Thus, you size the wire to suit the load and you size the fuse/breaker to protect the wiring.

Daniel, a breaker is there to protect load and the wiring. If you use 12ga wire instead of 14ga with a 30a breaker you are actually adding a level of security. The wire will be much less likely to be damaged if you have a load that trips the breaker.
