At Southern Cross Electrics & Air Conditioning, we provide professional RCD Injection Time Testing to ensure your safety switches are operating correctly and providing the level of protection required under Australian Standards.
Residual Current Devices (RCDs) are critical safety components designed to instantly disconnect power when a fault or electrical leakage is detected. Our specialised testing verifies that each RCD trips within the required time limits, helping protect your staff, customers and property from electric shock and electrical hazards.
RCDs are designed to respond in milliseconds when a fault occurs, but over time they can become slow, unreliable or fail completely without any visible signs.
RCD Injection Time Testing confirms:
Correct trip time performance
Proper operation under fault conditions
Compliance with Australian Standards and WHS requirements
Protection against electric shock and electrical faults
Reliability of your electrical safety systems
This testing goes beyond simple push-button checks by using calibrated equipment to simulate fault conditions and measure actual response times.
Regular RCD testing is essential for maintaining a safe working environment and meeting regulatory and insurance obligations.
Routine testing helps you:
Reduce the risk of serious injury or electrocution
Identify faulty or non-compliant RCDs
Meet workplace safety and audit requirements
Maintain electrical system reliability
Avoid potential liability and compliance issues
Ensuring your RCDs function correctly is one of the most important steps in protecting people from electrical hazards.
Our RCD Injection Time Testing service includes:
Main switchboard RCDs
Circuit protection RCDs
Safety switches for power and lighting circuits
Commercial and industrial installations
Three-phase and single-phase systems
Testing is completed efficiently with minimal disruption to your operations.
After testing, you’ll receive a clear compliance report outlining:
RCD trip times and performance results
Identification of any faulty or non-compliant devices
Recommended corrective actions where required
Documentation for audits, insurance and safety records
We can also establish a scheduled testing program to ensure your RCDs remain compliant and your workplace stays protected year-round.
We provide RCD testing services for a wide range of industries, including offices and commercial buildings, retail stores and shopping centres, hospitality venues and commercial kitchens, medical and healthcare facilities, schools and childcare centres, industrial and manufacturing sites, construction and trade businesses, and tourism and accommodation providers.
