RCD Testing Brisbane
Ensure your safety switches are compliant and operating correctly
Residual Current Devices (RCDs), more commonly referred to as safety switches, are essential for electrical safety in both residential and commercial settings. These devices protect against electric shock and fire by quickly disconnecting power if they detect an imbalance in the electrical current. This imbalance often indicates that current is flowing through an unintended path—such as through water or a human body—which can be highly dangerous.
Why RCD Testing is Important
Sometimes referred to as “safety switch testing”, regular RCD testing is critical for workplaces to ensure compliance with legal requirements and enhance electrical safety.
RCDs can degrade over time due to environmental factors, wear, or electrical surges. Testing verifies that the RCD will trip within the required time frame to prevent serious injury or damage.

What Does the RCD Testing Process Involve?
RCD testing is typically conducted by licensed electricians or authorised technicians. They use specialised equipment to simulate fault conditions and verify the RCD’s response. The testing process involves checking the trip time, sensitivity, and overall performance of the device.
How Often is RCD Testing Required for Businesses?
The frequency of RCD testing depends on the type of business and its electrical environment. According to Australian WHS regulations and AS/NZS 3760 guidelines, commercial and industrial workplaces generally need RCD testing every 6 to 12 months. High-risk environments, such as those exposed to moisture or mechanical damage, may require more frequent checks. Regular testing ensures devices will activate promptly in an emergency, providing peace of mind and safeguarding employees and visitors.
