Protect your workplace from electric shock and fire with certified RCD testing. Our technicians ensure your residual current devices meet AS/NZS 3760 standards and function correctly when you need them most.
Residual Current Devices (RCDs), also known as safety switches, are your first line of defense against electric shock and electrical fires. An RCD monitors the flow of electricity and cuts power within milliseconds if it detects a fault—potentially saving lives.
However, RCDs can degrade over time without showing visible signs of failure. SafeWork NSW guidance recommends regular RCD testing to maintain electrical safety and ensure devices activate correctly.
An RCD can fail internally while still appearing to work normally. The test button on the device itself doesn't verify response time—only professional testing with calibrated equipment ensures your RCD will trip within the required 30 milliseconds during a real fault.
Examine switchboard and RCD condition, checking for damage, corrosion, or signs of overheating
Use calibrated RCD tester to measure exact trip time—must be under 30ms for 30mA devices
We record the measured trip time on the RCD tag (e.g., 18ms), giving operators immediate visibility of performance and ensuring clear, traceable results.
Learn how appliance test reporting works and why measured results matter in our detailed compliance guide.
Verify RCD trips at correct current threshold (typically 30mA for personnel protection)
