What is RCD Testing?
Residual Current Device (RCD) testing is a critical electrical safety procedure that checks whether safety switches in your property are functioning correctly. These life-saving devices protect against electric shocks and electrical fires by cutting off power within milliseconds when a fault is detected.
Why RCD Testing Matters in Australia
Australian law requires regular RCD testing under:
AS/NZS 3760
Work Health and Safety Regulations
Without proper testing, your business risks:
Electrical shock injuries or fatalities
Potential workplace lawsuits
Voided insurance claims
Heavy compliance fines
How RCD Testing Works
Our licensed technicians perform a comprehensive 3-stage test:
Push-button Test
Verifies mechanical operation
Checks trip time <300ms
Ramp Test
Gradually increases current to identify exact trip threshold
Must activate between 15-30mA
Trip Time Test
Measures how quickly the device cuts power
Must disconnect within 40ms at 5x rated current
Common RCD Failures We Find
Slow tripping times (over 40ms)
Failure to trip at correct current
Corroded contacts from moisture
Mechanical wear from age
Incorrect wiring during installation
