pool piping in the way, plus I still need to cut just to get under it. Can I just run armored bonding wire along the house wall and not below ground?

            Yes Sir. By code it works, just not best practice to run in PVC. The more copper in contact with dirt, the lower the impedance.

              Hi,
              So I read through quite a bit of this thread, (though I admit not all) I am trying to determine if I need to run 3 wires from my solar panel combiner box at the array to the house, or just two. From what I am gathering in the earlier part of the thread is that it needs to be 3. Later it gets a little confusing. Especially when the topic of electric fencing, towers, etc all get brought up. I have electric fencing. I also am putting up a tilt up wind generator tower with guide cables 4 ways. It is a 3phase AC axial flux unit. I was told to ground the tower at the base, and bond each set of guide cables together to 4 separate ground rods at the cables anchor points. My solar is going to be near my tower area as well. The location of the tower and array are 400plus feet from the house. So 3 wires (one for bonded ground) or just two that 400plus feet? If I do need the bonded ground wire that can be smaller can't it, and just be a bare wire in the same conduit with the two PV panel wires? On a different note can the wires from combiner box to house through plastic conduit be THHN, or is USE-2 wire required?
