Power Points Not Working But Lights Still On? Here’s What That Means

It feels like a contradiction. The room is lit, everything looks normal, and nothing you plug in works. It isn’t a contradiction, and it isn’t random. It’s your wiring doing what it was designed to do.

This guide explains why it happens, what the pattern of dead outlets tells you, and where the line sits between what you can safely notice and what needs a licensed electrician. If there is any burning smell, heat, sparking or a shock involved, skip to the urgent section.

Why lights stay on when power points die

Homes are wired with lighting and power points on separate circuits, each with its own protection at the switchboard. So a tripped breaker, a tripped safety switch or a fault on a power circuit takes out the outlets while the lights carry on.

In a lot of Queensland homes there is a second reason. The Electrical Safety Office records that safety switches have been compulsory on power point circuits in new homes since 1992, and on lighting circuits as well since 2000. In a home from that first period, the safety switch often protects the power points and nothing else. When it trips, every outlet goes dead and every light stays on.

The two devices also react to different things. In the ESO’s words, “circuit breakers are installed to protect circuit wiring and appliances, while safety switches protect people.” Either one switching off is the system reporting a problem, not causing one.

Start here: how much is actually dead?

The scope of the outage narrows the diagnosis more than anything else. You can work this out without touching the switchboard: just notice which outlets have stopped working.

If the lights are out as well, or the whole street is dark, that’s a different situation. See what to do during a power outage.

What you can safely do, and where to stop

A dead outlet or a tripped switch means something has gone wrong on that circuit, and you can’t see what from the outside. The safe things are the ones that involve looking, not touching:

1. Note which outlets are dead. One, a few in one area, or all of them. This is the most useful thing you can tell an electrician.
2. Note what was happening. Was something just plugged in or switched on? Has it been raining? Did it happen once or does it keep happening?
3. Look at the switchboard without touching it. If a switch is sitting in a different position from the others, note which one and how it’s labelled.
4. Call a licensed electrician. Tell us what you’ve noted. We can tell you over the phone whether anything is safe to try, and talk you through it if it is.

That last step is deliberate. A switch that has tripped has tripped for a reason, and the ESO’s guidance is that a safety switch you can’t reset may mean there is a fault on the circuit that needs a licensed electrician to inspect and repair. Resetting against a live fault, or moving a suspect appliance to another outlet to test it, is how a manageable problem becomes a dangerous one. If you’re in any doubt, leave everything as it is and call.

Beyond that, the law is clear. The ESO states that DIY electrical work is regarded as unlicensed electrical work, which is illegal, with penalties of up to $40,000 for individuals. Any work on the outlet itself or the wiring behind it is a job for a licensed electrician, however simple it looks. Our guide to what you can legally do yourself covers where that line is.

The five causes behind dead power points

1. A tripped breaker or safety switch. The usual one. It’s often triggered by a specific appliance, such as a heater, a kettle or something with a developing internal fault. If it keeps happening, see why a switchboard keeps tripping.
2. A faulty appliance leaking to earth. The safety switch is doing its job. Our guide to why safety switches keep tripping explains what it’s detecting.
3. A failed or burnt-out outlet. Internal contacts wear, terminals loosen and connections degrade, particularly on outlets that get a lot of use. This is the usual answer when exactly one outlet is dead, and replacing the outlet is normally a straightforward job for an electrician.
4. Water in an outdoor outlet. Common here in storm season. Rain gets into an outdoor power point, current leaks to earth, and the safety switch cuts the whole circuit, including indoor outlets that share it. The giveaway is the timing: it started during or after wet weather. Salt makes it worse, as we explain in how salt air kills outdoor power points.
5. A loose or degraded connection in the wiring. The least common and the most serious. A loose terminal at an outlet or in the switchboard can cut supply to everything after it, and the loose joint can generate heat. This is the one that can become a fire risk if left, and it’s why a dead circuit with no obvious cause shouldn’t be ignored.

When it’s urgent rather than annoying

If anyone has been hurt by a shock, or there is smoke or fire, call 000 first. For everything else on that list, keep people away from the affected outlet and call our 24/7 emergency electrician line. We’ll tell you what to do while we’re on the way.

Our guide to a burning smell from a power point covers that situation specifically, and what’s considered an electrical emergency sets out where the line is.

Why it keeps happening

When power points drop out repeatedly, the cause often sits upstream of the outlets themselves.

• An overloaded circuit. Households run far more on their power circuits than older boards were laid out for, and a circuit close to its limit trips when demand peaks. See how much you can safely plug into one power point. The lasting fix is often adding power points on a separate circuit.
• Too many circuits behind one safety switch. Small background leakage from many devices adds up and creeps toward the trip point. The guide to RCDs versus RCBOs explains why protection on each circuit helps avoid this, and safety switch installation is how it gets added.
• A safety switch that isn’t working properly. Uncommon. The ESO says a safety switch should last a lifetime unless there is a significant problem with the device. Proper safety switch testing settles it.
• Deteriorating wiring. In older homes, insulation that is breaking down can produce faults that come and go with heat and humidity. It’s one of the common electrical problems in older QLD homes.

Repeated trips on the same circuit are worth having diagnosed properly. A reset treats the symptom. Fault finding with test equipment finds the cause.

On the Gold Coast the wet-weather version is the one to take seriously. Outdoor outlets near the coast, from Palm Beach to Burleigh Heads, can lose their seals faster in salt air, and the problem tends to return with the next storm until the fitting is fixed.
