A safety switch is designed to save the lives of yourself and your family. Every home in Queensland should have this equipment functioning perfectly. You as the house owner need to test this as well. This can be done by pressing the TEST button on your safety switch.
When the test button is pressed and earth fault is put across the internal coil of the safety device which should in turn trip out the device. If this doesn’t occur you may have a non-functional device and you will need to have it seen to by a qualified electrician.
