Answer - The most common reason circuit breakers make noise is the loss of tension on the electrical bus in the panel. The circuit breaker requires a tight connection between the circuit breaker and the bus an if that is not the case, arcing occurs. As the arcing continues more of the required material on the circuit breaker and buss is lost and eventually the breaker contact point is lost. It is very important to note if you hear anything like this in your electrical panel, call an electrician immediately to reduce damage to your electrical panel. more
