BX is really an obsolete brand name. Usually that refers to AC cable
but it might also be MC cable or even conductors in flexible metalic
conduit by people who don't know better.
Conductors rated at 90c (temperature)
There is none in AC cable, the ground path is the armor and a bonding
Old style MC cable would have a 10ga insulated ground but the new MC
has an aluminum bonding wire larger than the conductors that is in
contact with the armor
This does not get extended into the box. The bonding is through the
connector like AC.
Now, if I were sitting at a computer connected to the Internet, I'd be
Googling for manufactdurer's catalogs - look at the Alcan web site,
BICC, and distributors like Anxiter and Texcan. I certainly wouldn't
put such a general inquiry on a newsgroup. When I was learning this
stuff I had to fill in reader service cards in magazines and wait for
the mail to come in - the Internet generation can find out *anything* in
There are also tons of training materials out there by the various
branches of the US Government - Navy manuals, Rural Electrification,
Department of Energy, and so on - there's a ton of fundamental
literature out there free for the downloading.
Sadly, current technology does not allow you to directly download .PDF
files into your head...you still have to read and understand.
