answers to the above questions were not apparent.

Gee Whiz Jim,
I just learned one new thing and now you want to force me into cramming
more into a already full box.  Are you nuts!!!   :-)

I don't know the specific answers to your question.  Please elaborate
with answers.  While doing so, answer the following.

What type of wire ties are to be used in the installation of fire wire in
a plenum area??  Just found out that one during my investigation on the
stranded wire thing.

Smallest gauge wire here is 18awg, no 22awg listed, but there is
stranded stuff.
