RCD testing
What Is RCD Testing?
RCD testing checks whether each safety switch trips correctly under simulated fault conditions. Without regular testing, even a properly installed RCD may not operate fast enough to protect lives. Testing helps:
Prevent dangerous electric shocks and fires
Meet your workplace or rental property compliance requirements
Maintain insurance coverage in the event of an electrical fault
Our licensed electricians follow a multi-step process using professional-grade testing equipment:
Visual inspection
We assess each RCD and circuit for damage, correct wiring, and appropriate labelling.
Push-button test
Simulates a fault to verify the RCD trips when manually tested.
Trip-time test
Measures how quickly the RCD disconnects power (must trip within 300ms for a 30mA RCD).
Ramp test
Gradually increases fault current to confirm tripping sensitivity at the correct leakage threshold.
Documentation
You receive a detailed report showing test results, pass/fail status, and the next test due date

Frequently asked questions about RCD testing
What is RCD testing?
RCD testing checks that your safety switches trip correctly in a fault. It ensures they shut off power fast enough to prevent shocks or fires.
Why is RCD testing important?
RCDs can silently fail. Testing ensures they still work and keeps you compliant with Australian electrical safety standards.
How often should RCDs be tested?
In homes: every 12 months. In commercial properties: every 6 months. In high-risk sites: every 3 months or as per AS/NZS 3760.
Is RCD testing mandatory in Tasmania?
Yes, for workplaces, rentals, and commercial buildings under WHS and AS/NZS 3760. It’s strongly recommended for homeowners too.
Who can perform RCD testing?
Only licensed electricians or trained test technicians can carry out certified RCD testing under Australian standards.
Our team is:
Fully licensed by Tasmania’s electrical licensing board
Equipped with the latest fault simulation gear
Familiar with both residential and commercial switchboards
You get full documentation, including testing tags and compliance certificates for insurance or audit purposes.
How long does RCD testing take?
RCD testing usually takes 30–60 minutes depending on the number of devices. Each test takes a few seconds per switch.
What happens if an RCD fails the test?
It must be repaired or replaced immediately. A failed RCD won’t protect against electric shock or fire.
What types of RCDs need testing?
Fixed RCDs in switchboards, RCBOs, portable RCDs on tools, and safety switches built into outlets all need testing.
What does RCD testing involve?
We perform a visual inspection, a push-button test, trip-time test, and ramp test. You get a full compliance report.
Can I test my own RCD?
You can press the “Test” button monthly. But full RCD testing must be done by a licensed professional with proper equipment.
Do you provide documentation after testing?
Yes. You receive a compliance certificate, test tags, and a report listing trip times and pass/fail status.
