Are you saying that I was in error using 10/2 for my 240V water
I don't think so. There is no requirement to use xx/3 wire for 240V if
a neutral isn't called for (as it is with ranges and dryers since the
'90s). Your table saw or planer circuit could just as correctly be run
with xx/2 cable.
The NEC makes a provision for using the white conductor in NMC (Romex)
as a hot lead for just that circumstance (and also for switching)::
you must mark the white wire at each end as a "hot" conductor. A piece
of tape will do, although I used a red magic marker coloring each
white conductor in all my 240V shop circuits--I could just as easily
have colored them black, as there's no "polarity" marking requirement,
