Bonding help
Hello to all and thanks for any help you can provide me.
Some time back I looked into installing a wifi antenna on the outside of my brick office building here in town. I would offer free wifi to the immediate area, shops, coffee houses, etc. and perhaps get some free advertising out of it. When I investigated the installation of such an antenna I was stopped in my tracks because of the bonding (grounding) requirements. The need to install #6 copper wire from the antenna to the building ground on a direct external-to-the building path was something I was not prepared for. Yesterday, the lottery agency had a defent size (bigger than home size) satellite dish installed on the roof of our building. There is a small store upstairs from me and this will replace the phone connection they had been using all these years. As I look at the installation from the ground I can see what looks to be the coax wire and a greenish wire leading from the dish mast to the base of a vent pipe that has been on the roof. They lead in together at that point. The store is below. The roof is an A-frame and made of wood as is the entire building more or less. Question: Is this to code? I do not believe it is since the ground wire, if that's what it is, leads inside the building somewhere and not externally to the main ground. If hit by lightning it would direct the energy into the building which is wrong. Second, it leads away from the building bonding point, which is down on my ground level in the electrical room at one end of the building. My hunch is it has been connected to a water pipe or electical conduit in the ceiling or wall. I'd like to call the town electrical inspector but I want to make sure I am correct in this. The theory of bonding at least and the need for an external lead to building bonding point. Recently, a building was hit by lightning in town and the damage went from the roof down three floors and was very extensive. Can anyone advise me on this? |
