I have 415 amps worth of branch circuit breakers. what size service do i need for my house? is 200 sufficient

Contractor's Assistant: How old is the system in question? And have you consulted an electrician yet?

It will be new construction.

Contractor's Assistant: Do you plan on doing the work yourself?

Yes. I am an electrician, but not sure of residential codes as I am an industrial wireman

Contractor's Assistant: Anything else we should know to help you best?

The house is existing and we are doubling the square footage and adding a garage. I am going to re pull all existing electrical, and rough all new construction
