Tripping circuit breakers

I have a few of these circuit breakers tripping in a client’s place of mine. These circuits power an audio rack with a couple of amplifiers and video switchers. I started thinking to myself…these circuit breakers are rated at 16A. You mean, that is not enough for the audio rack? Looks like either these circuit breakers are super sensitive or the current really exceeds what the circuit breaker can handle. Time to get these replaced.
