The Class 1- Earth Appliance Test completes the following 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. Earth Bond Test (@ 200mA): 200mA test current, pass level less than 1Ω
4. Insulation Test (@ 250V or 500V): pass level greater than 1MΩ
Please Note: 250V insulation testing applies to Class 1 appliances if selected (refer to Technical Information for details to
change test voltage)
In some situations, if the DUT is labelled with “Surge Protection Fitted” or if it contains MOV’s (Metal Oxide Varistors), conduct
a 250V-insulation test.
*If unsure refer to the AS3760 Standard. Should it still fail, remove it from service. (Refer to the Technical Information section
to change test voltage).
