If your breaker is sparking it could be loose on the bottom center where it connects to the busbar. The wire going out to the circuit could be loose under the screw terminal. Your breaker should not spark under normal usage. If it continues to spark, you should replace it. When turning off a breaker you are interrupting the flow of current in the circuit, which would create a spark, because the current wants to continue flowing. However, the spark is contained inside the breaker where you cannot see it.
