What size breaker do I need?

I've wired everything I need to in my addition I have a subpanel mounted and all wires running to it. The most I have on one circuit is 4 outlets. All wired with 12/2 what size breakers do I need to install in the panel?

Article 240.4(D) of the National Electrical Code requires that a #12 be protected by a breaker no larger than 20 amps. You could use a 15 amp, but there is no really good reason for doing that. You can’t use a 30 amp. So I’d go with 20.
