You can always use a smaller feed breaker and even obtain a smaller main breaker if you want. But a higher rate panel should cost under $100 more if you're already doing the work. Replacing it later with a bigger one is more heartache. | |

I think the breaker in sub panel must equal or be larger, so feeding a 200 amp breaker/panel from a 40 amp breaker is good(if you wanted). The sub panel's breaker basically becomes a disconnect use. Usually it is recommended to go big(200 amps) for sub panels, even if never expected to use that much. | |
