I don’t understand why 220v is so important if you aren’t getting something with some hp to truly take advantage of it?

I can think of three reasons to switch a motor from 110v to 220v…

1.) You are running on a typical 15 to 20 amp 110v circuit and you keep tripping the breaker. But if you dedicated a 110v circuit to only the saw, it’s a moot point.

2.) You are experiencing some power loss due to longer wiring runs with the 110 wiring. This extra resistance also causes some excess heat.

3.) You can save some expense with 220v because the legs can be smaller gauge wire than a single 110v line.

Otherwise, there’s no practical advantage to switching a motor from 110v to 220v. 2 hp is still 2 hp.

I thought I always could get by with my direct-drive Craftsman TS…that is until I got the 3hp Unisaw. There are just some cuts that I can’t imagine doing with less. Its certainly a debate, but I don’t like the saw to work anymore than it has to…it’s kinda a safety concern with me…the longer and harder it runs, the more bad things can happen, IMO.
