Safety switches are for one extremely important reason; they are speciﬁcally made to save lives. It is highly important that you have safety switches installed on your circuits, you should also know where your safety switch is and how to test it. If you don’t have them or don’t know how to use an RCD please contact us so we can help your house become as safe as possible.
The facts: Did you know that every year in Australian houses, 15 people are killed due to electrical accidents that could have been prevented if a safety switch was installed to the electrical circuit. On top of that up to 300 people are hospitalised with serious electrical injuries and burns.
Safety switches – are also known as residual current circuit breakers (RCCBs) or residual current devices (RCDs) – have been in common use in Australia for over 20 years. Safety switches are different to overload circuit breakers and surge protectors.
A safety switch will detect a current leaking to earth and will trip the circuit within as little as 30 milliseconds, and no more than 300 milliseconds. This stops the ﬂow of electricity through the body of the person in contact with the circuit, in less than the length of a critical heartbeat.
