Electricity is a powerful tool but it needs to be handled with care, especially at home. That's why we at Lake Road Electrical always recommend using residual current devices (RCDs) to keep your family safe from electrical shocks and fires.

What's an RCD? It's a safety device that quickly cuts off power if it detects a fault, like electricity flowing through a person or a wet appliance. This rapid response can prevent serious injuries, and even save lives.

How does an RCD work? An RCD monitors the electrical currents in the circuits it protects. If it detects any electricity leaking onto unintended paths, it shuts off the power immediately.

Types of RCDs

• Fixed RCDs: Installed in your switchboard. These protect multiple circuits throughout your home

• Socket-outlet RCDs: Built into outlets to protect specific areas or appliances.

• Portable RCDs: Useful for temporary setups, especially outdoors or in damp areas.

Costs

• Plug-in RCDs start at around $25

• Portable models are about $50

• Fixed RCDs are pricier but provide broader protection.

Testing Your RCDs 
Simply press the 'Test' button every three months. If it doesn’t trip or if you have concerns, it’s crucial to consult a professional.
