RCD Testing Perth (Safety Switch Compliance)
Professional residual current device testing for WA workplaces under the Electricity Regulations 1947, WHS Regulations 2022, and AS/NZS 3012. Compliance certificates issued within 48 hours.
WHAT IS AN RCD (residual current device)?
A residual current device (RCD) is a protective device installed in switchboards that continuously monitors current flow across a circuit. If it detects a leakage current (for example: electricity flowing through a person to ground) it cuts power in under 300 milliseconds.
RCD installation is mandatory on all hostile environment circuits in WA, and portable RCDs are required for all portable equipment at worksites under WorkSafe OHS Regulations 2022, Regulation 360. Having one installed is not enough. It must be regularly tested by a competent person to confirm it will function when needed.
WHAT IS RCD TESTING?
RCD (Residual Current Device) testing involved inspecting and verifying the functionality of RCDs to ensure they provide adequate protection against electric shock and fire caused by electrical faults. RCDs work by quickly disconnecting the power supply when they detect a leakage current, such as when electricity flows through a person to ground. Testing ensures that RCD’s operate correctly and that all associated compliance factors are met under WHS Regulations 2022.
Push-button functionality test
Verifies the RCD mechanism by simulating a fault. Depending on the environment, testing by a competent person is required every 3 or 6 months. During testing, board condition, access clearance, and the number of RCDs per breaker are also assessed for WHS Regulations 2022 compliance.
Operating time test
Measures the time taken for the RCD to trip under fault conditions using PAT testing equipment. This is a less common requirement, generally only applicable to portable RCDs or at the time of installation. Operating time testing is not required in most business settings.
Regulatory update — DEMIRS: Following recent changes by the Department of Energy, Mines, Industry Regulation and Safety (DEMIRS), injection testing and operating time testing at switchboards is no longer lawful in Western Australia. It is illegal for a licensed electrician or any other worker to remove escutcheon panels to complete injection testing.

WHAT DOES PTTS TEST?
Push-button functionality test
The integral test button is activated twice to confirm the RCD trips and resets, per AS 3019 clause 4.2.2.6. This is the legally recognised method for routine in-service testing in WA.
Switchboard visual inspection
Board condition, access clearance, and number of RCDs per breaker are assessed to confirm compliance with WHS Regulations 2022.
Portable RCD testing
Each portable RCD unit is tested individually for worksites relying on portable protection under Regulation 3.60.
Compliance documentation
Digital compliance report issued within 48 hours, listing each device, its result, and the next due date.
WHY PERTH BUSINESSES CHOOSE PTTS
RCD Testing Perth: Frequently Asked Questions
-
Yes, under WHS Regulations 2022, Regulation 165, any person with management or control of a WA workplace must ensure RCDs are tested regularly by a competent person. Failure to comply can result in WorkSafe penalties, voided insurance, and increased legal liability if an incident occurs.
-
Construction and demolition sites require testing every 3 months under AS/NZS 3012. Most commercial workplaces require 6-monthly testing under WHS Regulations 2022. Hotels and short-stay accommodation follow a 12 to 24 month cycle under AS/NZS 3760.
-
No, not for routine in-service testing. DEMIRS and Energy Safety WA have confirmed that removing switchboard escutcheons for injection or timed trip testing constitutes energised work under the Electricity (Licensing) Regulations 1991. See Energy Bulletin 78 for the full regulatory position.
-
A failed RCD must be taken out of service and repaired or replaced before the circuit is used again. PTTS flags all failed devices in your compliance report with recommended next steps.
-
Yes, in addition to full Perth metro coverage, PTTS services regional WA including the South West, Goldfields, Mid West, and Gascoyne regions. Contact us to discuss scheduling for your regional site.
