I think you are outside your area of expertise, and should take this question to the electrician who is working with you on the project.
I answered your other question because it was a simple matter of citing a code article. This question is into the design of electrical systems. We are not allowed, by forum rules, to assist a person with such tasks, if the person is not employed in the electrical industry. Being a design/build professional is not enough of a credential for us to assist you with electrical design. By the way, your question does not include enough information for anyone to give you an answer. But your electrican will know what other information is needed.
With that, I am closing this thread, in accordance with forum rules.
