Overloaded Power Points, Explained in Plain English
A power point crowded with double adaptors, power boards stacked on power boards, or one that's simply warm to touch is a common sight in most homes. It's also worth taking seriously.
If any point feels genuinely hot, smells odd, or has visible discolouration, stop using it and call (02) 9538 7139 now.
What an Overloaded Power Point Actually Means
Every power point and the circuit behind it has a rated current limit. Overloading means asking that point to carry more than it was designed for, usually by stacking multiple devices onto a single outlet.
Adaptors, power boards and double adaptors don't add capacity. They add connection points, and each connection adds a little resistance.
Resistance under sustained current means heat, and heat is where the real risk starts.
None of this means adaptors are banned. It means the point behind them needs to actually cope with what's plugged into it.
Common Causes of an Overload
- Multiple boards plugged into each other. Multiplies the load a single point carries well beyond its design.
- Too few circuits for modern appliance demand. Common in older homes built long before multiple screens and chargers per room was normal.
- High-draw appliances sharing one point. Heaters, kettles and similar appliances draw heavily on their own.
- A single circuit feeding too many rooms. Spreads demand thin across a run not built for it.
- Worn power points losing grip on plugs. Poor contact generates heat even without excess load.
Is an Overloaded Power Point Dangerous?
Yes, treat any warmth, smell or discolouration as urgent. A point that's simply crowded with adaptors but still running cool is a warning sign rather than an immediate danger.
The moment it runs warm, that risk has already started. Get in touch quickly if you notice heat, a smell, or a point that's begun tripping repeatedly.
A crowded but cool point is worth addressing soon, spreading the load properly, but doesn't need an emergency call.
What To Do Right Now
- Unplug non-essential devices from any point that feels warm or overloaded.
- Remove stacked adaptors and power boards where you can safely reach them.
- Check for heat, smell or discolouration at the point itself.
- Call (02) 9538 7139 if there's any warning sign beyond simple crowding.
How We Fix It, Step by Step
We start by identifying which points and circuits are carrying the heaviest load, then test for heat and connection quality with thermal imaging.
Where a point itself is worn or damaged, we replace it. Where the real issue is too much demand on too few circuits, we talk through adding properly wired points elsewhere in the room.
For homes running genuinely tight on circuits, a switchboard assessment often makes more sense than patching individual points one at a time.
Where the job is notifiable, it's tested and carries a Certificate of Compliance, with the price set in writing before anything begins.
Why Older Mount Colah Homes See This Often
Streets built around the original Mount Colah Public School precinct, established back in 1953, carry housing stock from well before today's device count was ever anticipated.
A household running one TV and a radio in the 1960s looks nothing like one running a TV, streaming box, gaming console and chargers off the same point today.
That gap between original circuit design and modern demand is exactly where overloaded points show up first, especially in living rooms and home offices.
It's rarely a sign anything was done wrong originally. It's simply a house built for a different era of appliance ownership than the one it's living through now.
How to Stop It Happening Again
- Add properly wired power points where demand has genuinely outgrown supply.
- Spread heavy appliances across separate circuits instead of one shared run.
- Avoid stacking adaptors and power boards, using multi-outlet boards with overload protection instead.
- Have an older switchboard assessed if overload symptoms recur across different rooms.
- Have heavily used points checked from time to time, especially ones under constant daily load.

An overloaded point that's already scorched belongs on our page about a heat-damaged power point, and a circuit that trips under that load is covered under a circuit breaker that won't hold.
If the smell of hot plastic is involved rather than just warmth, see a burning electrical smell for the urgent guidance there.

Common questions
Your Overloaded Power Points FAQs
Why does only one power point in the house feel warm?
Warmth at one point usually means that specific circuit or point is carrying more than it's comfortable with, often from double adaptors or power boards stacked together. Other points on different circuits stay cool because they're not sharing the same load.
Is a double adaptor actually dangerous?
It can be, especially stacked adaptors or power boards plugged into power boards. Each connection adds resistance and heat, and a single point was never designed to carry that many devices at once.
How many circuits should a modern home have?
It depends on the size and age of the house, but older homes built before higher power demand was standard often have fewer circuits than a comparable new build. That's a common driver of overload symptoms.
Can overloaded points cause a fire?
Yes. Sustained heat from an overloaded point or circuit is a genuine fire risk, particularly if it goes unnoticed behind furniture or under a desk.
Will a safety switch stop an overload?
A safety switch protects against shock, not overload itself, though a circuit breaker will trip under a severe overload. The two protections work together but aren't interchangeable.
Do I need more power points or just less load?
Usually both help. Adding properly wired points spreads devices across more circuits, and being deliberate about what shares a point reduces strain on whatever's left.
