To switch on a safety switch, you need to locate the tripped switch, which will be in the "off" position, and then simply flip it back to "on."
A safety switch, also known as a Residual Current Device (RCD) or Earth Leakage Circuit Breaker (ELCB), is a vital safety device designed to protect you from electric shock by quickly cutting off power when an electrical fault is detected. When it trips, it indicates a potential issue in your electrical system or an appliance.
Steps to Reset Your Safety Switch
Resetting a tripped safety switch is a straightforward process. Follow these steps carefully:
- Locate Your Electrical Meter Box/Distribution Board: This is typically found on an exterior wall of your home, in a garage, or sometimes inside a cupboard.
- Identify the Tripped Switch: Once you open the meter box or locate your distribution board, you'll see a row of switches. The safety switch that has tripped will be the one currently sitting in the “off” position (down). Other switches will likely still be in the "on" position (up).
- Turn the Safety Switch On: Firmly push the identified tripped safety switch back to its "on" position (up). You might hear a click.
What to Do If the Safety Switch Trips Again
If your safety switch immediately trips again after you reset it, it indicates an ongoing electrical fault. In such cases, follow these troubleshooting steps:
- Unplug Appliances: The most common reason for a safety switch to trip is a faulty appliance. Go through your home and unplug all appliances connected to the affected circuit. This includes fridges, freezers, televisions, computers, toasters, kettles, and washing machines.
- Reset Again: Attempt to reset the safety switch once more.
- Plug in Appliances One by One: If the switch stays on, plug your appliances back in one at a time. When the safety switch trips again, you have identified the faulty appliance. Disconnect it and avoid using it until it's repaired by a qualified technician or replaced.
- Check for Obvious Issues: Look for damaged cords, frayed wires, or any signs of burning on outlets or appliances.
Common Reasons a Safety Switch Trips
Understanding why a safety switch trips can help you resolve the issue efficiently.
| Reason | Description |
|---|---|
| Faulty Appliance | Damaged wiring within an appliance, a broken heating element, or a motor fault can cause current leakage. |
| Overloaded Circuit | While less common for RCDs than circuit breakers, connecting too many high-power appliances to a single circuit can sometimes trigger a trip if there's any leakage. |
| Damaged Wiring | Frayed or exposed electrical wiring in walls, ceilings, or outdoor areas can cause current to leak to earth. |
| Water Ingress | Water entering electrical outlets, light fittings, or appliances can create an electrical path to earth. |
| DIY Installations | Incorrectly installed lights, power points, or appliances can lead to dangerous earth faults. |
| Lightning Strike | A direct or nearby lightning strike can cause a massive surge, tripping all safety devices. |
When to Call a Licensed Electrician
If you have followed the steps above and your safety switch continues to trip, or you cannot identify the cause, it's crucial to contact a licensed electrician. Do not attempt to fix electrical faults yourself, as this can be extremely dangerous. An electrician can safely diagnose the problem using specialized equipment and perform the necessary repairs, ensuring the safety of your home and its occupants.
