Couple of things I need clarifying.
What is plenum rated cable? I worked in industry for years, but have been
retired for over 7, and never heard the term used. We used thhn and other
cables in cable trays and conduit.

Nor have I heard of any base T cabling. I use Cat5e used for a gigabit
netork and lots of it. Like many cables it has to meet a spec for handleing
signals.The mechanical quality of Cat5e cable varies widely. I have one
piece that has been just laying on the ground now for a couple of yerars
with no noticable deteoriation.

I have red, gray, and blue in the 1000' auto feed boxes. They all seem to do
well, but like most Cat5e cables they do not like short radius bends which
can make it a bit difficult to get into conduit.
