Brilliant – thanks – I did always think that the correct table was as you showed in brief.

Kind regards

Neil – I had the same issue – you’re looking at a different issue of IEC 62368-1 (IEC 62368-1:2014, which is in our private area). IEC 62368-1:2018, Table 13 relates to Cable types, and is External circuit transiet voltages. It is Table 14 in the 2014 version:

Hi All,

I prefer George 1.

Sorry, I’m a little confused, maybe I missed something, however – I don’t see the connection to table 13 in IEC 62368-1?, which shows:

Kind regards

Hi George,

Thank you for providing the two text options for consideration.

My preference is to go with the George1 text.

Regards,

All – at the PDCC meeting, I took the action item to propose a rewrite of the statement below, so it did not require careful parsing of a comma to indicate that that the requirement referred to all external paired conductor cables with a diameter of 0.4mm:

Chad:

PSE circuits connected to external paired conductor cable, such as those described in Table 13 of IEC 62368-1, having a minimum wire diameter of 0,4 mm shall have the current limited to not more than 1,3 A.

I ended up with 2 versions, which I was arguing with myself over, and between Chad and Geoff they each preferred one or the other for the same reasons. Hence, please provide your insight &/or preference:

George1: this one goes for 2 shorter sentences, easier to parse for non-native speakers (or to translate); however, it is a bigger change in the actual text:

PSE circuits connected to external paired conductor cable having a minimum wire diameter of 0,4 mm shall have the current limited to not more than 1,3 A. Examples of such cables are described in Table 13 of IEC 62368-1.

George2: this one makes a smaller text change, just moving an existing clause within the sentence to avoid the comma-break. However, it is a complex sentence, more difficult to parse:

PSE circuits connected to external paired conductor cable having a minimum wire diameter of 0,4 mm, such as those described in Table 13 of IEC 62368-1, shall have the current limited to not more than 1,3 A.
