What That Switchboard Noise Really Is
Buzzing, humming, crackling or clicking from a switchboard or meter box usually means a loose connection, a failing breaker, or arcing inside the board. Under AS/NZS 3000, this is not something to leave, and getting it checked properly protects both your home and your family.
Common Causes of a Noisy Breaker Box
A loose connection
A terminal or connection inside the board that has worked loose over time can arc under load, producing the buzzing or crackling you hear.
A failing breaker
An ageing breaker can develop internal wear that causes clicking or humming as it struggles to carry the circuit's load reliably.
Arcing at a terminal
Electrical arcing generates heat and noise, and is one of the more serious causes behind a buzzing switchboard that needs urgent attention.
An overloaded board
Many Cardiff Heights homes built through the 1940s-1960s ridge development run boards that were never designed for today's appliance load.
Corroded or degraded wiring connections
Ageing wiring in long-held homes can corrode internally at the connection point, adding resistance that shows up as heat and noise.
Is a Noisy Breaker Box Dangerous?
Take it seriously. Buzzing or humming from a switchboard is one of the genuine fire-risk signs in a home and should be checked properly, not left to see if it settles.
- Any buzzing, humming, crackling or clicking from the board should be treated as urgent
- Warmth or a burning smell alongside the noise means switch off and call the same day
- An old fuse board with no safety switches no longer meets AS/NZS 3000
- Noise that started suddenly can mean a connection has just failed
What To Do Right Now
If your switchboard is making noise at your Cardiff Heights home, stick to these safe steps until a licensed electrician can inspect it properly:
- Keep the area around the switchboard clear and dry.
- Avoid touching, opening, or investigating the switchboard yourself.
- Note when the noise happens, constantly or only under certain loads.
- Switch off the main switch if you also smell burning or see scorching.
- Call a licensed electrician (Lic #451348C) the same day.

Avoid touching or opening the switchboard, keep the area clear, and call a licensed electrician the same day to have it checked properly.
Do I need an electrician for a noisy switchboard, or will it settle down?
