Why Does My Power Keep Tripping?
If your safety switch keeps tripping, you're not alone — it's one of the most common electrical complaints from Newcastle homeowners. But don't just keep resetting it. A repeatedly tripping circuit is your electrical system telling you something is wrong.
What Causes a Safety Switch to Trip?
Safety switches (RCDs) detect current leaks and cut power to prevent electrocution. Common causes include: faulty appliances leaking current, moisture in outdoor power points, damaged wiring behind walls, overloaded circuits drawing too much power, and insulation breakdown in older wiring.
The Appliance Test
The quickest way to find the culprit is to unplug everything on the affected circuit, reset the safety switch, then plug appliances back in one at a time. If the switch trips when you plug in a specific appliance, that's your problem. Common offenders include kettles, toasters, washing machines, and heaters.
When It's a Wiring Problem
If the switch trips with nothing plugged in, the fault is likely in your home's wiring. This requires a licensed electrician with specialised testing equipment to locate and repair the fault. Don't ignore this — wiring faults can cause fires.
Overloaded Circuits
Older Newcastle homes often have fewer circuits than modern homes need. Running a heater, kettle, and microwave on the same circuit can overload it and cause tripping. The solution is adding dedicated circuits to distribute the load.
Moisture and Water Damage
After heavy rain or storms, moisture can enter outdoor power points, junction boxes, or damaged cable entry points. This causes current leakage and triggers the safety switch. Weatherproof covers and proper sealing prevent this.
When to Call an Electrician
Call a licensed electrician if: the switch trips with nothing plugged in, it trips repeatedly on the same circuit, you notice burning smells, power points are warm or discoloured, or if your home has never had a safety switch inspection. We provide fast, affordable fault-finding across Newcastle.
