IEC Lead Test

voltages are likely. This test can be omitted when testing equipment
with component whose voltage withstand rating is insufficient to
accommodate the test without damage. This is especially true of IT
equipment.

For Class I appliances, a nominal test voltage of 1.5kV AC RMS is
applied between the earth pin, and both the live and neutral pins of
the appliance mains supply plug

For Class II appliances, a nominal voltage of 3kV AC RMS is applied
between the flash probe tip and the live and neutral pins of the
appliance mains supply plug.

IEC Lead Test

Warning

250Vd.c. test voltage applied to lead depending on

hardware revision

If you are using hardware revision 1.23 or earlier then the IEC lead
test will be performed at 250Vdc. If you are using hardware revision
1.24 or later then the test will be performed at 40Vac.

This test confirms the electrical safety of 230V and 115V IEC leads.

The IEC test performs a continuity and polarity check on the Live and
Neutral conductors and confirming that there are no breaks or cross
wiring in these conductors.

Powered Tests

Warning

Mains voltage applied to appliance

The following powered tests differ from the previous tests in that they
apply mains supply voltage to the appliance to perform their
functions:-

• Leakage
