Brian - Looks like it's a catch-all flag. It doesn't appear to be specific to any construction method or ANSI type. I did a search on OBMW2, modified by the keywords "Additional considerations." I found a mixture of information and noninformation. For some, the "thermal index is better than 200°C," was specifically cited, while others with 155 C ratings had the more generic statement, and still others that had 130 C, 155 C and 200 C wire types where the statement only applied top the 130 C and 155 C wire. Still another stated, "... because results of the evaluation of this magnet wire indicate a higher temperature classification than required for this ANSI type." I expect that the shortest route to finding out what the statement means in your specific case, is to have to talk to the manufacturer to get a copy of their Conditions of Acceptability for that magnet wire. If you wait for UL to say anything, it's a good bet that it'll be protected as proprietary and UL won't be able to say anything. Regards, Peter L.
