    Overall then, and I am probably not going to like the answer here, I will have to run conduit? Coming off a 60-amp breaker, I will be going just a little under 50' to the subpanel, and I am assuming I cannot run a bare ground wire between floor joists and through walls alongside a 3-strand "Romex" of the proper size ...

    Define "3 strand romex". Do you mean "3-wire"? As in black, red, white, ground?

    If it is 3-wire then the ground will be the proper size automatically.
    If it is 2-wire then it was never correct in the first place.

    Now I'm confused....

    I have in the past worked with 4-wire SJ cord wiring 3-phase motors and such, but I do not recall ever seeing 4-wire "romex". So, I was mistakingly thinking about black-white-ground 3-wire cable while assuming I would have to add a ground wire to get a total of four ... and I now realize all of that would incorrectly add up to 2 hots and two grounds.

    NM cable for example, 6-3wG, or 4-3wG is four wire cable.
