Did you mean to say that the indoor panel will be 200 amps? If so what panel are you using outside? I have never seen a 200 amp CSED with sub feed lugs that had room for more that 16 breakers. Most of the homes we wire have 400 amps services but when we do use a 200 service we usually install a 100 amp panel inside the house. All of the general lighting, small appliance circuits, etc go in the 100 amps panel and the large loads (A/C, oven, pool, etc) go in the main.
