Do You Have These Indications of a Circuit Problem?
Here are the Symptoms of an Overload Circuit – In a normal situation the circuit breaker is simply doing its job of protecting the wiring from overloading, and this is why circuit breakers should never be replaced by a over sized circuit breaker.
Electrical Circuit Breaker Hums Buzzes and Trips
I have a circuit breaker that hums or buzzes when my microwave is running and occasionally trips the breaker.
- Is the breaker bad?
- Will replacing the breaker solve the problem?

Thanks for your electrical wiring question Terry.
Here are the Symptoms of an Overload Circuit
- This is typically a symptom of an overloaded circuit and an indication that the microwave oven may be on a shared circuit, so replacing the circuit breaker may not be the solution. However due to the hum and buzzing sound I would advise that the circuit breaker and the panel be inspected by a qualified electrician for possible arcing that could be taking place at the connection of the breaker to the panel buss. This could be a deteriorating condition that may require a replacement circuit breaker into a new position in the panel.
- In a normal situation the circuit breaker is simply doing its job of protecting the wiring from overloading, and this is why circuit breakers should never be replaced by a over sized circuit breaker. The number of devices that are on this circuit should be identified and you will most likely find that the circuit capacity becomes overloaded especially when the microwave oven is in use. This is why most microwave ovens require their own dedicated circuit.
