What a Blown Fuse Is Telling You
A blown fuse means a circuit has drawn more current than it can safely carry, and the fuse has done its job by cutting power before real damage occurred. On an older ceramic or rewireable board, common across Narara's mid-century streets, this often means the switchboard itself is overdue an upgrade to meet AS/NZS 3000.
Common Causes of a Blown Fuse
An overloaded circuit
The most common cause. Running a large oven, EV charger, or workshop equipment on one circuit can push it past its limit and blow the fuse.
A short circuit
A fault where wiring touches together directly draws a sudden surge of current, blowing the fuse instantly to protect the circuit.
A faulty appliance
An appliance with an internal fault will blow the fuse the moment it is switched on, until it is unplugged and isolated.
An ageing rewireable fuse board
Older Narara homes often still run original ceramic fuse boards with no safety switches, which blow more readily under today's electrical loads.
Corrosion at the fuse holder
Older fuse holders can corrode or loosen over decades, weakening the connection and making the fuse more prone to blowing.
Adding a large new appliance
Installing an EV charger, spa, or large oven without checking the existing board's capacity often reveals just how marginal an old fuse board really is.
Is a Blown Fuse Dangerous?
Usually a blown fuse is the board protecting you as intended, but one that blows repeatedly points to a fault, and an old fuse board with no safety switches is a genuine safety gap.
- A single blown fuse is normal; one that blows again and again points to a real fault
- Warmth, buzzing, or a burning smell alongside a blown fuse is a fire-risk sign
- A rewireable fuse board with no safety switches no longer meets AS/NZS 3000
- Fuses that blow every time a large appliance runs suggest the circuit is undersized
What To Do Right Now
If a fuse has blown at your home, these are the safe steps to take before we arrive:
- Unplug the appliance that was running when the fuse blew.
- Avoid replacing fuse wire yourself, this is licensed electrical work.
- Do not keep forcing a fuse to hold if it blows again immediately.
- Do not open the switchboard or touch its internals yourself.
- Call a licensed electrician (Lic #451348C) to find and fix the fault.
When To Call an Electrician for a Blown Fuse in Narara

Why This Is Common in Older Narara Homes
Narara's 1960s-1980s brick-veneer and fibro homes often still run original ceramic fuse switchboards, which blow more readily as renovations, EV chargers, and other modern appliances add to the load without a matching upgrade.
Blown Fuses and Related Electrical Faults Across Narara

Common questions
Frequently Asked Questions
Straight, honest answers to the questions Narara homeowners ask most often about a blown fuse, from what causes it to whether an old fuse board needs upgrading.
Is a blown fuse dangerous?
Usually not on its own, but a fuse that blows repeatedly points to an overload or fault, and an old fuse board with no safety switches is a real safety gap.
What causes a blown fuse?
An overload, a short circuit, a faulty appliance, or an ageing rewireable fuse board with no safety switches are the most common causes.
What should I do if a fuse has blown?
Unplug the appliance that was running, avoid replacing fuse wire yourself, and call a licensed electrician if it keeps happening.
Do I need an electrician to fix a blown fuse?
Yes. Replacing fuse wire safely and finding the underlying cause needs a licensed electrician, especially on an older rewireable board.
How much does it cost to fix a blown fuse?
We provide a free quote and fixed upfront pricing after inspecting the board, plus $0 call-out fees, so the cost is clear before we start.
Are old fuse boards common in older Narara homes?
Yes. Many Narara homes from the 1960s-1980s still run original ceramic fuse switchboards that predate modern safety switches.
