The Test & Tag Process

We carry out a comprehensive test regime on all mains-powered equipment connected by a flexible cord to a power outlet in accordance with AS/NZS 3760. This starts with a detailed visual inspection for visible defects that may compromise the safety of the appliance. This is followed by a sequence of electrical tests. The test sequence will vary according to the type of appliance, but fall into 3 main categories: Earth Circuit Integrity, Insulation Integrity and Polarity.

Earth Resistance

This test the ability of the earthing circuit of the appliance to carry fault current to earth. Double-Insulated appliances are not subject to this test. This can be either a Bond test or Screen test depending on the type of appliance.

Insulation Resistance

This tests ability of the insulation of the electrical conductors to prevent any current from "leaking" out of the wires. This usually involves, both a regular Insulation Resistance test and an Earth Leakage test.


This test confirms that the Active, Neutral and Earth conductors are correctly connected at each end of the power cord. This is usually only done on extension cords, detachable power supply cords (as used on computer equipment) and powerboards.
