If I was installing a new circuit I'd definitely go with the 10/3,
reason being that the trend these days is for more and more equipment
to have electronics, CPUs, etc. and while manufacturers _could_ design
the power supplies for these items to run from 240, it would be
cheaper for them to use the more common 120V power supplies. Plus,
with 120 at the equipment, you have more flexibility in adding work
lights, accessories (power feeder maybe?) and using 120V coils in
mag switches, etc.
That said, I must say that almost all of my stuff is used and
personally I don't foresee getting any of that "new fangloed"
equipment in my lifetime.
Just curious, though, does the Sawstop saw require 240V with neutral?
For every complicated, difficult problem, there is a simple, easy
solution that does not work.
