Sparky,
That's about it! The seu cable for the 100 amp service was sided over when the outside was redone at some point. It comes down through a conduit sleeve into the Meter pan. The second conduit is romex sleeved in conduit and sill-plated at both ends from panelboard up to A/C unit.
Several years ago, I came across a house where the SEU cable passed through a soffit on it's way down to the meterpan - or, that's what it did when I saw it. When going up in the attic I found the remnants of something that told me that the previous owner (a Utility Employee) had tapped into the service drop as it passed through the soffit. What I saw was a piece of SE cable coming into the attic and Soldered or Welded onto two Fuses Hanging open in mid air! the load side went down to the location of his electric stove. I think about going back there just to take a picture of it, maybe someday...
