What a Noisy Switchboard Is Telling You
A switchboard should run silently. Buzzing, humming, or crackling almost always means a loose connection, an overloaded circuit, or arcing inside the board, a genuine fire-risk sign under AS/NZS 3000. You are right to take this seriously and get it looked at.

Common Causes of a Noisy Breaker Box
A loose terminal connection
Vibration and age can loosen the screw terminals inside a switchboard, causing arcing and an audible buzz or crackle at that connection point.
A failing or overloaded breaker
A breaker straining under a heavy load, such as a home workshop or large appliance circuit, can hum or click as it struggles to carry the current.
Arcing inside the board
Arcing produces a distinct crackling or sizzling sound and is one of the more serious causes, often needing urgent board replacement.
An ageing ceramic fuse board
Original fuse boards in Boolaroo's older Main Road cottages were not built for modern loads and can hum or rattle under everyday strain.
Is a Noisy Breaker Box Dangerous?
Yes, this is one of the electrical faults you should never ignore. Buzzing, humming, or crackling from a switchboard is a genuine fire-risk sign and warrants a same-day inspection.
- Any sustained noise from the switchboard should be treated as urgent
- Warmth or a smell alongside the noise raises the risk further
- Switch off the main switch if you can safely reach it, and stop using the board
- An old board with loose fuses no longer meets AS/NZS 3000 requirements

What To Do Right Now
A noisy switchboard needs fast, careful handling. Here is what is safe to do while you wait for us:
- Switch off the main switch at the board if you can safely reach it.
- Avoid using power points or circuits near the switchboard in the meantime.
- Do not open the switchboard cover or touch any wiring yourself.
- Do not attempt to tighten or adjust any connections inside the board.
- Call a licensed electrician (Lic #451348C) straight away.
