Why RCD Safety Switches Are Mandatory and How They Protect Your Home

What Is an RCD Safety Switch?

An RCD (Residual Current Device) is a life-saving safety switch that instantly cuts power when it detects a fault — like electricity leaking to the ground through a person or damaged appliance. It’s designed to prevent electrocution and fires, offering protection far beyond a standard circuit breaker.

🛠️ Why They’re Mandatory in Australia

Under Australian electrical safety laws, RCD switches are legally required in all new homes and electrical installations. For older homes, retrofitting RCDs is strongly advised — and often mandatory when selling, renting, or renovating.

✅ Key Requirements:

  • Must be installed on all power and lighting circuits.
  • Required in rental properties and new builds.
  • Compliance helps meet safety standards and protect insurance validity.

👨‍👩‍👧 How RCDs Protect Your Family

Whether it’s a child plugging in a device or a fault in an outdoor power point, RCDs are your first line of defence.

🚨 What They Prevent:

  • Electric shock from faulty appliances
  • Electrocution in wet areas like bathrooms
  • Fires caused by wiring faults or surges

They operate in milliseconds — often fast enough to prevent fatal injury.

🔍 How to Know If You Have RCD Protection

Look at your switchboard. RCDs are usually marked with a “T” button for testing. If your home doesn’t have them installed on every circuit, it’s time for an upgrade.
