Safety Switches & RCDs for Older Western Suburbs Homes
Many Wembley, Floreat and West Leederville homes were built before RCDs became mandatory. That old switchboard might have partial protection — or none at all. Safety switches save lives.
I retrofit proper RCD protection to older boards, or include it as part of a switchboard upgrade. All circuits covered, properly tested, compliant.

Pre-2000 Homes Often Lack Full RCD Protection
WA regulations have required RCDs on power circuits since 2000, and lighting circuits since 2009. Older homes may have none, or only partial coverage. A quick switchboard photo can tell you where you stand.
What Safety Switches Protect Against
RCDs detect current leaking where it shouldn't — through a person, water damage, or faulty wiring — and cut power in milliseconds.
Electric Shock
If you touch a live wire or faulty appliance, the RCD trips before you can be seriously hurt.
Faulty Appliances
Appliances with internal faults leak current — the RCD catches this before it becomes dangerous.
Water Ingress
Rain in outdoor power points, flooding, leaking pipes near wiring — RCDs detect the fault path.
Degraded Wiring
Old wiring with cracked insulation can leak current. RCDs provide a safety net.
DIY Gone Wrong
Accidentally drilling into a cable? The RCD trips instantly, limiting damage and injury.
Electrical Fires
Earth leakage faults can cause fires. RCDs cut power before heat builds up.
Types of Safety Switch Protection
Type I RCD (30mA)
Standard protection for power and lighting circuits. Trips at 30 milliamps — fast enough to prevent electrocution.
Type II RCD (30mA)
Similar protection level, different design. Commonly used in modern switchboard configurations.
RCBO (Combined)
Combines RCD and circuit breaker in one unit. Useful when retrofitting protection to individual circuits.

Safety Switch FAQs
What is an RCD / safety switch?
A Residual Current Device (RCD) monitors the flow of electricity and trips instantly if it detects current leaking through a person or fault. They save lives by cutting power in milliseconds — faster than a circuit breaker.
Does my home need safety switches?
In WA, all power and lighting circuits in homes built or renovated since 2000 require RCD protection. Many older western-suburbs homes have partial or no coverage. I can assess your switchboard and add protection where needed.
Why does my RCD keep tripping?
Common causes: faulty appliances, water ingress in outdoor circuits, degraded wiring in older homes, or an RCD that needs replacing. I can trace the fault systematically and fix the cause rather than just resetting it.
How long does RCD installation take?
Adding RCDs to an existing board typically takes 1-2 hours. If your board needs upgrading to fit modern RCDs, that adds time — I'll let you know after assessing your setup.
