In Canberra and throughout Australia, Residual Current Device (RCD) Testing is a mandatory procedure under AS/NZS 3760:2022. This test confirms whether your safety switches trip properly in case an electrical fault occurs.
For 2026, electrical compliance rules for ACT workplaces are set out in AS/NZS 3760:2022. Retail stores, schools, and government offices need to ensure compliance to keep employees, clients, and visitors safe. It is a responsibility that demands careful consideration, especially when the safety of people is on the line.
What Is RCD Testing? A Safety Guide for Canberra Workplaces
RCD Testing is the process of checking Residual Current Devices to determine whether they are still fast enough to save lives during electrical mishaps. An RCD, also known as a “safety switch,” detects electrical current imbalances and trips within milliseconds to prevent electrocution and fires.
If there is an abnormal current, the RCD trips to shut off power immediately and avert disasters. With RCD Testing, you can monitor whether your RCDs need repair or replacement. This guide covers how RCDs work, and why testing is essential for workplace safety and compliance.
What Is RCD Testing and How Does It Improve Electrical Safety?
RCD Testing is the safest and government-regulated process to confirm an RCD's fitness for continued use. It involves using a specialised tester that simulates a short circuit to see if the RCD will trip when needed.
How RCDs keep business safe:
- They detect earth faults caused by water ingress or damaged wiring
- They trip instantly (usually 20-40 milliseconds) to minimise injury
- They guard both portable and fixed installations
The reaction time of RCDs is so quick that individuals nearby or interacting directly with dangerous electrical equipment will be protected.
What triggers RCDs to trip
The following are scenarios that trigger RCDs to trip:
- Overloaded circuit: too many appliances are drawing power from one circuit (e.g., overloaded extension cords)
- Short circuit: the exposed wire from a frayed cord touches another live wire, causing a spark or explosion
- Ground fault: electricity escapes the circuit after coming into contact with a damp material or bare skin
- Faulty appliance: an appliance draws too much power due to internal damage
Why Canberra Offices and Facilities Require RCD Testing
RCD Testing ties into overall electrical safety services and preparation. Here are the reasons why RCD Testing is required in Canberra:
- ensures legal compliance under AS/NZS 3760:2022 and relevant Australian laws
- prevents fatal electrocution
- prevents equipment damage or overheating
- detects hidden electrical faults
- ensures electrical safety over time
The RCD Testing Process Explained
The RCD Testing process involves:
- Performing a manual Push-Button Test to confirm immediate disconnection
- Using an RCD Tester to check the trip time
- Identifying and resolving faults, if there are any
- Updating the compliance register with results and the next due date
Under AS/NZS 3760:2022 Type 1 RCDs must trip within 40 milliseconds, and Type 2 RCDs should trip within 300 milliseconds. Otherwise, the RCD will be subject to replacement. Moreover, each step must be completed diligently to ensure that the safety switch can respond correctly.
The Role of RCD Testing in Test and Tag Compliance
RCD Testing plays an essential role in any compliant Test and Tag program. While Test and Tag focuses on the safety of portable electrical appliances (e.g., ovens, heaters, coffee machines), RCD Testing ensures safety switches will operate correctly in case these appliances become defective or dangerous.

Frequently Asked Questions
Is RCD Testing a legal requirement in Canberra?
Yes. RCD Testing is a legal requirement under ACT Work Health and Safety legislation. Businesses must ensure RCDs are installed, tested, and maintained in safe working conditions.
Do government buildings and offices in Canberra need RCD Testing?
Yes. RCDs in government buildings and offices in Canberra need testing to remain compliant with AS/NZS 3760:2022. Regular testing can help maintain an electrically safe workplace.
Does RCD Testing replace Test and Tag in Canberra?
No. RCD Testing does not replace Test and Tag in Canberra. Both services work together and should be done regularly to comply with Australian laws.
Key Takeaways
RCD Testing is an important aspect of safety compliance for Canberra workplaces. It can be done simultaneously or together with Test and Tag for maximum protection. RCDs keep workplaces safe by cutting off power in case electrical anomalies occur.
If the RCD is damaged or faulty, it will not trip, causing the current to continue flowing. Any person touching a live wire could potentially perish from electrocution, or a fire could be ignited by exposed live wires.
Working with a trusted RCD Testing team in Canberra will help you prevent electrical mishaps. Are you ready to take the next step towards a safe and fully compliant workplace? Choose The Local Guys for dependable RCD Testing and enjoy peace of mind knowing your workplace is in expert hands.
