Maybe I'm grasping at straws here now but I want to clarify something here. Not being a professional electrician I may have used the wrong description of my situation. I was wondering why something that was likely run in 2005 would be so shortsighted as to not include what at that time would be called best practice or at the very least code.
Let me try to explain in a little more detail. The wires run to the post are three 4ga wires, two hots, and one common, no fourth bare or ground wire. But, here's what MIGHT make a difference in all this, maybe not. The run is not connected to what I might consider the "Main Panel" but is run from two 60 amp paired breakers in the box containing the power company's meter. This box contains a main shut off for the house (manufactured home), the RV run, a workshop run, and breakers for some run I've yet to identify (likely for a well pump they never put in). As I said this may or may not change things for those in the know.
