I made a converter using a static and added a 5hp motor and magnetic starter so if there's a voltage outage it will shut down till restarted. It runs everything in my home shop. I think the biggest motor is on the Powermatic band saw 3hp. It's probably not working to it's ability because it does get a little hot when using for a longer time. The others are just 1.5hp on the Delta Unisaw and shaper. But like PUGS said; You're only running one machine at a time and that won't overload say, a 5hp like mine. One time I bought a hyd punch and it seemed a bit lacking of power. It was hard to see but when I cracked the motor cover open I saw the problem-440V
Changed the wires around to 208v and it works beautifully.
