RCD (Safety Switch) Testing SWMS
Safe Work Method Statement for periodic testing of residual current devices (safety switches) — push-button and operating-time testing, results, tags and records, replacement of failed RCDs after isolation, energised-work controls, switchboard access and planning power interruptions with building management.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
This Safe Work Method Statement covers periodic testing of residual current devices (safety switches) in New South Wales workplaces: push-button tests, operating-time (trip-time) tests with an RCD tester at socket outlets and switchboards, recording results, labelling and logbooks, and de-energised replacement of failed RCDs by a licensed electrician. It is written for electrical contractors and facilities maintenance businesses testing in commercial offices, retail premises, schools, government buildings, strata common areas and construction sites. It sets out who may do which test, the Part 4.7 requirements for energised testing (recorded risk assessment, authorisation, safety observer, suitable test equipment), isolation and test-before-touch for replacement, arc flash and shock controls, an asbestos register hold point for older switchboards, planning power interruptions around lifts, IT, refrigeration, life-safety and laboratory equipment, and a test record table, with controls in hierarchy order and inherent and residual risk ratings.
Hazards identified
10 hazards covered, sorted by priority.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — RCDs are replaced only with the circuit isolated, locked out and proven de-energised; testing is done at socket outlets with a plug-in adaptor where possible instead of removing switchboard covers; asbestos switchboard panels are not disturbed.
- 2Substitution — RCD testers with plug-in adaptors and automatic test sequences instead of open test leads; non-conductive platform ladders instead of step ladders.
- 3Isolation — Barriers and exclusion zones around open switchboards; only authorised persons in the immediate area; lock-out and danger tags for every worker during replacement; insulating mats and shrouds.
- 4Engineering — Test instruments rated Category III or IV with shrouded terminals and fused leads, properly tested and maintained; escutcheons refitted immediately.
- 5Administrative — Licensed electrician for instrument testing and replacement; recorded risk assessment and authorisation before energised testing; safety observer unless the assessment shows no serious risk for testing-only work; asbestos register check; written interruption plan agreed with the client; test records and labels; lone worker check-ins.
- 6PPE — Arc-rated clothing and face protection selected from the risk assessment, insulating gloves where live parts may be contacted, safety glasses and non-conductive safety footwear.
Applicable Codes of Practice
Inspecting and testing RCDs, competency, isolation and lock-out, testing for absence of voltage, energised electrical work, safety observers, test instruments and arc flash.
Platform ladders and step platforms for elevated distribution boards.
Asbestos register and presumed asbestos in older switchboards.
Awkward postures at switchboards and carrying instruments and ladders.
Consulting workers and coordinating interruptions with the client, building manager and other contractors.
First aid, CPR and AED arrangements for electrical work.
Only where the testing is construction work on a construction site.
High-Risk Construction Work triggered
Applies where the testing is construction work — for example testing RCDs on a construction site's electrical installation or as part of installing or altering an installation — and is carried out on or near energised installations.
Applies where the testing is construction work on a site where powered mobile plant moves near the site switchboards.
Construction work includes testing or maintenance of an essential service such as electricity (section 289(2)(e) of the Work Health and Safety Regulation 2025 (NSW)), but testing or maintenance work of a minor nature is excluded (section 289(3)(d)). Whether a particular testing job is minor is assessed job by job; where it is not construction work, sections 299 to 303 do not apply to it. Operating-time testing is still electrical work on energised equipment, and section 161 requires it to be carried out in accordance with a safe work method statement; this document is that statement. Where the testing is construction work and a section 291 paragraph applies, section 299 also applies, the work must be carried out in accordance with the SWMS (s300), and a copy goes to the principal contractor where the work is part of a construction project (s301). The document leaves the Applies column for the PCBU to complete for the actual site.

Worked example
An electrical contractor is engaged to carry out the periodic RCD test of a four-storey 1980s government office in Parramatta. Before the visit, the supervisor obtains the asbestos register, which records asbestos backing panels in two original distribution boards, and the facility manager's list of critical loads: the comms room, two lifts, the kitchen cool room and the security system. A written interruption plan sets an evening window, the lift contractor parks the lifts, and staff are notified. The licensed electrician records the risk assessment and the work is authorised. Push-button and operating-time tests are done at socket outlets with a plug-in adaptor where possible; at the asbestos boards the escutcheons are removed without disturbing the panels. One RCD trips at an excessive time: it is reported, the outlets it protects are taken out of use, and it is replaced de-energised after lock-out and a test for absence of voltage, then re-tested. Results go on the test record and the board logbooks, and the lifts and cool room are confirmed restored before the crew leaves.

Frequently asked questions
Is RCD testing high risk construction work?
It depends on the job. Testing of an essential service such as electricity is construction work (section 289(2)(e) of the Work Health and Safety Regulation 2025 (NSW)), but testing or maintenance work of a minor nature is excluded (section 289(3)(d)), so each testing job is assessed. It becomes high risk construction work under section 291(k) where the testing is construction work, such as on a construction site, and is carried out on or near energised installations. The document explains both cases.
Why do I need a SWMS if the work is not construction work?
Operating-time testing is electrical work on energised equipment. Section 161 of the Regulation requires that work to be carried out in accordance with a safe work method statement, by a competent person with suitable tested equipment, and with a safety observer unless the work is only testing and the risk assessment shows no serious risk. This document is written to be that statement.
Who can do the push-button test and who must do the trip-time test?
Under the document, a trained worker may press the test button where no cover is removed and no live part is exposed. Operating-time testing with an instrument, any test requiring a switchboard cover to be removed, and every RCD replacement are done by a licensed electrician.
Does it include a test record?
Yes. It includes a test record table for each RCD with the circuit, rating, push-button result, test current, trip time, pass or fail, tester and next test date, and explains the section 165 duty to keep records until the device is next tested or removed from use.
Is the document ready to use as supplied?
It is an editable Word template. You must add your business, licence, site, switchboard and instrument details, set the test intervals for the site environment from AS/NZS 3760, complete the high risk construction work table, and consult your workers before the work starts.
