Hearing buzzing or humming from your switchboard in Kanwal? Electrician Kanwal treats this as urgent, inspects it fast, and fixes it properly, backed by Lic #451348C and 300+ five-star reviews.
What a Noisy Switchboard Is Telling You
Buzzing, humming, crackling, or clicking from a switchboard or meter box means current is arcing or a connection has come loose, and it should never be dismissed as background noise. Under AS/NZS 3000, a switchboard should run silently, so any noise is a genuine fault worth an urgent look.

Common Causes of a Noisy Switchboard in Kanwal Homes
A loose connection
The most common cause. A terminal inside the board has worked loose over time, letting current arc slightly every time it is under load.
A failing breaker
An ageing circuit breaker can start to hum or click as its internal contacts wear, especially under a large oven, EV charger, or workshop load.
Arcing inside the board
Genuine arcing between components generates heat and noise and is a fire-risk sign that needs the board isolated and checked.
An overloaded switchboard
Many Kanwal homes from the 1970s and 1980s still run original boards, and pushing modern appliance load through them can cause audible strain.
Is a Noisy Switchboard Dangerous?
Yes, this is one of the clearer fire-risk signs an electrical system can give, and it should be treated as urgent rather than monitored over time.
- Buzzing or humming means current is arcing somewhere it should not be
- Warmth or a burning smell alongside the noise means the fault is progressing
- An old ceramic fuse board with no safety switches no longer meets AS/NZS 3000
- The noise will not stop on its own and tends to worsen under load

What To Do Right Now
Before we arrive, take these safe steps only, this is not something to investigate yourself:
- If you can safely reach it, switch off the main switch at the switchboard.
- Avoid touching or leaning close to the switchboard itself.
- Unplug any large appliance that was running when the noise started.
- Do not open the switchboard, remove covers, or inspect the wiring yourself.
- Call a licensed electrician (Lic #451348C) the same day.

Why This Is Common in Older Kanwal Homes
