Safety Switch (RCD/RCBO) Installation & Testing

A safety switch (RCD) cuts the power in a fraction of a second when it detects current leaking to earth – the kind of fault that causes electric shock and electrical fires. We install, upgrade and test safety switches and RCBOs for homes, units, rental properties, body corporates and businesses across Brisbane and South East Queensland.

Many older boards have no safety switches at all, or only one protecting the power points. If your board still has ceramic fuses or no room for extra devices, we’ll usually recommend a residential switchboard upgrade or a full switchboard replacement at the same time.

Why safety switches matter
  • Protect people from electric shock

    A safety switch monitors the current flowing in and out of a circuit. If some of it leaks to earth – through a faulty appliance, damaged cable or a person – it trips in around 30 milliseconds, fast enough to prevent a fatal shock.

  • Meet Queensland safety switch rules

    Queensland law requires safety switches in rental homes and, for older homes, when the property is sold. The rules were updated under the Electrical Safety Regulation 2026 – we will tell you what applies to your property and make sure it complies.

  • RCBOs stop one fault blacking out the house

    An RCBO combines a safety switch and circuit breaker for a single circuit, so a fault on the fridge or pool pump only trips that circuit – not every power point and light in the building.

Do you need new or extra safety switches?

  • Your switchboard has no safety switch, or only one covering the power points
  • Lighting, air conditioning, oven or hot water circuits are not protected
  • You are renting out or selling a home and need to meet Queensland safety switch rules
  • One fault trips the whole house – a sign more RCDs or RCBOs are needed
  • The test button doesn’t trip, or the switch hasn’t been tested in years
  • You’re adding solar, a battery, an EV charger or new circuits

Current wiring rules (AS/NZS 3000) require RCD protection on all final sub-circuits in homes when new work is done, so any renovation or switchboard change is a good time to bring protection up to date. Find out more about the switchboard upgrades we do across Brisbane.

    How a safety switch upgrade works

    • Step 1

      Inspection – we check the switchboard, which circuits are protected and whether the board has room for new RCDs or RCBOs.

    • Step 2

      Fixed quote – you get a clear price for the devices and any board changes before work starts.

    • Step 3

      Installation – most homes are done in a few hours with a short power-off period.

    • Step 4

      Testing and certificate – every device is trip-time tested and you receive a certificate of testing and compliance.

    • St Lucia unit sub-board upgrade with 14 safety switches

      An apartment owner in St Lucia needed a safer sub-board and a generator outlet after two floods left the unit without power for almost two weeks. We replaced the old board with a new 45-pole enclosure, upgraded all circuit protection with 14 safety switches and added a generator inlet.

    • Waverley home brought back to compliance

      This home’s switchboard no longer met Australian safety standards and was rejected by Energex for a new connection. We upgraded the board with new circuit protection and main earthing so it met current codes, with power fully restored within 24 hours.

    Safety switch (RCD/RCBO) FAQs

    Have more questions that aren’t answered here?

    Our friendly team are here to help out with any questions you might have.

    • What is the difference between an RCD and an RCBO?

      An RCD (residual current device) protects a group of circuits from earth leakage. An RCBO does the same job and also acts as the circuit breaker for one circuit, so a fault only trips that circuit. RCBOs take more room on the board but give the best protection with the least disruption.

    • How often should safety switches be tested?

      Press the test button at home every three months to make sure the switch trips. In rentals, body corporate common areas and workplaces, safety switches should also be trip-time tested by a licensed electrician on a regular schedule – we provide written test results for your records.

    • Why does my safety switch keep tripping?

      Usually because of a faulty appliance, moisture in an outdoor power point or light, or damaged wiring. Unplug everything and reset the switch, then plug items back in one at a time. If it still trips, or trips with nothing connected, call an electrician – don’t keep resetting it.

    • Do landlords in Queensland need safety switches?

      Yes. Owners of domestic rental properties in Queensland must have safety switches installed, and older homes need them when sold. The rules were updated under the Electrical Safety Regulation 2026 – we can check your property and bring it up to standard.

    • How much does it cost to install a safety switch?

      It depends on how many circuits need protection and whether your switchboard has room. Adding RCBOs to a modern board is quick; an old fuse board usually needs a switchboard upgrade first. After a free inspection we give you a fixed price.
