Portable electrical equipment, tools and flexible extension cords: construction siteBy: Licensed electrician, licensed electrical inspector, or competent person trained in pass/fail PAT testingState notesModel WHS jurisdictions (NSW, SA, TAS, ACT, NT, Cth; WA WHS (General) Regs 2022): r.163 makes AS/NZS 3012:2019 mandatory. QLD applies AS/NZS 3012 through the Electrical Safety Regulation 2013. VIC: the OHS Regulations 2017 contain no test-and-tag or RCD-testing regulation (no equivalent of model WHS r.150, r.163-165). The VIC benchmark is WorkSafe Victoria's Industry standard 'Electrical installations on construction sites' (Table 2); legal duty arises under OHS Act 2004 s.21 and OHS Regs r.114. VIC industry standard also requires 3-monthly test (earth continuity, insulation resistance per AS/NZS 3760). |

A planning guide, not legal advice. Intervals are minimums under normal conditions: shorten them where use, environment, damage or a risk assessment calls for it, and follow the current edition of the standard, your regulator's guidance and the manufacturer's instructions. Victoria operates under the Occupational Health and Safety Act 2004 and the OHS Regulations 2017; the other states and territories under the model WHS laws as adopted locally. Items checked 28 October 2026.
