Jey -
Read all of 430.52. In particular, look at 430.52.C.1, Exception 1. That lets you go to the next size up cb, which in your case is going to be 15A.
hello Jey,
I agree with Cold Fushion, but please also pay attention to the minimum conductor size of 14AWG. Also check conductor rating > CB rating > continous load rating. If you choose too small conductor size, the conductor under certain circumstances can melt before the 15A CB can trip.
