A safety switch (RCD) cuts the power in a fraction of a second if current leaks to earth, which is what protects people from electric shock. Blue Link Electrical Services installs and tests safety switches across Sydney.
Many older homes have no safety switches, or only one covering part of the house. We check what you have and quote what is needed.
A circuit breaker or fuse protects the wiring from overload. A safety switch protects people. They do different jobs, and older boards often have only the first.
Under AS/NZS 3000, new and altered final subcircuits in homes need RCD protection rated at 30 mA or less. Older installations may have no RCDs at all.
Safety switches should be tested regularly with their test button. A switch that will not trip when tested, or trips constantly, needs attention.
The board may only have fuses or breakers.
One fault can then black out every circuit.
Usually a fault or a failing appliance.
The switch may have failed and needs replacing.
Good protection is part of a safe rental.
New circuits need RCD protection.
What protection you have and whether the board can take more.
RCDs or combined RCBOs, spread so one trip does not kill the whole house.
Circuits clearly labelled so you know what each switch covers.
Each device is tested for correct operation.
Safety switch installation must comply with AS/NZS 3000. New and altered final subcircuits in homes require RCD protection rated at 30 mA or less.
Where the switchboard is too old or full to take new devices, a switchboard upgrade may be needed first, and we explain why.
We would rather you read reviews where customers wrote them. Our Google Business Profile has reviews from customers across Sydney.
A circuit breaker protects the wiring from overload and short circuits. A safety switch (RCD) detects current leaking to earth and protects people from shock.
It depends on the number of circuits. Spreading circuits across several RCDs or using RCBOs means one fault does not black out the whole house.
Press the test button regularly, such as every three months. If it does not trip, call an electrician.
A faulty appliance, moisture or a wiring fault are the usual causes. Unplug appliances on the circuit and reset. If it trips again, call us.
