It would probably be easier with 3/4 inch. They suggest pushing rather than
pulling Cat 5 cable through conduits but it can be pulled if you tape your
cable to your fishtape or wire every five to ten feet.
Isn't cat 5 about the size of coaxial ? My intention is to push/pull the
cable as I'm placing the conduit in the trench. So wouldn't 1/2" conduit do
the trick ?

The distance is about 150'. I'd like to use 20' sections but could use
It was suggested to me to use cat 5 because I want to have cable tv,
computer, phone and an intercom set up in the shop.
Will this type cable do the trick ?

Ray, Cat 5 wiring is an outdated standard which I would only recommend for
telephone. For residential high speed data lines Cat 6 is now the standard.
For cable TV you will need to pull a coax cable which I recommend RGB 6 Quad
Shield for optimum results. For intercom wire you must adhere to the
intercom manufacturer's specifications to get the best quality sound.
To get all this in one conduit, 1" would be the minimum size that I would
use though 11/4" would be an easier pull and allow for additional lines to
be added in the future.
Putting the wires in the conduit as you lay them in the ground is not an
efficient way to go. You will get dirt inside of the conduit, your wires
will be laying in the dirt and picking it up as you go along. It will be
very messy and worse if it rains while you are in the middle of this. You
will have a hard enough time keeping the conduit clean as you glue each
piece. You should also wait until the glue has fully cured before
installing any wires as it may affect the insulation of the wire. You may
find the wire getting glued to the conduit and you will no longer be able
pull it through any more.
My suggestion is to put all of the conduit in the ground first. This is
standard practice for professionals. Do not put more than 360 degrees worth
of bends in one run without a pull box or condulet. For easier pulling it
is recommended that you keep the total bends to 270 degrees per run.
To install the wire in the conduit get yourself some lightweight string and
a small lightweight bag such as the kind that you get from stores after a
purchase. You could also cut a piece of a plastic bag into a square and
make a little parachute by attaching a lightweight string to each corner.
You will also need a shop vacuum. Tie the string onto the handles of the
bag and put it into end of the pipe. Someone will have to feed the string
into the pipe as you go to the other end with the shop vac. Have the shop
vac on suction and put the hose over the end of the pipe and let it suck the
string through the pipe.
Once the string is out at the shop vac end connect a heavier pull rope to
the string and pull it into the conduit. Set up your spools or coils of
wire so that they can be unwound easy and without tangles. Spools can be
mounted on a steel conduit or rebar and hung between the steps of a ladder
to facilitate the pulling. Attach all of your wires onto the rope in a
tight compact manner. Put some pulling lubricant into the conduit and
continue to apply it as the wires are fed into the conduit. PVC conduit
seems to have more friction than metal conduit so be generous with the
Nah, but they're trying to get CAT-6 as the standard for new
installation. Spec says 200MHz, 1Gb bandwidth, but still a 100m maximum
Even if you don't attach premium networking products to the cable, or
use the bandwidth, the theory is it will be there when you (or the next
The residential network cable market is collapsing, though, as many
consumers turn to wireless ethernet -- generally 10Mbs, available in
100Mbps. Consumer media devices are starting to appear with built-in
wireless connectivity. It's hard to say whether that CAT6 will be needed
at all down the road.
Call me old fashion. I like my hardwiring. Reminds me of a technician
friend of mine. He took his new laptop computer outside to play around with
Windows XP while sitting on his patio. He accidentally got into his
neighbor's wireless network and was able to surf the web.
I use a wireless 10Mbs, with a DSL running at 1 meg, and never get
full speed when roaming the house, or lose connection altogether. I'm
also seriously considering pulling cat5 or 6 through the house. It
will not be easy for myself, the lower level has a sheetrocked
ceiling, and I'm not a experienced wire fish person, but will attempt
CAT5e is the standard which I would recommend. Its good for 10BaseT or
100BASE-T Ethernet and support up to 100 megabit per second data
transmission (100 MBPS). Currently I am working in a 7 story building
which is being built in a medical complex and all the computer
networking cable being installed is Cat5e.
