Electrical Questions? Ask an Electrician Online.
Hello, you are asking a lot more than a single question here, but for electrical engineering or design services. The total load calculations required by the electric utility will require the project electrical engineering, the total load numbers will not be accepted without that.
If you supply a scaled drawing of the site and location of all utilities showing distances of the runs, and allow me two or threed days to do the calculations and produce the needed conceptual diagrams you might be able to take that to the local building inspection authority and get a permit. That will be a two day additional service charge if you are interested.
Otherwise you need to talk to an electrical engineering firm (Cost $3000 range) or work with a licensed electrical contractor who can do the design as part of his job, and pull the needed permit.
Let me know your preference, we can go from there.
