So here's another Q:

Is a 3-wire bx cable leaving a panel *necessarily* an edison-type deal? Do
the two hots *always* have to be connected to separate phases? I would
think so, but I'm not absolutely sure. But I am going to put them on sep
phases regardless.

From the cable alone, "not necessarily" -- it _could_ be a 240V w/ third
conductor ground. Of course, it would still require the hots be on
opposite buses or there would be no potential between them and, of
course, the third conductor wouldn't be neutral but ground.

But, if'en this-here supposed cable is serving 110V circuits, then yes.
(Or at least at the moment I can't think of any alternative that would
be Code-compliant).
