Oh, and UKCat, it isn’t “less power draw” when using 220v current. Power (total wattage) is the same. It’s just that you are doubling your voltage to the machine while cutting the amperage in half.

For this reason, you can run more machines on a given 220v circuit. Running a TS at 6.5 amps instead of 13 amps on a 30 amp breaker (standard with 220v) provides a lot of overhead for other things. So, with 220v, you won’t have to dedicate a lot of 220v circuits to your tools UNLESS you run a lot of 220v motors simultaneously. That’s not the standard MO for a home shop.

Cost of the wiring for 220v yourself (not with electricians) is typically cheaper because the two legs can be run on thinner gauge wire as compared to 110v.
