Wow,

I'm amazed and/or amused by some of the comments. Kofi nailed it - in all the places I've installed around the country the "Marked and Listed" was the most important issue for inspectors. Marked means that it has to have a rating listed on the outside jacket. Listed means that it must be tested by a recognized agency (often UL here in the states, but there are others). Until you are pulling wire in an MDU you will rarely ever need plenum wire.
