Electrical Equipment

AS/NZS 3760:2010 – “In-Service Safety Inspection and Testing of Electrical Equipment” specifies the safety inspection and testing of low voltage single phase and polyphase electrical equipment, connected to the electrical supply by a flexible cord or connecting device.

The standard does not apply to fixed or stationary equipment that is connected to wiring that forms part of the electrical installation (i.e. hard-wired), or equipment that is installed at a height of 2.5 m or greater above the ground, where there is not a reasonable chance of a person touching the equipment and, at the same time, coming into contact with earth or any conducting medium through which a circuit may be completed to earth.

When applicable, in-service inspection and testing include:

  • Visual Inspection - External inspection of the equipment and connecting facilities (e.g. supply cord).
  • Earth Continuity Test - Protective Earth Continuity tests to Class I equipment, EPODs, cord sets, and cord extension sets.
  • Insulation Resistance Test OR Leakage Current Test - Insulation testing by measuring insulation resistance or leakage current.
  • Polarity Testing - Confirmation of the correct polarity of live connections in cord sets with rewireable plugs or rewireable connectors, and cord extension sets with rewireable plugs or rewireable cord extension sockets.

What is the process?

The “Test and Tag” process is made up of four main steps:

  1. Visual Inspection
    During the Test and Tag process, 90% of defects are detected via visual inspection.
  2. Testing
    The purpose of testing is to detect any unobservable electrical faults not found by the visual inspection process.
  3. Tagging
    The purpose of tagging electrical equipment is to provide easily identifiable visual evidence that the equipment has been checked and is safe to use.
  4. Reporting
    Once the inspection, test and tag process has been completed Jez Test and Tag provides a comprehensive Test Report that includes information about equipment details, what location/area within your workplace the equipment resides, who performed the tests, when the next test is due, and detailed test results (not just Pass/Fail).


Jez Test and Tag doesn’t only provide services in Geelong and surrounds, but also the Surf Coast through to Lorne, the Victorian Western District including Colac and Ballarat, and the Western suburbs of Melbourne.
