RCD (Residual Current Device) Testing
What is an RCD?
An RCD is an acronym for Residual Current Device.
An RCD monitors the flow of electricity through the circuit it is attached to. Should any abnormalities associated with the delivery of an electric shock or fatal electrocution be detected by the RCD, the unit will shut off the power to the circuit immediately to minimise injury.
An RCD is a life saving device, but it does not completely eliminate the risk of electric shock. It must be tested to ensure it is working within the safety standards.
Does our “Safety Switch” (RCD) need regular testing and tagging?
Yes. Your RCD needs to be tested and tagged in accordance with AS/NZS 3760:2022 to ensure that it will respond in a fault situation, and that it will also respond within the required time frame. Should it not trip in the required time, a fatal and extensive electric shock may be delivered.
Additionally, WHS Regulations state all businesses must have a RCD protecting all hostile circuits, and that the RCDs must be tested in accordance with AS/NZS 3760:2022.
