Get AS/NZS 3760 certified verification for heavy-duty machinery and leads across Sydney, Canberra, and Lithgow. We provide the technical expertise and the compliance reports—you keep your site moving.
Inspection, testing and tagging of plug-connected 3-Phase electrical equipment and leads used in industrial, commercial and construction environments.
AS/NZS 3760:2022, with AS/NZS 3012 requirements applying on construction and demolition sites.
3-phase equipment powers Australian industrial and commercial operations—from heavy machinery to HVAC systems. These high-power systems demand regular testing to prevent electric shock, equipment failure, and downtime.
Liberty Test & Tag provides certified 3-phase test and tag across Sydney, Canberra, and Lithgow, as part of our comprehensive test and tag services. We perform earth continuity and insulation resistance testing to AS/NZS 3760 standards—detecting faults before they become hazards, all while equipment remains de-energised.
Detect insulation faults and earth leakage before they pose electric shock risks to operators and maintenance staff.
Regular testing ensures your workplace meets Australian electrical safety standards and WHS obligations.
Identifying equipment faults early prevents unexpected failures that halt production and damage expensive machinery.
Documented testing demonstrates due diligence, protecting your business from WHS penalties and insurance claims.
Safe, systematic testing—accurate results using de-energised methods, with live testing available where required.
Check cables, plugs, and casings for damage, wear, or modifications.
Measure resistance from earth pin to exposed metal—verifies grounding integrity.
Test insulation integrity between conductors and earth with calibrated instruments.
Apply compliant tags and deliver pass/fail reports with retest dates.
Liberty Test & Tag performs 3-phase testing primarily in a de-energised, isolated state. This allows us to safely complete earth continuity and insulation resistance testing in line with AS/NZS 3760—without introducing unnecessary risk to personnel or operations.
Where appropriate, we energise equipment and measure leakage current while it is operating.
This allows us to:
All results are captured digitally, providing fully traceable, audit-ready records for higher-risk or critical equipment.
For most workplaces, de-energised testing is sufficient. Where a higher level of verification is required, live testing can be performed as part of a controlled testing process.
We test all 3-phase electrical equipment—portable leads to fixed industrial machinery.
Construction & Hostile Environments
Sites with heavy use, dust, moisture, or vibration
Workshops & Manufacturing
Regular industrial use in controlled environments

Stationary equipment in clean, dry conditions
3-phase testing falls under AS/NZS 3760:2022—the standard for in-service electrical safety testing. This mandates regular testing to identify faults before they cause incidents.
Regular 3-phase test and tag demonstrates WHS compliance. Documented testing proves you've met your legal duty to maintain safe electrical equipment, including RCD safety switch testing.
