or products called 'in-wall' are meaningless terms, at least in the US.We use 'Exposed' and 'Concealed' as installation enviroments, and 'Types' to define a wire construction; each of which has defined conditions of Exposed and Concealed installation methods (or prohibitions of installation.)
None of the 'in-wall' power I've seen are defined as US Types. The jps stuff appears - based on the metric dimensions - to be some euro imported stuff, twisted pair or triad based on the jacket appearance. Twisted pair AC wiring certainly has some appeal, but the rest of the vauge info on this product makes it a non-starter. Some props for at least specifying a voltage and temperature rating of the insulation on this stuff. Other products can't even do that.
All of these non-listed products would have to undergo testing per UL 719, Standard for Nonmetallic-Sheathed Cables, (since that is what they are.) They would be evaluated and tested for flammability, dielectric voltage-withstand, cold temp unwinding, pulling through joists, conductor pullout, and jacket abrasion resistance. Obviously, the life of NM cable on a residential install is not very tender.
So for good reason, Type NM cables per NEC 2005 are required to be Listed.
Everything you ever wanted to know about US building wiring types can be be found in ULs Wire and Cable Marking Guide.
