RCD Testing Across Bunbury and the South-West
Trip-time and push-button testing of your RCD safety switches, logged against each board, for single and three-phase installations across the South-West.

What is RCD Testing?
RCD testing is the regular testing of your safety switches to make sure they trip fast enough to protect people from electric shock. RCD stands for Residual Current Device, the switch that cuts the power when it detects a fault.
It is carried out to AS/NZS 3760 and covers two checks: a push-button test that confirms the switch operates, and a trip-time test that measures how quickly it cuts the power.
A safety switch that does not trip in time is not doing its job. We test every RCD on your boards and log the result against each one.
What we test
- Switchboard-mounted RCDs and safety switches
- Portable RCDs and lead-mounted units
- Single and three-phase safety switches
- Push-button operation
- Measured trip time
- Results logged against each board
We test single and three-phase RCDs on every board and record each one, including four-wire and five-wire three-phase RCDs that many other operators do not have the equipment or technical knowledge to test properly.
Test and tag done properly, not rushed through
High Quality Testing
Both the push-button and the trip-time test to AS/NZS 3760, with the actual trip time measured and recorded, not just a click.
Single & Three-Phase
We test every RCD on your boards, single and three-phase. This includes four-wire and five-wire three-phase RCDs that many other operators do not have the equipment or technical knowledge to test properly.
Barcoded Reports
Every safety switch is logged against its board with its trip time and result, ready for your auditor.
Licensed Testers
Formally trained testers using calibrated equipment that is checked every year. Proper training, done right.
Affordable Pricing
Fair, competitive rates and a clear quote up front, with great value bundled with your test and tag.
Flexible Scheduling
We work around your site and your hours, and keep your RCD intervals lined up with your other testing.
Typical RCD testing intervals
| Test | Interval |
|---|---|
| Push-button test, fixed RCDs | 6 months |
| Trip-time test, fixed RCDs | 12 months |
| Push-button test, portable RCDs | 3 months |
| Construction and demolition | 3 months |
AS/NZS 3760 sets different intervals for the push-button test and the trip-time test, and the environment matters. We help you keep both on track.

We Test On Site
We push-button and trip-time test each RCD to AS/NZS 3760, and log the result against its board.
You Receive Your Report
You get a barcoded report showing every safety switch and its trip time, plus a reminder when the next test is due.
Credited in-depth reports
Every RCD test ends with a detailed, barcoded report. Each safety switch is logged against its board with its measured trip time and result.
It is built for asset tracking and WHS auditing, so you can show exactly which switches were tested, when, and how they performed.

Common questions about rcd testing
An RCD, or Residual Current Device, is the safety switch that cuts the power when it detects a fault, protecting people from electric shock. It only works if it trips fast enough, which is why it needs testing.
