What is RCD Tagging?

RCD tagging refers to the process of testing and labelling Residual Current Devices (RCDs) to ensure they are functioning properly and in compliance with safety regulations. In Australia, RCDs play a vital role in protecting people from electric shock and preventing electrical fires by detecting earth leakage currents and switching off the power almost instantly. Tagging these devices after proper testing is an important step in workplace safety and is required under the AS/NZS 3760 standard.

RCDs are commonly found in commercial, industrial, and residential settings. They are especially important in environments where portable electrical equipment is used. The tagging process involves testing the RCD using a Portable Appliance Tester (PAT), confirming its trip time and current, and then attaching a tag that shows the date of the test, the name of the tester, and the next due test date. This ensures traceability and promotes a safe working environment.

Why RCD Testing and Tagging Matter

Regular RCD testing and tagging are essential for maintaining a compliant and secure electrical system. A faulty RCD can fail to protect people in the event of an electrical fault, which may lead to severe injury or even death. Therefore, testing intervals must be followed strictly as per the type of workplace and risk factors involved.

The RCD tag serves as visual proof that the device has been tested and is functioning as expected. Without proper tagging, businesses may fail to meet compliance requirements, which could result in penalties, insurance issues, or increased liability in the event of an accident.

Additionally, RCD tagging ensures business owners meet their duty of care under Work Health and Safety (WHS) regulations. Electrical maintenance, including RCD labelling, is not just a legal requirement — it’s a proactive step toward safeguarding employees, contractors, and visitors.

How RCD Tagging is Carried Out

The process of RCD tagging begins with a visual inspection of the device and its connections. Next, a qualified technician uses specialised testing equipment to verify the RCD’s response time and current threshold. These measurements confirm whether the device will disconnect power quickly enough in the event of an electrical fault.

If the RCD passes the test, a durable tag is attached. This tag typically includes:

• The date of the test

• The name or ID of the person who conducted the test

• The due date for the next test

• The test result (pass/fail)

For fixed RCDs, this tagging may be documented in a logbook or digital database rather than a physical tag, but the process remains similar. Portable RCDs and RCD-type power boards usually require visible tags.

Frequency of RCD Testing and Labelling

The frequency of RCD testing and tagging depends on the environment in which the devices operate. For example:

• Construction sites: RCDs must be tested every 3 months.

• Factories and workshops: Every 6 months.

• Office environments: Annually or every 2 years, depending on the equipment.

These timeframes are outlined in the AS/NZS 3760:2022 standard, which is the key reference document for electrical equipment maintenance and safety in Australia. Following these guidelines not only keeps workplaces safe but also demonstrates a commitment to best practices in risk management.

Benefits of RCD Tagging for Businesses

Investing in regular RCD tagging services offers a number of long-term benefits:

• Improved safety: Employees and visitors are better protected from electrical hazards.

• Regulatory compliance: Businesses meet WHS obligations and avoid potential fines or shutdowns.

• Peace of mind: Knowing all RCDs are functional gives employers confidence in their electrical systems.

• Efficient maintenance: RCD tags help keep track of testing history, making audits and inspections smoother.

By scheduling routine testing and tagging, businesses demonstrate responsibility and due diligence, which are valued in many industries.

Choosing a Reliable RCD Tagging Service

To ensure accuracy and compliance, it’s essential to work with qualified professionals who specialise in RCD testing and labelling. Look for providers who use calibrated testing equipment, follow the latest standards (such as AS/NZS 3760), and provide digital records of each inspection.

A good service provider will not only test and tag your RCDs but also explain the results, recommend follow-up actions if needed, and help set up reminders for future testing. Some also offer combined services that include electrical equipment test and tag, emergency light testing, and 3-phase appliance testing for full compliance coverage.

Common Mistakes to Avoid

When it comes to RCD tagging, a few common errors can compromise workplace safety:

• Skipping tests or testing too infrequently

• Illegible or incomplete tags

• Failing to update test records

• Using untrained personnel for testing

To avoid these issues, always rely on certified technicians and ensure your business has a reliable testing schedule in place. Remember, just because an RCD “looks fine” doesn’t mean it will function correctly during a fault.

RCD Tagging and Electrical Compliance

RCD tagging plays a central role in overall electrical compliance. It is often required during workplace inspections or WHS audits, and lacking proper records or valid tags can be a red flag. Whether your business operates in construction, retail, education, or hospitality, having a robust RCD testing and tagging system in place is critical.

By maintaining up-to-date RCD tags, businesses demonstrate their commitment to safety and legal compliance. This can also be beneficial when applying for certifications or tenders that require proof of safety practices.

In summary, RCD tagging is more than just a label — it’s a vital process that ensures your Residual Current Devices are ready to respond in the event of an electrical fault. Regular RCD testing and proper labelling help businesses stay compliant with Australian safety standards, avoid costly incidents, and protect the people who rely on their electrical systems every day.

Whether you’re managing a large industrial site or a small office, RCD tagging should be a priority. Don’t wait for an accident to take action — stay ahead with a proactive testing and tagging plan.
