No, although it seems that there is an unofficial color code for romex
jackets in use nowadays. 14/2 is generally white and 12/2 is generally
yellow. this just makes it less likely for an installer to grab the
wrong spool of wire when working fast.
In my house, however, I have at least one run of 14/2 with a blue jacket
(which I think is now generally used for 10/2?) and one run of 12/2 with
a black jacket. Since there's no OFFICIAL color code the mfgr. can make
it any color they want.
replace "fly" with "com" to reply.
I was at home depot the other day and noticed rolls of 14/2 that had blue
jacketing. i asked the fellow what it was for and he says a code is being
proposed that blue wire be used for circuts on arc fault breakers like for
bedroom outlets so it is easy to distinguish for the inspector.
Had not heard that one. Since the 2008 code will require AFCI on all
15 and 20a circuits I doubt it will really catch on.
The Southwire (newest owners of the "Romex" name) uses the standard
Black 8ga or larger
Grey SE cable
Other manufacturers are somewhat following the lead but it has no
force of law.
That's what I'm hearing but I don't see how that will really catch on.
Certainly in many cases it will be impossible to retrofit older
buildings to meet code as there won't be enough space in the breaker
panel (AFCIs are full height, haven't seen any half height ones.)

Code applies only to new work. Retrofit of existing installations that met
Code when they were installed is not required, unless they're being modified.
Then the modified installation has to meet Code. But if it's left alone, no
retrofit is needed.

Hmm, I'm wiring my new house right now, I wonder if I should use more arc
faults on the receptacle circuits? I understand they are not good to use on
circuits serving lighting as per Rex Caldwell's Electrical book. They are
much more expensive that a regular breaker.

They are also looking at that. CMP2 stopped short of requiring AFCI in
any existing building that had a panel changed but they looked at it.
There is another way to go if you really want AFCIs, You can put them
in a sub panel or you can use a "device type" in a box if the box is
connected by a steel wiring method to the panel. (steel AC cable, RMC,
IMC EMT). Currently that has to be 6' or less but that is being
extended "to the first box".
True, but there are some people (like me) who actively try to
incorporate some of the better ideas of code into their house even
though they don't have to. e.g. since I am adding grounds to
receptacles, I might as well try to provide the now-required 20A
circuits for the kitchen and bath, and I've already added an AFCI for
the upstairs circuit simply because it was relatively easy to do and
now it meets code. I may not end up with a 100% code-compliant (for
new construction, that is) system, but it will be closer to it than I'm
required to make it.

ALL romex was white. I must admit, I am glad they colored it. As I
age it's getting harder and harder to read the print on the cables.
This makes it easy to ID the gauge.
