[Shop-talk] Table saw, (it's here.)

[Steven Trovato]

Things like electric clothes dryers do this all the time.  The big 
heating coils are 240V, but the light and electronics are 120V.  It 
is easy, IF you ran a neutral when you did the wiring.  Wiring across 
the two "hot" wires gives you the 240, wiring from either one to the 
neutral gives you 120.  Now, there is also a green or bare ground, 
intended for safety only.  It used to be that appliances would 
"cheat" and use this as if it was the neutral line for minor loads 
when there was no neutral line present.  This isn't allowed 
anymore.  That's why new dryer outlets are 4 wire, and old ones are 3 
wire.  So the big question is, did you run a neutral line?

Now, for the disclaimer.  Nothing seems to generate more hostility 
than internet discussions on electrical work.  I am not an 
electrician.  I have not looked up the latest code, or anything 
specific to table saw wiring.
