⚠️ Constantly resetting your safety switch? It’s a sign something’s not right.
A safety switch (RCD) is a life-saving device that cuts power in the event of a fault. While it’s doing its job, frequent tripping is not normal—and it’s a red flag that needs attention.
In this blog, we’ll explain why your safety switch keeps tripping, what you can do to identify the cause, and when it’s time to call a licensed electrician in Sydney.
🔌 What Is a Safety Switch?
A safety switch monitors the flow of electricity and disconnects power within milliseconds if it detects a leak or fault—preventing electric shocks, fires, and appliance damage.
🧯 Top 5 Reasons Your Safety Switch Keeps Tripping
1️⃣ Faulty Appliances
Appliances like kettles, toasters, and washing machines can develop internal faults that cause leakage currents.
How to test:
- Unplug all appliances.
- Reset the safety switch.
- Plug in each item one by one to identify the culprit.
2️⃣ Water or Moisture In Electrical Points
Water ingress from leaking roofs, damp walls, or outdoor sockets can cause the safety switch to trip.
What to do:
- Check outdoor power points and bathroom circuits.
- Avoid using wet or exposed outlets.
3️⃣ Overloaded Circuits
Running too many high-powered devices on one circuit can overwhelm it.
Signs include:
- Tripping when using heaters or air fryers
- Warm power points or burnt smells
Solution: Spread appliances across different outlets or get an electrical upgrade.
4️⃣ Wiring Faults in Your Home
Damaged or degraded wiring (especially in older homes) can leak current and trip your switch.
This requires urgent attention.
Call a licensed electrician in Sydney to inspect and repair the issue.
5️⃣ A Faulty Safety Switch
Yes, sometimes the switch itself is the problem—especially if it’s old or poor quality.
What to check:
- Does it trip even with nothing plugged in?
- Is it warm or cracked?
Time to replace it with a new, compliant model.
