What a Power Outage Is Telling You
A power outage affecting just your home, not the whole street, means the fault is inside your property. It could be a tripped main switch, an overloaded circuit, or damaged wiring. Under AS/NZS 3000, we find exactly where the fault sits before touching anything.
Common Causes of a Power Outage
When a Cardiff home loses power while the street stays lit, the cause almost always sits behind your own switchboard. Here is what we check first, in order of likelihood.
A tripped main switch or RCD
The most common cause. The safety switch has done its job and cut power to protect you from a fault somewhere in the circuit.
An overloaded circuit
Running a large oven, pool pump, or EV charger alongside everyday appliances can push an older circuit past its limit and drop the power.
A faulty switchboard
Cardiff's post-war and mid-century homes often still run original ceramic fuse switchboards that were never built for today's electrical load.
Damaged or ageing wiring
Brittle or undersized wiring in Cardiff's older fibro and weatherboard homes can fail under load, especially where renovations have added new circuits.
A failed appliance
An appliance with an internal fault can trip the whole board the moment it is switched on, cutting power to the rest of the house.
A network or supply-side issue near the meter
Occasionally the fault sits closer to the meter box than the internal switchboard, which is where a Level 2 ASP inspection separates a Cardiff household issue from an Ausgrid network issue.
Is a Power Outage Dangerous?
Take a power outage at just your property seriously. It usually means a real fault, and if reset attempts fail or you notice warmth or smell, that points to a genuine risk.
- A main switch that will not stay reset points to a fault, not a nuisance trip
- Warmth, buzzing, or a burning smell alongside the outage is a fire-risk sign
- An old fuse board with no safety switches leaves you unprotected under AS/NZS 3000
What To Do Right Now
If your power has gone out at your Cardiff home, stick to these safe steps until a licensed electrician can inspect it properly:
- Check whether it is your whole home or just part of it, and check neighbouring homes.
- Try resetting the main switch or tripped RCD once at the switchboard.
- If it trips again immediately, leave it off and unplug recently used appliances.
- Do not open the switchboard or attempt any wiring yourself.
- Call a licensed electrician (Lic #451348C) to find and fix the fault properly.
When To Call an Electrician for a Power Outage in Cardiff
- The main switch will not stay on after resetting it once
- Only part of your home has lost power and the cause is not obvious
- There is any burning smell, warmth, buzzing, or scorching nearby
- The outage started after a storm or a power surge
- Your switchboard still uses old ceramic or rewireable fuses
Any of these at your Cardiff property is a job for a licensed electrician, not a reset. We respond same-day and 24/7, with $0 call-out and free quotes. See our electrical repairs and switchboard upgrades.

Common questions
Power Outage FAQs
Real questions Cardiff homeowners ask about losing power at home, answered honestly so you know what to do next.
Is a power outage at just my house dangerous?
It can be. A tripped main switch is usually safe, but a fault behind the tripping, like damaged wiring or a failed connection, can be a fire or shock risk.
What causes a power outage in one house?
A tripped main switch or RCD, an overloaded circuit, a faulty switchboard, damaged wiring, or a failed appliance are the most common causes.
What should I do if my power goes out but my neighbours still have power?
Check your switchboard for a tripped switch, unplug any appliance that was running, and call a licensed electrician if resetting it does not hold.
Do I need an electrician for a power outage, or can I just reset the switch?
You can safely try resetting the main switch once. If it will not stay on or trips again, that is a fault only a licensed electrician should find and fix.
How much does it cost to fix a power outage?
It depends on the cause, but we offer a free quote and fixed upfront pricing before any work, plus a $0 call-out fee for the inspection.
Are ageing switchboards a common cause of power outages in older Cardiff homes?
Yes. Many Cardiff homes from the post-war and mid-century era still run original ceramic fuse switchboards that are prone to overload and dropouts.
