Burning Smell Near Your Powerpoints? Don't Ignore It
That acrid odour coming from a powerpoint is a warning sign — here's what it means, the mistakes people make, and when to call a licensed electrician.
What does a burning smell near a powerpoint actually mean?
A burning smell near a powerpoint almost always means something is overheating — either the wiring behind the outlet, the outlet itself, or a connected appliance. It is not a quirk to monitor over time; it is an electrical fault that can escalate to a house fire.
The smell is typically caused by arcing (electricity jumping across a gap), a loose or corroded wire connection, or insulation melting around conductors. In older homes across Sutherland Shire — particularly those that haven't had a switchboard upgrade or home rewiring in decades — deteriorated wiring is a common culprit.
Some burning smells are faint and intermittent, others are sharp and constant. Neither version is safe to live with. The intensity does not reliably indicate how serious the underlying fault is.
Mistake #1: Assuming it's the appliance, not the wiring
The most common mistake homeowners make is unplugging the appliance that was in the socket, noticing the smell goes away, and concluding the problem is solved. It isn't. The appliance may have triggered an existing fault — a loose terminal, an undersized circuit, or damaged insulation — that will arc again the moment any load is placed on that outlet.
What to do instead: unplug everything from that powerpoint and do not use it again until a licensed electrician has inspected it. If the smell persists even with nothing plugged in, that is a serious sign of active arcing or smouldering insulation inside the wall cavity.
Replacing the appliance while leaving a faulty outlet in place is like changing the lightbulb when the socket is the problem.
Mistake #2: Thinking a safety switch will protect you from this fault
Safety switches (RCDs) protect against current leaking to earth — they are lifesaving devices for electric shock prevention. However, they do not trip in response to overheating connections, arcing faults between active and neutral, or insulation that is slowly degrading. A burning smell can exist on a circuit that has a functioning safety switch.
This is a dangerous misconception that gives homeowners false confidence. Arc fault circuit interrupters (AFCIs) are designed to detect arcing faults, but they are not yet standard in Australian homes. Most residential switchboards in suburbs like Miranda and Caringbah rely on traditional RCDs and circuit breakers, neither of which will necessarily respond to the fault causing your burning smell.
If you have a safety switch installed and still notice a burning smell near an outlet, that does not mean the fault is minor — it means the protection you have is not designed to catch that type of fault.
Mistake #3: Trying to inspect or fix it yourself
Opening a powerpoint to investigate a burning smell is illegal for unlicensed persons in NSW and genuinely dangerous. Behind a discoloured or warm outlet, you may find conductors that are live and physically degraded — scorched insulation, loose terminals under spring tension, or wiring that crumbles when touched. Disturbing that wiring without proper tools and training can cause immediate arcing or shock.
The correct action is straightforward: switch off the circuit at the switchboard if you know which one controls that area, and call a licensed electrician. Do not attempt to swap the outlet yourself, even if you've watched a tutorial. Power point installation and fault diagnosis involve identifying the root cause in the broader circuit, not just swapping the visible fitting.
For homeowners in Gymea, Engadine, Menai, and surrounding areas, PTY UNLIMITED PTY LTD can attend, isolate the fault, and advise whether a repair, partial rewire, or switchboard upgrade is the right fix.
Mistake #4: Waiting to see if it gets worse before calling anyone
Electrical fires can start inside a wall cavity and burn for minutes before smoke becomes visible in the room. Waiting to see whether a burning smell worsens is one of the costliest delays a homeowner can make — both financially and in terms of safety.
The myth behind this mistake is that if nothing has tripped and the lights are still on, the situation is stable. Arcing faults do not always draw enough current to trip a breaker, particularly in the early stages. The fault can smoulder intermittently, especially when specific appliances are used, ambient temperature rises, or the connection shifts slightly.
If your smoke alarms are older or not photoelectric, they may also not detect a slow-burning electrical fault at the wall until smoke is already heavy. Smoke alarm installation using current photoelectric technology is one of the most straightforward steps you can take to add a second layer of detection — but it does not replace fixing the underlying electrical fault.
