RCD testing, or Residual Current Device testing, ensures that RCDs (safety switches) operate correctly to protect people from electric shock and electrical faults.
RCD trip time testing measures how quickly the device disconnects power in a fault condition, ensuring compliance with safety standards and protecting lives.
RCDs in workplaces should be tested every 6 months for operational checks and every 12 months for trip time testing as per AS/NZS 3760.
The acceptable trip time depends on the device type:
30mA RCDs: Must trip within 300ms at rated current.
High-sensitivity RCDs: Must trip faster (e.g., within 40ms at 150mA).
Only qualified personnel with proper equipment should perform RCD testing to ensure accurate results and compliance with safety regulations.
RCD testing requires specialised tools such as an RCD tester, which measures trip times and leakage current accurately.
A failed RCD must be replaced or repaired immediately. Our technicians provide detailed reports and recommendations for compliance.
Regular testing identifies faulty RCDs, ensuring they operate correctly during electrical faults, reducing the risk of electric shocks and fires.
Test and tag is the process of inspecting and testing electrical equipment to ensure it is safe to use. This involves a visual inspection followed by electrical testing, with compliant items tagged to indicate their safety status.
Regular testing and tagging help prevent electrical hazards, ensuring the safety of individuals and compliance with workplace health and safety regulations.
