S'all good Mr Jet. Thought of you when I was in Portland. I'm looking at the power lines feeding all of the houses along our daughter's street. Lot of em. Then I realize they're all entrance cables coming from one pole going to 6 homes. Looking closer, I follow the feed to a distant pole with a tranformer. Look up and I can see the single primary up above the rats nest maze of wires below it, but no dedicated ground to the transformer, like there is on every rural system I've ever seen. Neighbors must have thought I was nuts (not far off) squirreling all around the poles trying to find a ground. I didn't. So, does this system get it's grounding from all of the homes it feeds (I can see their ground cables) or did I just miss the main ground?
Should be a neutral wire that carries the ground. All of our equipment poles have downgrounds on them as well as all new poles we install. Should be 3 wires coming down the front of the pot the middle wire is the neutral. We have to be careful working out of town because their open wire bus can be different from ours. Our neutral is always in the middle on open wire. Of course triplex its always the bare wire. Does that help? Imagine climbing over all the phone and cable stuff on a lotline just to work on that rats nest. Plus you have to be fall arrested the whole time. Can be interesting.
