Thanks for your ans. If the breaker buzzes load would the breaker be bad.winnie said:I would consider turning up the radio as one of the fixes.
The high current flow creates a magnetic field which can cause conductors or EMT to vibrate. You hear this noise, but the noise is not much of a problem unless a paying customer objects to it. Breakers can also buzz during acceptable overloads.
Sorry to be probeing so much on this topic, but what would you suggest to do for testing? I am new at troubleshooting and want to give an educated ans. to those it concerns. I've checked all the connections that I know of.brian john said:No a buzzing CB in not necessarily indicative of a bad CB, but it warrants investigation and testing..
