In this video I build/rebuild a 30HP phase converter.
I found this phase converter on craigslist. It had some blown capacitors and other issues but the motor was in great condition and most of the other parts were there. I picked up a capacitor tester and tore the entire thing apart to rebuild from the ground up. Here is the video of me doing just that.
30HP is way more than I need but I was able to get the parts really cheap.
