You're supposed to size the wire for the current and the length of the run
so that the voltage drop at max load is allowable. If you do that then saw
should not be "bogging" due to voltage drop in the wiring under heavy load.

Consume more power? The first guy to respond to the question was spot
on. Has everybody who attemps to reply actually run a bunch of tool on
both 120 and 240? Same tools? Tried both ways? If you use a gawdawful
heavy cord direct from the service panel, maybe you couldn't tell the
diffence. In the real world, with similar gauge wiring, you'll find the
saw will start quicker and bog less. Since it bogs less, it runs
cooler. IMHO


In the real world if you're using the same gage wiring for a 240 volt
circuit and a 120 volt circuit that has to carry twice the current then
it's time to sue the electrician.

Why would the saw run cooler if there is more voltage to the saw?

To first order, won't the saw consume the same amount of power when
using 120V or 240V (assuming of course the motor is wired correctly for
the
appropriate voltage)? That said, in reality I think that saw will
consume a little more power (maybe 5-10% more for a typical
installation) in the 240V configuration than it would in the 120V
configuration.

By doubling the voltage, the current is halved. Therefore the I/R
(voltage drop of the wire, which is a function of the current and
resistance in

wire)


is cut in half. (more voltage to the saw).
The saw starts better (the most current is on startup) runs better,
cooler

and


should last longer.

Does changing the voltage capability on my TS allow me to work the saw
harder or does it simply help prevent overheating and burnout and a
few breaker runs?

I have already blown out a capacitor on the motor, ugh. (120volt

setting)
