RCD Switches Explained

Residual Current Devices (RCD) Safety Switches are important safety devices which are installed in many Sydney homes that protect its occupants from dangerous electrocution situations. These small switches are crucial for the health and safety of your home and are relatively low in cost to install. The Local Electrician has over 25 years of experience in Sydney’s electrical field and are experts in RCD installation. As from the year 2000 and the Residual current devices – SafeWork NSW legislation, these devices are now compulsory to be installed into new homes and we highly encourage installing them into a home if it was built before 2000. Your local emergency electrician is qualified to properly and safely install a RCD.

RCD switches are designed to stop extreme electrical strikes and problems from damaging homes. From the year 2000, they are now compulsory to to install in switchboards. They work by quickly cutting-off the issue as they constantly monitor the current electrical flow in both the active and neutral wires. When an imbalance of the current flow happens in the wires, the RCD will shut down the power. This prevents damage to the building’s appliances and potential injury from electrocution.

3. Portable RCD Switches

These are designed for electrical tools and appliances that are not connected to a power meter or powerpoint RCD. They are attached to either an extension lead/cord or a power board which the electrical device can be connected to. As a result, the circuits are protected and are really important for those who use power tools or any electrical device outside of their home. However, they only protect appliances that are connected to them.

Important RCD Switches Considerations

There are a number of different actions a person should take to ensure that their RCD switch is correct, present and working.

Is a RCD switch installed in my home?

It is likely that a RCD Switch is installed if the home has been built after the year 2000. However, as it was not compulsory back then, not many houses installed RCD switches into the property before the year 2000. If there is uncertainty whether there is or not one in the property, call an electrician to perform an electrical safety inspection on the building. This is to identify if a RCD, and a proper one, is within the building. RCD switches are now mandatory to be installed in  all final sub circuits in a domestic installation.

How can I test to see if my RCD is working?

A qualified electrician will be able to undergo specific tests and methods to ensure that the RCD installed in the house is working correctly. We recommend that every three months is the safest option, pressing the “test” button. With this, a test will occur, and if the RCD is not working correctly it will indicate with signals. Therefore, this is when an electrician is strongly advised to be called out and to guarantee that the home is safe.

RCD Switch Testing

Testing to see if the RCD switches are working and have no faults is extremely important, particular during the warmer summer months. Knowing that the switches are providing constant protection is seen from RCD testing. The testing process of RCD switches detects faults early and prevents costly future electrical damages and potential fires.

Testing of RCD switches is especially important for appliances which plug into an outlet. This should be done for systems where the environment might negatively impact them. This includes rust, moisture levels, heat, corrosive chemicals, mechanical damage, rust and more. To follow safety standards here is how often RCD switches should be tested:

  • In residential properties (including hotels) RCDs are encouraged to be tested every 3 – 12 months
  • Industrial areas should be tested every 12 months
  • Environments which could impact the RCD switch in a negative way should have them tested every 6 months (e.g beaches, desserts, factories etc.)
  • When portable RCD switches are used they should be tested every 3 months
  • All tasks involving an RCD, such as installations, should be tested immediately after the service

How Do I Test My Homes RCD Switches?

  1. Before you test an RCD, shut down all your household’s electronic equipment
  2. Go to your switchboard and identify your RCD switch
  3. Push your test button down quickly (do not hold)
  4. You will hear a crunch sound and see your RCD flick to an off position, indicating that your switch has been turned off
  5. Check your household’s appliances to see if any are still on. If they are, this is a strong sign that your house may have faulty wiring and you will need to contact an electrician.
  6. Once you have finished testing, go back to your switchboard and turn your RCD back on by flicking the off switch to the on position
