What That Noise From Your Switchboard Means
A switchboard should run silent. Buzzing, humming, crackling, or clicking usually means a loose connection, a failing breaker, or arcing inside the board itself, which generates heat as current arcs across a gap. Under AS/NZS 3000, this is treated as an urgent fault, not background noise to tolerate.
Common Causes of a Noisy Breaker Box
A loose terminal connection
The most common cause. A screw terminal that has worked loose over time lets current arc slightly every time it flows, producing a buzzing or crackling sound at that point.
A failing circuit breaker
An ageing breaker can develop internal wear that causes it to hum or click under load, a sign it is no longer switching cleanly and should be replaced.
An overloaded switchboard
Georgetown's older cottages were built with far fewer circuits than modern homes need, so boards carrying more load than designed can hum audibly under strain.
Ageing ceramic fuses
Many Georgetown properties from the suburb's 1850s to 1940s cottage era still run original ceramic-fuse switchboards, and these older fuse carriers are prone to loosening and arcing with age.
Is a Noisy Breaker Box Dangerous?
Yes. Buzzing, humming, or crackling from a switchboard is one of the clearer fire-risk signs an electrical system can give, since it usually means active arcing or overheating inside the board.
- Any buzzing, humming, or crackling from the switchboard should be treated as urgent
- Warmth or a burning smell near the board alongside the noise means active overheating
- A board still using original ceramic fuses with no safety switches no longer meets AS/NZS 3000
What To Do Right Now
These are safe containment steps only, while you wait for a licensed electrician:
- Avoid touching or opening the switchboard yourself.
- If you can safely do so, switch off the main switch at the board.
- Note which section of the board the noise seems to come from.
- Do not reset any tripped breaker that is also buzzing or crackling.
- Call a licensed electrician (Lic #451348C) straight away.
