Depends where the home is. Since you don't say, we can't help. If, on the outside chance you are in the USA, it would be the NEC. Tell me where you live and I'll tell you what NEC means.

In general, Circuit Breakers protect the wire. So if a certain size of wire is used, the maximum CB size is dictated by the capacity of that wire.
