Howdy, Art.

I did the original UL evaluation on the Furukawa TEX and TEX-E wires.  I
just checked their web site

http://www.furukawa.co.jp/makisen/eng/safety/standard.htm#TEXE

and see that they make no claims regarding 61558-1.  The wire was
originally intended only for 950-type power supplies and that appears to
remain their primary market.
