Is Your Home Missing Its Most Important Safety Device?

An RCD safety switch is the one thing standing between your family and a serious electric shock. It detects faults and cuts the power in a fraction of a second, faster than a heartbeat. But not all homes have them, and many that do are running outdated units that no longer meet current standards. CGF Electrical installs, upgrades and tests RCD safety switches across Sydney. Whether your board needs a single new unit or complete circuit protection, our residential electricians make sure your home is safe, compliant and properly covered.

An RCD (Residual Current Device) constantly monitors the flow of electricity through a circuit. If it detects current leaking to earth, such as through a person or faulty wiring, it shuts off power in under 0.03 seconds. That’s fast enough to save a life. A standard circuit breaker protects appliances and wiring from overloads. An RCD protects people from electric shock. You need both. Under AS/NZS 3000, RCD protection is now mandatory on all residential final sub circuits, including power points, lighting and wet areas. From 1 May 2023, Type AC RCDs can no longer be installed in Australia. Only Type A or Type B units meet current requirements.

Many older homes across Sydney still operate without proper safety switch protection.

You may need RCD installation or upgrades if:

  • Your switchboard still uses ceramic fuses – a switchboard upgrade is usually the best fix
  • You do not have safety switches installed
  • Circuits trip frequently – this often points to a fault our electrical repair team can trace
  • Your home has outdated wiring
  • You are renovating or upgrading appliances
  • Your switchboard has not been updated in years

If you’re unsure whether your home has adequate RCD protection, our electricians can inspect your switchboard and recommend the safest solution. Book an RCD inspection.
