: F1 V$ C  \2 ?1 z* Y9.12.13.1 refers to the test conditions prescribed in 9.12.1 and states that the impedance Z1 shall
not be used.
9.12.1 refers to the conditions in 9.12.1 to 9.12.12.
" s4 b7 L' q; w. ^9.12.2 and 9.12.7.4 require the test circuits according to figures 5 to 9 together with impedance
Z2 to be used.
According to these figures the following inconsistency appears:

' N9 f9 o  w' FFor a two pole switch normally rated for 400 V, the rated residual making and breaking

Due to the fact that the purpose of this test is not to cover the special fault conditions in IT-systems,
the test voltage for this verification of the rated residual making and breaking capacity should be

IEC SC23E WG2 decided to correct the inconsistent test requirement in IEC 61008-1 (1996-12), subclause
