The 30 amp breaker you have is ok as long as you have the correct wire size, 14 guage - 15 amp breaker, 12 guage - 20 amp breaker, 10 guage - 30 amp breaker.
This is the wire size and breaker size per unified building codes and only for copper wire.
It sounds like you have a branch circuit and some one may have swapped breaker out, you need to find out wire size and put correct breaker in. I run two 10 guage conductors for each hot, nuetral and ground with 30 amp breakers, the two 10 guage wires doubled up is about 7 guage wire but I have amps that put out around 1600 watts each! Happy Listening!
