Saying "I don't go through return air conduits" sounds good in theory, but in a 2-story house it's nearly impossible to get cables from basement to top floor without using them. And as Adam said, even false ceilings count as plenum.
Personally I just use plenum-rated for everything as why stock more than one type, and there's no downside, except maybe it seems a bit stiffer. Cost really isn't a factor when you're just working on your house for a few runs, as it's your time that is the biggest "cost" for any cable work. (That's why I say always run CAT6 or better, too!) _______________________________________________ Roundtable mailing list -- roundtable@muug.ca To unsubscribe send an email to roundtable-leave@muug.ca
