RCD Testing
Residual Current Device testing and safety switch verification to protect your people.
Overview
What is RCD Testing?
Our RCD testing service verifies that your Residual Current Devices (safety switches) are functioning correctly and will protect your workers from electric shock. We perform push-button tests and operating time measurements per AS/NZS 3760. RCDs can disconnect power in as little as 30 milliseconds, and regular testing ensures they will activate when needed most.

Why It Matters
Why RCD Testing matters
RCDs can disconnect power in as little as 30 milliseconds — fast enough to save a life.
RCD testing is mandatory under WHS legislation for all Australian workplaces.
A faulty RCD gives a false sense of security while providing zero protection.
Regular testing is the only way to confirm an RCD will work when needed most.
Common Faults
What we commonly find
These are the most common faults found during rcd testing inspections in Perth workplaces.
Slow trip time
Risk: RCD disconnects too slowly to prevent electrocution.
RCD removed from service and replaced.
Failure to trip
Risk: RCD provides zero protection despite appearing functional.
RCD removed from service immediately.
Nuisance tripping
Risk: RCD trips during normal operation, causing disruption.
RCD tested and replaced if defective.
Incorrect wiring
Risk: RCD may not detect earth leakage correctly.
Wiring corrected and RCD retested.
Testing intervals
