Horrible idea

Horrible idea

This is a horrible idea, is this a remodel/refit, or a new service? What's preventing you from getting 200 amp service from your electric company? I don't think that this would ever pass an inspection anywhere.

Can I use a panel with a 200 amp main breaker for a 100 amp residential service. I need the larger number of breakers available with the 200 amp panel. I can't find anything in the code that says I can't.

How would the 200 amp breaker protect the 100 amp service conductors?

Read 110.9 and 240.4

Get yourself a 200 amp main lug panel with the number of circuits needed and then install a 100 amp main breaker kit. Make sure the panel you buy will accept the kit.
 
You could install a 100 amp meter/disconnect outside, then feed the 200 amp panel, as long as the wire size was correct for the lug size in the panel. In the end, this isn't any different then installing a 100 amp panel, with a sub panel.
 
If the 200 amp main is the service disconnect and the service conductors are not at least 200 amp conductors, including allowed conductors from 310.15(B)(7), then the answer is no. If this 200 amp main is supplied by conductors protected elsewhere at or below their ampacity then the answer is yes.
