To continue what Rich said, around here we pay for electrical power by the
kilowatt-hour. Wattage = voltage * amps. So if your tablesaw draws 15 amps
at 120v (15A * 120V = 1800W), it's the same as 7.5A @ 240V (7.5A * 240V =
1800W) in terms of actual power used, and therefore cost.

BTW, when replying to (and quoting) someone else's post, it's poor practice
to include the same quote identifier in front of your text. Makes it hard
to pick out what you're trying to say. This is simply my opinion, unlike
some people who will try to what an "Internet Standard" is (regarding
top/bottom posting).

AFAIK, there is no energy savings to be had, running 220(240?) instead of
110/120. There may be less voltage drop when running 220, but no energy
savings.

DAGS for "120v 240v difference", and have fun.

It probably depends on how much you use it. I inherited my dads wood
working equipment, and most of it is 220v but, he used it a good
portion of every day, so it made sense to have it on 220v for the
savings on electricity. I will say they are more powerful than before
he made the motor switch, you just can't lug down the belt sander, and
the table saw is like a hot knife through butter. I don't know if he
upped the HP when he made the change, but they are sweet machines now.


Running 220 volts cuts the amperage in half.This is an energy and money
saver.
