If you read any of my posts on the use of CAT 5 you would know why. CAT 5 seems to have become the "universal" low voltage wire seemingly because of the "that's what I have" attitude not because it should be used.
Without beating a dead horse it all boils down to workmanship. I have seen doorbells, thermostats, speakers and God knows what else wired with CAT 5. If I see a run of CAT 5 I automatically WANT to assume that it is data run or possibly a telephone run and that's how it should be. The worst thing is to try to follow one of these runs and learn that everything else in the place was wired with the same wire.
