5.2.9 Touch leakage
This test determines the current that would flow if a person touches accessible conductive
parts of the DUT.
The instrument measures:
 The touch leakage current flowing through the S/EB probe into earth.
The DUT can be powered from the test socket or directly from the installation (fixed
installed equipment).
