AS/NZS 3760 testing for industrial 3-phase equipment and leads.
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 without energising equipment.
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 tests all 3-phase equipment de-energised and isolated. We test earth continuity and insulation resistance—the two critical safety parameters—without powering up machinery.
This eliminates risk while providing comprehensive AS/NZS 3760 compliance. Our calibrated instruments deliver accurate results that identify faults before they cause incidents.
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
Fixed Installation & Offices
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.
