What is the purpose of an RCD?



As far as safety goes, electricity is one danger that you don’t want to leave up to chance. A safety switch(Also known as an RCD-Residual Current Device) is designed to activate and trip(turn off) the circuit if current leakage is detected, all in a fraction of a second. The purpose of a safety switch is to protect you, your loved ones and anybody visiting/working at your property or workplace from an electric shock which can potentially kill.

Safety switches will turn off when there is a faulty appliance, water in an electrical fitting, rodent’s chewed through cables or even something as simple as drilling a screw into a wall to hold your picture frame up that nicks a screw going in.

Remember- An RCD is designed to save lives, and it is vital to ensure they work in the event of an electrical incident!

If your appliance is faulty and your RCD does not trip within the required time, fatal and harmful injuries such as electric shock can occur. Regular safety switch testing can help you avoid dangerous occurrences in your home and business.

The Test Man can make sure your RCD is working efficiently, so you are protected if this type of electrical fault occurs. It is vital for every business to undertake RCD testing to ensure the safety of its staff members. RCD testing is prescribed in AS/NZS 3760:2010.

Our industry knowledge ensures you meet the correct safety standards in order to operate effectively as a business.

All residences and workplaces should have at least one safety switch installed even if it was years ago, as power circuits require one.

The rules have changed over the years, and the latest copy of the rulebook AS/NZS 3000:2018 has significant changes listed. If unsure if you have the required protection, seek advice from The Test Man to ensure you are up to the current standard.

Only the circuit that the safety switch is installed on will protect you, and instead of just being on the power circuit, you should consider having them installed on all individual circuits including lights, air-conditioning, oven, hot water and pool equipment circuits just to name a few.

In accordance with AS/NZS 3760:2010, RCD’s need to be regularly checked to ensure they respond to any fault as they are designed to do, within a certain time frame. Failing to trip in the required time, can be problematic and fatal if anybody is to receive an electric shock off the equipment or circuit.

WHS regulations also state that it is a requirement that all businesses have RCD’s protecting all hostile environments and it is a necessity to have the RCD’s tested in accordance with AS/NZS 3760:2010. This is known to be in date by leaving a test tag on the front of the board or somewhere easily visible.
