Although, because its located on the other side of an adjoining house, and it was pitch black except for his head gear's super bright LED flashlight, I didn't catch up with him until after he had been in my meter box. I failed  to ask him at that moment if he found my meter's terminals loose. All I know is that he's already checked them, and could have racheted them before I got there, but didn't feel it necessary to comment to me that anything was loose.

That, ironically, is KCP&L's top threshold  for voltage on any one leg. I remember him asking me if we've had a spat of burnt out light bulbs, and told him in four years, we really haven't had many burnt out bulbs… certainly nothing out of the ordinary. The other phase was within his tolerances.

At any rate, while next walking to their pedestal, I remember commenting on how important a ground (As well as a common) is in an X10 system, which he wanted to object to since "common is the same as ground" as he tried to tell me. Imagine my joy, after it took him 20 minutes to even open the pedestal, that we discovered that my grounding wire was totally loose in the pedestal and in no way connected to our home's electrical system. The only "ground" I had was the common.

Ahha! This provides confirmation to my comment about the neutral/ground 
(they are bonded together at the panel in older panels) being important 
to balancing and equalizing the voltage. I can imagine how you felt as 
to your take on isolating an issue that was with the utility company 
part. Obviously you had covered all other bases. I also would assume 
that just as SOP the lineman would have tightened those meter lugs while 
he was there. However the emphasis is with that assume word<g>.

Well… he admitted that was strange, and that he's only seen that phenomomana twice before in his 20 years, and concluded that the only thing he could think of was that there must be a lot of iron in our soil... that in effect, was acting like a transformer in itself.
George,
My mind wonders if a change in frequency (dropped) isn't causing the 
small voltage boost from the transformer. Sorry to dwell on this 
frequency thing but something still doesn't seem right here. If voltage 
is increasing from the transformer to your panel that flys in the 
opposite direction of what typically happens. Voltage (depending on 
distance and wire gauge) usually drops slightly. An increase is 
definitely _not_ normal. I would ask that the power company look into 
this as what they are delivering to your panel isn't right even if it 
meets their specs.

You may have also seen what I wrote James regarding my four AC tests. The simple fact is that I need many weeks of observation to really get a correct "warm and fuzzy" feeling about where I really stand now.

>> George, The lineman had no authority beyond the power company side. That is pretty standard policy except maybe in new construction. Good that your buddies are tightening the main lugs as they are yours. However, there are other possible trouble spots at the meter box. In most jurisdictions that box is the responsibility of the utility company and usually has their seal on it. In my time I've cut off a few but know that was a no-no except under certain conditions. The terminations in the meter box need checking.(imho)

That ground actually is needed to balance the single phase of 230 VAC we all buy as it is the center tap of a drop down transformer. (4160? to 230 VAC) Your ground was actually acting as the Neutral (or center tap) via what is sometimes called the phantom system (ground being common) The power company bore responsibility for this end of the incoming service and the loose terminals is an illustration of my comments concerning terminating aluminum wire. (expansion and contraction) Did they also check at your panel lugs on your Main breaker as a courtesy?
