Correct Breaker Rating?

This afternoon I was in the process of removing an old outdated lamp post from my front yard as it is both unsightly and non-working. A few months ago I mapped out all of the circuits in my home and determined that the lamp post was connected to the same circuit as my living room receptacles and all outside receptacles. There are a total of 7 interior receptacles and 4 outdoor receptacles on this circuit in addition to the lamppost that I removed. When I opened the breaker box to shut-off the circuit I noticed that it was on a 30-amp breaker. I thought all household lighting and receptacle circuits were supposed to be either 15 or 20 amp circuits. Should I consider replacing the breaker with a 20 amp? Is this a possible fire hazard? FYI, all of the wiring on this circuit is 12 gauge.

If all of the wire on the circuit is 12, you can use a 20A breaker.

You are correct..general lighting and receptacle outlets can not be larger than 20A circuits. If all the wiring is 12 ga, you can use up to a 20A breaker. Yes, you should replace it with a 20A brkr (or a 15A if you so chose).

Just because you can, doesn't always mean you should
