In short

Ambient Electrical does safety switch installation, testing and repair in Sydney's Eastern Suburbs, either at the switchboard to cover whole circuits or at a single power point. A safety switch, or residual current device (RCD), turns the power off in a fraction of a second when it detects electricity leaking to earth at a harmful level, typically 30 milliamps or less. The NSW Government recommends testing safety switches twice a year.

Safety switches are vital in protecting people against electrocution. They are required on light and power circuits and can be fitted to existing installations.

A safety switch, or residual current device (RCD), watches the current going out and coming back on a circuit. When it detects electricity leaking to earth at a harmful level, typically 30 milliamps or less, as happens when current flows through a person or through a fault to earth, it turns the power off in a fraction of a second.

Ambient Electrical installs, repairs and tests safety switches to the Australian Standards, using switches made by Hager, NHP and Clipsal.

Safety switches can be retrofitted to almost any installation: at the switchboard, protecting every light and power circuit, or on a single power circuit, protecting that point and everything beyond it.

The Wiring Rules (AS/NZS 3000) require a home with more than one final sub-circuit to have at least two safety switches, so that one fault does not black out the whole house.

Fuse, circuit breaker or safety switch: what each protects
DeviceWhat it protectsHow it works
Rewireable (ceramic) fuseThe wiring, against overload and short circuitsA fuse wire melts when too much current flows. It does nothing to protect a person from an electric shock, and blown fuses are often rewired with the wrong gauge of wire.
Circuit breakerThe wiring, against overload and short circuitsSwitches the circuit off when too much current flows, and is switched back on rather than rewired. On its own it does not protect a person from an electric shock.
Safety switch (RCD)People, against electric shockCompares the current going out with the current coming back, and turns the power off in a fraction of a second when electricity leaks to earth at a harmful level, typically 30 milliamps or less.

Safety switch testing

The NSW Government recommends testing safety switches twice a year: press the TEST button on each one and it should switch off straight away. Push it back on and you are done. If it does not trip, it is not protecting you and needs replacing. An electrician tests more thoroughly with an instrument that applies a controlled fault current and measures how fast the switch operates. (Source: NSW Government: Electrical safety in the home)

In a rental, NSW Fair Trading treats a faulty safety switch as an urgent repair. Safety switches can only be installed by a licensed electrician. If yours keeps tripping, start with the appliances on that circuit.

What a customer says about this work

We called Ambient Electrics for what we thought was a small problem. Peter arrived on time and was very friendly. It turned out that we had a serious problem, the safety switch was not connected.We were horrified to think of the times when we could have been electrocuted.Peter explained every step in terms we could understand.If you need an electrician who is professional,congenial and honest we could not recommend Peter highly enough.

Safety switches: common questions

What does a safety switch do?

A safety switch, or residual current device (RCD), turns the power off in a fraction of a second when it detects electricity leaking to earth at a harmful level, typically 30 milliamps or less. That is fast enough to prevent a fatal electric shock, and safety switches have greatly reduced injuries and deaths from electrocution.

Can I install a safety switch myself?

Safety switches can only be installed by a licensed electrician. They can be retrofitted to almost any installation, either at the switchboard to protect every light and power circuit, or at a single power point. Ambient installs, repairs and tests them to Australian Standards. More on DIY electrical work in NSW.

How often should I test my safety switches?

The NSW Government recommends testing safety switches twice a year: press the TEST button on each one and it should switch off straight away. If it does not trip, it is not protecting you and needs replacing.

Will I get a compliance certificate when a safety switch is added?

Adding a safety switch alters the installation, so NSW law requires a compliance certificate (CCEW), lodged within 7 days, with a copy sent to you.

What affects the cost of adding safety switches?

The cost of adding safety switches depends on how many circuits need protection, whether the existing board has room for them, and whether an old board has to be replaced first. Peter checks the switchboard and gives you a clear quote before any work starts.

Why does my safety switch keep tripping?

A safety switch (RCD) trips when it detects electricity leaking to earth, usually through a faulty appliance, water in an outdoor fitting or damaged wiring.
