Ensure safety and compliance with professional testing for 3-phase leads and machinery.
3-phase equipment is the backbone of Australian industrial and commercial operations—from heavy manufacturing machinery to construction tools and large-scale HVAC systems. Unlike standard single-phase appliances, 3-phase equipment delivers higher power output, making it indispensable for demanding applications.
However, with great power comes greater risk. Insulation breakdown, damaged earth connections, and worn cables can lead to electric shock, equipment failure, and costly downtime. That's where professional 3-phase testing becomes vital.
Liberty Test & Tag provides comprehensive 3-phase test and tag services across Sydney, Canberra, and Lithgow. Our certified technicians perform thorough earth continuity testing and insulation resistance testing to detect faults before they become safety hazards—all while your equipment remains safely 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, and compliant—our proven process ensures accurate results without energising your equipment.
Examine cables, plugs, and equipment for visible damage, wear, or modifications before testing begins.
Measure resistance between earth pin and exposed metal to verify safe grounding pathways.
Test insulation integrity between live conductors and earth using calibrated instruments.
Apply compliant test tags and provide detailed pass/fail reports with next test due dates.
For maximum safety, Liberty Test & Tag performs all 3-phase testing with equipment de-energised and isolated. We test for earth continuity and insulation resistance—the two critical parameters that detect dangerous faults—without ever powering up your machinery.
This approach eliminates risk to our technicians and your equipment while providing comprehensive compliance testing under AS/NZS 3760 standards. Our calibrated test instruments deliver accurate, repeatable results that identify insulation breakdown, earth faults, and damaged cables before they cause incidents.
From portable leads to fixed industrial machinery, we test all types of 3-phase electrical equipment safely and efficiently.
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 equipment testing falls under AS/NZS 3760:2022—the Australian and New Zealand Standard for in-service safety inspection and testing of electrical equipment. This standard mandates regular testing to identify electrical faults before they cause workplace incidents.
Beyond technical compliance, regular 3-phase test and tag services demonstrate your commitment to Work Health and Safety (WHS) obligations. Employers have a legal duty to ensure electrical equipment is maintained in a safe condition—and documented testing is the best way to prove you've met this responsibility.
