One that messes with a lot of electricians is a corner ground on a 3 phase system. They are many out there, if you going to work on 3 phase study up a little on them.
You would need to have three phase brought to the house via transmission lines which would be different and separate from the single phase you already have. Terribly expensive for a residential installation.You and me both... Local electricians won't even call me back about 3phase in residential. I need it in my shop to run a 70 year old 14" tablesaw
Yes they do. You might want to look in the Grainger Catalog for the type you need.Do those things actually work? I need one that will screw in/out big flood light type bulbs.
What are you using the bypass for? All the VFD's I've installed and maintained just used three phase 480v.Lets ratchet this up a little: Your 3 phase feeds a Variable Frequency drive with a bypass...now what do you do?

You can run 3 phase equipment a couple of ways from 230v residential power by using a VFD (variable frequency drive), an inverter, or a rotary phase converter.
It's not that difficult. They have been using single phase to run 3 phase equipment for a long time. Some of it is as simple as three electrolytic capacitors in a bank and manipulating the phases through timing using the capacitor values. The issue is that the equipment can get more expensive exponentially depending on the size of the 3 phase motor your trying to drive. 1-3 hp, can be done for a couple hundred dollars. A 5-10hp would run into the thousands, and so on.I’ll have to crack the books for a few years to get on this level.

There is a great book you can get called "Refrigeration and Air Conditioning Technologies" it has a few electrical chapters that are awesome. The bonus is you can learn a little about the heat/air stuff also.
