Portable RCD Testing Canberra Sites Rely On for Safety
Confirming residual current devices trip correctly — because a safety switch that doesn't trip in time isn't doing its job, and you can't tell by looking at it.
What Is Portable RCD Testing?
Portable RCD testing checks that a residual current device — a safety switch — trips within the required time when it detects a current leak, protecting users from electric shock. We provide this across Canberra as part of test and tag compliance, testing portable RCDs used in commercial, industrial, corporate, and residential settings.
ACT PRO Services is a Canberra-based provider of data cabling and test and tag safety compliance services, supporting residential, commercial, corporate, and industrial clients across the ACT.
Why RCD testing matters for safety
An RCD is designed to cut power almost instantly if it detects current leaking somewhere it shouldn't — like through a person who's accidentally touched a live wire. This makes it one of the most important safety devices on a site, but it only works if it's actually functioning correctly, and a faulty RCD often shows no outward sign of the problem.
Portable RCDs used on construction sites and in workshops face particularly demanding conditions — dust, moisture, vibration, and rough handling all increase the chance of a fault developing over time.
How we test your portable RCDs
We test portable RCDs using calibrated test equipment that measures the exact trip time when a fault current is simulated, confirming not just that the RCD trips, but that it trips within the time required by AS/NZS 3760.
We also check the RCD's test button function. Any RCD that fails to trip within the required time is tagged out of service immediately, with the specific trip time recorded — not just a pass or fail note.
Frequently asked questions
Portable RCD testing checks that a residual current device trips within the required time when it detects a current leak, protecting users from electric shock — measured with calibrated equipment and documented against AS/NZS 3760.
It depends on the environment — construction sites typically need more frequent testing than standard offices due to harsher operating conditions. We can assess your portable RCDs and recommend the correct schedule.
Costs depend on the number of devices being tested and the site's risk category. We provide a free quote after understanding your equipment count and site details.
An RCD that fails to trip within the required time is tagged out of service immediately, since it can't be relied on to protect against electric shock — we record the specific trip time measured.
The test button provides a quick daily check that the mechanism moves, but it doesn't confirm the trip time meets AS/NZS 3760 requirements — full testing with calibrated equipment is needed for that.
