While we do appreciate your joining us in the Forum, I would have to agree with texie.
If you need us to provide you with that answer, it opens up a whole area of possible pitfalls with a transformer install including overcurrrent protection and grounding.
If you would like to provide particulars on your proposed design I'm sure there are folks here that will critique it for you, but I don't feel it proper to supply a "how to" answer.
I am closing this thread, but encourage you to repost once you have addressed the install yourself.
