Utp cable bundle with 14-2 ??
petem
I've seen on a post or on a web site last year a cable that was disgned for
home automation that had in the same cable a utp 4 piar cat 5e cable and a
14-2 cable for power...
anyone seen that somewhere ??
trying to find some so I could rewire part of my home..

I thought it was desirable to keep Cat 5 away from power cables, and only cross
at right angles.

There have been numerous attempts over the years to supply a 'strucutured
cabling' solution. In the end it's cheaper and actually easier to install
separate wires. Most of the time where the wires need to run isn't the same
place. Power goes to one place, network another, audio, etc. That and the
structured cables are far more bulky and more hassle to handle. Translating
into increased labor costs. Finally, terminating the cable often required
special connectors, adding more to the cost and labor expense. Thus running
regular wire, separately, ends up being a better solution.

Yes it is, but in this situation we are nor using it for ethernet...

Yup for audion and such having different cable passing as far away as
possible from 110 volt is the way to go.
But when its time to send signal that control automation module, passing the
wiring in one shot can be very usefull..

Eh, with proper insulation and connections it's possible. Trouble is that
'proper' aspect greatly raises the price.

How? By requiring larger holes and more difficult to pull cabling? And
then needing more expensive connectors on the end to properly split it out
to regular connections? And what if the long length of cable that was
pulled has a problem? You'd still have to go back and pull more wire. In
the end it's easier and cheaper (by a lot) to use separate cables.

Bill, we disagree on a lot of things, but you're 100% on the mark here.
Structured cable is an idea whose very short time has come and gone. It's
stiff, hard to manage, impossible to staple, requires larger holes, requires
much more time and bother if a segment fails and costs a hell of lot more
than uncombined cables. The only place I see it used now is in huge
installations where keeping associated wires together outweighs all the many
deficits. Doesn't sound like it's the case here. While I might use it if I
got a spool for free, I would never specify it for a new project. It's
become so unpopular that it's probably possible to get structured cable for
less than combined cables simply because vendors want to clear their
inventory.
Even if the poster isn't sending Ethernet over the UTP, whatever he *is*
sending (multiplexed video comes to mind) is still subject to the same
problems that arise from running data cables too close to power ones. It
could be OK if he is running cable to CCTV cams, because the power supply
could be low voltage DC, and not likely to cause any interference problems.
Without knowing what the wire is being used for makes this a guessing game.
Maybe the OP can enlighten us.

Ah, good to know you're not wrong all the time... heh.
> Structured cable is an idea whose very short time has come and gone.
Yes, that's my impression as well. It seems like a good idea until actually
put into use.
> Maybe the OP can enlighten us.
It does help when follow ups get posted...

Sorry for the delay, got what I was looking for..
Received an email and was able to order the cable..
Look like its someone in the industry think that structured cabling and
power cable in the same package is not a bad idea..
Dont ask were I got it, its still under test and will beta test for them..

One problem is there is so much deliberate misinformation
(some people call it lying) on the part of the cable
industry.
A few days ago I got a request for tech support from one of
our online clients. He wanted to order riser cable for use
in a house. I asked why riser cable. Someone convinced him
it was safer and better than "ordinary" wire.
Well, riser cable is a code requirement in specific
environments but not in his situation. I explained that
it's not needed, will not benefit him and will cost several
times what "ordinary" cable does. He was adamant. Nothing
but the best.
We chatted for a while. He's a nice guy, determined to do
the best job he can. Nothing I said would convince him, yet
he did ask for tech support which me that implies he wants
advice from someone who knows what's needed.
Ah, well. I helped him understand some other stuff and let
him place the order online. I won't process an order over
the phone for you if I know it's wrong. You have to make
your own mistake. I haven't checked (I don't handle that
part of the office any more) but I assume he got what he
wanted.
This would never have happened if not for someone else
telling the gentleman he needed it. The same thing happens
every day with "structured" cable. Less than scrupulous
marketers tell less than expert clients that they will have
a better system because the cable is "special".
Look at the hype surrounding audio cable. People buy
speaker wire with names of semi-precious stones, arrows on
the jacket indicating which end points toward the speaker,
braided with strands varying gauge so all the frequencies
will get through.... faster.
OK, that's enough ranting from me for today. :^)
