ETF3 and confirmed
by CTL at its 38th
meeting, in Toronto
Question:
" q5 `' J) c, }  b; k' uIt is stated that circuits exceeding 42.4V dc are not limited circuits. Since we assume, that
this value is not the intended one (because this value correspond with the peak value of
( p$ g" ]2 @0 D6.3.1.1) what is the common understanding of the Test Houses for a circuit with 50V dc?
Decision:
The values given in Annex F.2.1 should be in line with the values in sub-clause 6.3.1.1. It
was pointed out that values in Annex F.2.1 are typographical errors and should be corrected.
