It always seems to happen as you're rushing to get ready for work or when dinner is on the go, the safety switch goes off and most the electrical appliances in the house shut down. The fridge clunks to a halt, the hair dryer stops blowing, and the TV goes blank. Something has tripped the safety switch, which, even though it doesn't seem like it when you're running out the door in a half ironed shirt eating a piece of warm bread, is actually a good thing.
It means this essential home electrical safety device has potentially prevented a fatal accident. Safety switches activate in around .03 of a second cutting the supply of electricity to the circuit fast enough to prevent serious harm from an electric shock.
The safety switch is triggered by a detected change in the flow of electricity through the circuit it is fitted to (in most homes it's fitted to the power point circuit). Many problems can cause this change in flow, common issues can include:
The safety switch tripping can be a nuisance but the fix is usually fairly straight forward.
As we mentioned above if your safety switch trips regularly get it checked out by your electrician to ensure it's working correctly and providing protection for your family from electrical accidents.
