It can be found in the transformer manufacturer's manual for the equipment.

Sorry, not without a purchase order and much more information. If I am going to be doing your job for you I expect to be payed.

If you are having a problem try looking at the technical documentation available or try a consultant (the answer is based on simple electrical theory coupled with set requirements listed in local electrical standards and regulations, all of which you should know if you are performing this design).

Why make life difficult. Get some electrical consultants to do the job.
