My Safety Switch has tripped… What should I do NOW !?

A Simple step by step guide to fault finding a tripped Safety Switch.

Note: Some types of appliances may cause incidental or nuisance tripping of your Safety Switch or RCD device. Typically Water Heaters, Electric Jugs and Kettles, Steam Irons, Dishwashers, washing Machines, Swimming Pool Equipment, Auto Defrost Refrigerators and Freezers.
Most Important: If your Safety Switch has turned off, it has done so for a reason. It has detected a leak of some electricity. This may be through a faulty appliance or it may be a fault in the house wiring. These instructions will help you find that leak.

1. First try to turn the Safety Switch on.[Marked Residual Current Device]
2. If it stays on then the fault was intermittent or transient and we can do nothing at this stage. Refer to Note above.
3. Think of what you were using at the time.
If the Residual Current Device trips off again, got to point 5.
4. Turn on the Residual Current Device.
5. If it won’t stay on then you will have to unplug all appliances!
This includes any outside power points or power to outbuildings.
6. At this point the Residual Current Device should stay on. [If not you will need to call an Electrician.]
7. If the Residual Current Device stays on then turn the Circuit Breakers on one at a time.
8. When you come to the leaking circuit, the Residual Current Device will turn off.
9. Unplug all appliances that are plugged in to power points that do not work.
Turn the Residual Current Device on. If it won’t stay on then you will have to call an Electrician.
10. If it stays on, then one of the appliances you have unplugged is faulty. Plug the items in, one at a time until you find the faulty one.

Remember Do not fix any Electrical device yourself, give the device to a suitably qualified electrical repair workshop or if under warranty consult with the manufacturer for the possibility of repair under those warranty conditions.

The Electrical Switchboard your backup defence in electrical safety.

Fuses, Circuit Breakers and Safety Switches

These devices are found in your Switch board understanding these devices and how to use and maintain them will help  your management and understanding of Electrical Safety in the Workplace.

Primary Overload response devices (Fuses & Circuit Breakers)

Fuses and circuit breakers are built to fail in conditions of excess current which can overload the electrical wires in your home. These overloads are often caused by faulty appliances. When an overload occurs, the fuse melts before the wires can overheat, which reduces the risk of fire. Circuit breakers will often trip quicker and more importantly they can be reset to help diagnose and remove faults

  1. Always replace a blown fuse with the correct fuse wire. Never use fuse wire that is heavier than the recommended gauge.
  2. Never use any other type metal or wire.
  3. If fuses keeps blowing, or a circuit breaker keeps tripping, check that your appliances are not faulty.
  4. If fuses continue to blow, or circuit breakers continue to trip after appliances are unplugged, there could be a problem with your wiring. Contact a licensed electrician immediately.

Safety switches and RCD devices

Safety switches or RCD device look similar to circuit breakers and will have a test button to provide a test for the correct earth tripping of the device. The purpose is to they provide extra protection from electric shock. Safety switches monitor the flow of electricity and if any irregularity is detected, the electricity supply is immediately cut off.
Homes with children or backyard workshops should consider installing safety switches to reduce the risk of electrical accidents. It is imperative that commercial premises have them installed and tested regularly.. New homes and Commercial premises are required to have safety switches installed. Licensed electrical contractors can install safety switches in older homes at a reasonable cost. You can also purchase portable safety switches for appliances and extension cords. Useful particularly when using power tools outside ie Electric Lawnmowers, Hedge trimmers, Drills, circular Saws etc  and these portable RCD should also be tested on a regular Basis!

Fixed RCD testing… Why is it important?

At every workplace there is at least one Electrical switch board that is built to divide the power and lighting into manageable circuits feeding, lights, equipment and power points for us to use. Though we may not have an understanding electricity, it is important that you know about the little understood device called the RCD (residual current Device) or sometimes referred to as the Safety Switch that will find amongst the breakers and or fuses in this panel.

An RCD is an electromechanical device,that detects any shunting of electrical power to earth thereby shutting the circuit down in mere milli-seconds, in doing so avoiding electrocution to personnel and possible fire hazards.

Being and Electromechanical device ,it can like any other similar device be prone to failure. As part of a regular testing check, it needs to have a push button test which basically is a test every 6 months to check out the mechanical workings of the RCD of which any body can do. If there are breakers on your Panel that are RCD’s.. the give away is a breaker with a button for testing also on the breaker are the words 30ma RCD… these are the devices that need to be tested monthly by push button. Picture below

But this is a bit like push button testing a battery smoke alarm it only test the resultant action it doesn’t test the actual detection part of the device.

So periodically you need to have your fixed Main switchboard panel RCD’s tested with a calibrated RCD tester, and if it responds with a shutdown time lag of less than 299 mill-seconds… typical times for most RCD’s are usually are 5-50 milliseconds… here is a table below which will help
