Breakers should operate quietly. Buzzing is not normal panel background noise — it's a sign something is wrong at that circuit or its connection to the panel.
We identify whether the breaker, its connection, or the circuit load is causing the noise.
Symptoms
- Buzzing or humming from one breaker
- Noise gets louder under load
- Breaker buzzes and feels warm
- Buzz started after storm or power surge
- Lights flicker on the same circuit
Common causes
Several different issues can create similar symptoms. These are the most common causes we see in Leesburg homes:
- Loose breaker connection to the bus bar
- Arcing inside a failing breaker
- Heavy motor load on the circuit
- Loose circuit wire at the breaker terminal
- Breaker near end of service life
What you can safely check
These simple checks may help, but do not open panels, remove devices, or touch wiring. If you notice heat, sparking, or a burning smell, stop and call us.
- Reduce load on the buzzing circuit
- Do not touch exposed panel parts
- Note whether buzz changes when devices turn on
- Call if buzzing is loud or accompanied by smell
What not to do
These mistakes can make the problem worse or create a safety risk:
- Do not ignore buzzing because power still works
- Do not spray lubricants or cleaners into the panel
- Do not tap or jiggle the breaker to stop noise
- Do not add load to a buzzing circuit

Why is my breaker buzzing?
Loose connections, arcing inside the breaker, or heavy load are the most common causes.
Is a buzzing breaker dangerous?
Arcing generates heat. Buzzing breakers should be diagnosed before damage spreads.
Will replacing the breaker stop the buzz?
If the breaker failed, yes — but loose wire connections must be addressed too.
