Your electrical panel controls the power supply in your home while keeping you safe from electrical hazards. Hence, any annoying or worrying sounds from the panel could indicate problems of different kinds. See what these noises could be and what they might mean below.
- A light buzzing sound
By a light buzzing sound, we mean a faint buzzing sound from your breaker. It’s not the type to keep you up at night or be highly noticeable. The cause is often current flowing through the breaker, like water flowing in some direction. This light buzzing sound is generally normal and harmless. But, if it gets louder or involves clicking and other horror-movie sounds, be sure to call an electrician.
- Medium humming sounds
This sound is louder and more obvious than a light buzzing sound. It can take various forms such as a sizzling noise, sparking, a clicking noise, or a humming breaker. So you can hear sizzling sounds with occasional sparks and this certainly means something is wrong with the circuit breaker. The cause may be frayed and loose wiring which is incredibly dangerous and an electrical hazard. It is necessary to call an experienced electrical technician to replace and repair the wiring quickly.
- Loud and continuous buzzing sounds
Now, this is what keeps you up at night. Constant loud buzzing sounds can be disturbing because they are loud. The cause often stems from the breaker not tripping when it should, and this, in turn, indicates that the breaker is bad. Your electric breaker shuts off the power supply during a power surge to protect your home. But when it fails to do this the flow of current to the wires increases leading to a buildup of heat, the loud buzzing sound, and an electrical hazard. Circuit breakers go bad for several reasons such as wear and tear and a faulty panel. This humming noise should not be ignored, and an electrician should be called immediately.
A buzzing and humming sound is normal if…
The sound isn’t loud as we have described above.
If the buzzing sound starts right when your AC comes on but stops once the appliance is working smoothly.
Trying to solve this electrical issue yourself can be very dangerous. Therefore the first and safest way to solve humming and buzzing noise from your electrical panel is to call a licensed and experienced electrician.
