THE HIDDEN DANGER IN YOUR SWITCHBOARD
When it comes to electrical safety in the home, it’s often the hidden hazards that pose the greatest risks. One of the most overlooked — yet essential — safety mechanisms in any Western Australian home is the Residual Current Device (RCD). Without proper RCD protection, your family, property, or tenants could be exposed to life-threatening electrical faults.
What Is an RCD and Why Is It So Important?
An RCD (Residual Current Device) is a life-saving switch that constantly monitors the flow of electricity in a circuit. If it detects even the slightest leak of current — for example, from a damaged cable, a faulty appliance, or moisture getting into a fitting — it will shut off power in as little as 30 milliseconds.
That split-second response can mean the difference between a harmless interruption and a deadly electric shock or house fire.
RCDs are usually located in your switchboard and are marked with a “T” or “Test” button. By law, every residential property in Western Australia must have at least two RCDs protecting all lighting and power circuits.
What Can Go Wrong Without RCD Protection?
If your switchboard doesn’t have RCDs, or they’re not functioning properly, electrical faults can go undetected — and the results can be devastating:
⚡ Electric Shocks
Simple tasks like plugging in a phone charger or flicking a light switch could expose you or your family to dangerous levels of current.🔥 Fire Hazards
Faulty or outdated wiring without RCD protection can overheat, causing electrical fires — a common risk in older Perth homes.⚖️ Legal & Financial Risk
For landlords and property managers, failing to comply with WA’s electrical safety regulations can result in fines and liability in the event of an accident.
Not Sure If Your Home Is Compliant?
