RCDs, or safety switches, are a proven way to reduce your risk of electrical shock. All the power in your home runs through the switchboard, so is it vital to have Safety Switches (RCDs) installed and maintained.
Even though RCDs are readily available, effective, and affordable, many Australian homes lack safety switches.
Here, I’ll cover why RCDs are one of the most important ways to keep you and your family safe against electrical hazards.
Understanding RCDs and Safety Switches
An RCD is a safety measure that switches off electricity instantaneously if an electrical fault is detected.
RCDs, also known as residual current devices, monitor the electric current in circuits. RCDs cut electricity within milliseconds if electricity is flowing where it shouldn’t.
This provides significant protection against electrical fires, electrocution, and electric shock.
I often have customers ask me about the difference between an RCD and a circuit breaker. Many people view circuit breakers and RCDs as interchangeable but these safety devices serve different purposes.
Here is a simple way i like to describe the different between RCDs and circuit breakers:
- RCDs — Designed to protect people against electrocution
- Circuit Breakers — Designed to protect electrical cables and appliances
Why RCDs Are Essential for Home Safety
Electrical faults can lead to electrocution, electrical fires, and other serious hazards. RCDs are a proven way to prevent potentially fatal accidents, such as electrical fires or electric shock.
RCDs are especially important in wet areas, such as kitchens, bathrooms, and laundry rooms.
Without RCD protection, a malfunctioning appliance may go unnoticed until it is too late and a shock occurs. If a person comes into contact with this electricity, it can be fatal.
Safety switches work by detecting current leaking from a circuit to the earth. By stopping the current within milliseconds, it significantly reduced a person’s risk of death or serious injury.
Unfortunately, around 15 Australians lose their lives every year in electrical accidents that could have been prevented by safety switches.
Even though RCD safety switches are readily available and legally required, many Australian homes do not have them.
This may be a result of confusion between RCDs and circuit breakers. Many homeowners mistakenly believe circuit breakers provide adequate protection against electrical hazards.
Our mission at Limelight Electrix is to educate homeowners on the immense importance of RCD safety switches.
If your home does not have RCD safety switches or you are unsure if your safety switches are working, contact a licensed electrician immediately.
Western Australian Regulations for RCDs
Because of the crucial protection and safety they provide, RCDs are legally required in Western Australia.
WA’s Department of Energy, Mines, Industry Regulation, and Safety states “all residential premises to be sold, rented or hired must have at least two RCDs protecting the final sub-circuits to socket outlets and lighting”.
A lot of my customers ask if they still need RCDs even if their home has circuit breakers. The answer? Absolutely.
You are still required to have a minimum of two RCDs even if your home already has circuit breakers.
Remember, safety switches protect people while circuit breakers protect things.
Circuit breakers can prevent short circuits and overloading but they do not offer protection against electrocution.
Residual current devices (RCDs) are more sensitive and effective than circuit breakers in preventing electrocutions and electrical fires.
RCDs provide protection against electrocution, which is why WA homes are required to have at least two safety switches.
Although two RCD switches are the minimum requirement, your home may need more. A licensed electrician contraction can determine exactly how many RCD safety switches you need for adequate protection.
Failing to comply with WA’s RCD regulations can result in penalties and fines. Failing to install at least two RCDs in your home also puts you at risk of potentially fatal electrical hazards.
How Often Should RCDs Be Tested or Replaced?
RCD protection is a proven way to reduce the risk of electrical shock, electrical fires, and other hazards. However, your RCD safety switches must be in good working condition to perform properly.
RCD testing and maintenance is imperative to ensure you are sufficiently protected. If an RCD cannot trip, damage can occur over time and put your home at risk of electrical hazards.
WA’s Department of Energy, Mines, Industry Regulation, and Safety recommends these steps to RCD testing:
- Check your safety switch according to the manufacturer’s instructions or once every three months (whichever is more frequent)
- *Portable RCDS should be tested every time they are used or in accordance with the manufacturer’s instructions
- If your metre box is in good condition, open it and press the “Test” button on each RCD (To find the test button, look for the “T”)
- The switch should immediately flip to the “OFF” position
- Flip the switch back on to reset it
If you notice any issues during the RCD testing process, contact a licensed electrician right away.
If you are not confident performing the testing on your own, enlist the help of a licensed electrician.
RCD switches should be replaced in the event of damage or faulty wiring. I recommend having your RCD switches professionally inspected and maintained on an annual basis. A professional wiring check should be scheduled at least once a decade.
Choosing the Right RCDs for Your Home
RCD safety switches come in a variety of types and ratings. When choosing the right RCDs for your home, it is important to make sure the RCD is compatible with your circuit.
When selecting an RCD type for your home, consider:
- Type of supply
- RCD voltage rating
- Application
- Frequency range
- Current rating
If you need help choosing the right RCDs for your home, our team is glad to help. We know it can be confusing sorting through all the types of RCDs. We can help you select the proper type and capacity that is compatible with your circuit.
Since RCD safety switches are powered by mains electricity, they must be installed by a licensed electrician.
