8.2.5 Earth leakage current test

This test measures the current leakage flowing from the mains part through or across the
insulation into the protective earth conductor of the device under test.
Perform this test both in Normal Condition (NC) and in a Single Fault Condition (SFC), where one
of the supply conductors is open at a time. Perform the test with normal and reverse polarity.
NOTE: Refer to the instructions delivered with the safety analyzer to perform this test.
NOTE: *The measuring device (MD) represents the network and voltage measuring instrument
and its frequency characters according to IEC 60601-1.
