RCD Check
Protect Your Home & Business

A Residual Current Device (RCD) safety switch is a lifesaving electrical component that instantly cuts power when it detects a fault, preventing electric shocks, fires, and serious injuries. In Western Australia, RCDs are legally required in all homes and rental properties to ensure safety and compliance. At Voltaic Electrical, we provide professional RCD installation, testing, and upgrades across Perth, ensuring your property meets modern safety standards.
No RCD Puts Lives & Property at Risk
Without an RCD safety switch, faulty wiring, electrical surges, or damaged appliances can cause dangerous electric shocks, fires, or fatal accidents. Older properties often lack RCD protection, leaving residents at risk.
Common dangers of not having an RCD safety switch include:
- High Risk of Electric Shock
If a live wire is touched, an RCD shuts off power within milliseconds, preventing injury or electrocution. - Increased Fire Hazards
Faulty appliances, overloaded circuits, or wiring issues can spark fires without an RCD’s automatic cut-off. - Unprotected Circuits
Many older switchboards rely on outdated fuses that do not provide personal protection like RCDs. - Electrical Faults Going Undetected
An RCD picks up even minor electrical leaks, helping prevent major faults before they escalate. - Landlords & Businesses Failing Safety Standards
Rental properties and workplaces must have RCD protection to meet legal safety requirements. - Non-Compliance with WA Regulations
Western Australian law requires at least two RCDs in homes; failing to install them can result in fines and penalties.
Installing RCDs ensures your home or business is protected from electrical hazards, reducing the risk of injury, fire, and power failures.
