RCD – Residual Current Devices
Although Australia has one of the safest electrical systems in the world, accidents can still happen. A poorly maintained appliance, a person who innocently pushes something into a power socket or cuts through an electrical wire, a frayed cord, wet hands or carelessness with power tools are all situations that can lead to serious consequences.
The benefits of residual current devices (RCDs) are well documented and the latest version of wiring rules (AS/NZS 3000:2018) makes it mandatory to have RCD protection for all final sub-circuits in residential applications.
Amendment 2 of AS/NZS 3000:2018 makes it mandatory to have type A RCD (no type AC RCD) from May 2023 for additional safety. All RCDs under the MAX9 range are future-ready and already type A.
How an RCD works
The RCD works by constantly monitoring and comparing the current flow in both the Active and Neutral cables of an electrical installation.
During normal operation, these Active and Neutral currents are in balance. However, should any current flow to Earth, an imbalance is created in these circuits. If this imbalance is sufficient, the RCD will cut the electrical supply.
Apart from helping to protect people, RCD will also cut off power to expensive electrical equipment in the event of an electrical fault to Earth. This helps to protect appliances against costly damage and the installation against fire, resulting from faults of this nature.
Features and benefits:
