The Double Insulation Test completes the following test sequences as part of its procedure
1. Integrated Supply Mains Test
Refer to Integrated Testsection
2. Integrated NCNT Test
Refer to Integrated Test section
3. Double Insulation Test (@250V or 500V): pass level greater
than 1MΩ
Procedure:
1.
Complete a Visual Inspection
(Note: Only proceed if test passed)
2.
Plug the appliance into appliance test socket.
3.
Connect earth clip to any exposed metal on the device (if any, or device can be wrapped in foil or use metal mesh

If the result was a fail - Tag with a
DANGER
tag and remove the device from service.
In some situations, if the device is labelled with “Surge Protection Fitted” or if it contains MOV’s (Metal Oxide Varistors),
conduct a 250V-insulation test. (Hint always read the compliance plates during Visual Mainly on surge protected
powerboards)
*If unsure always refer to the AS3760:2010 Standard.
Should it still fail, remove it from service. (Refer to the Technical Information section to change test voltage).
