its a 3/4 hp 3 phase. Its on a 15a i think. So it should be enough luckily. Now the wiring is where i am stuck on due to school. Looking for a good source on how to wire it. If you have an idea of which site or video gives me a close diagram that would awesome.Just be aware that the current at the wall needs to be twice as much at 115 vs. 230 VAC input. So for the most part you are limited to ~ 1Hp on a 15A circuit and 1.5Hp on a 20A circuit. Breaker wiring is not designed to be run at more than 80% of the breaker size, and there are other wiring/breaker requirements for VFD's. In this application, a 1 Hp VFD with a voltage doubler which outputs 3 phase at 230VAC are available through multiple VFD manufacturers.
