outdoor wiring question

| eag111@aol.com 2005-07-19, 12:26 pm |
| I want to run two lines from my basement to a second-floor bedroom. One
will be 12-2 non-metallic cable, the other cat 5 wire for an internet
connection. For part of the run, the wires will run along the outside
wall of the house. The run will be 10 feet horizontal, a 90-degree
turn, another 10 feet horizontal, a 90 degree turn, 10 feet vertical. I
want to enclose the wires...my question is, can I use pvc pipe? Or must
I use emt? and what size would be appropriate. Thanks!

PVC can be used outside when not subject to physical damage AND rated for
the installation.
I am not aware of any PVC that is rated to be exposed to the sun. There were
some companies that made 2 inch PVC risers for residential. I have not see
those for a long time.
If you live in sun country PVC even painted will not hold up for very long.
You do know that the cat 5 cable needs to have a 300 volt rated insulation
to be run in the same conduit.
The insulation on romex/ non-metallic cable is not rated for running in
conduit.
I am not sure if wire mold can be subjected to the elements. If it can it
might be a thought.

PVC electrical conduit. Half-inch trade size meets Code, but it'll be a XXXXX
pulling the Romex cable through. Go bigger: 3/4" or 1". There's not much cost
difference, and you'll be glad you did.
You need a separate conduit for the CAT5 cable. 1/2" will be fine there.[vbcol=seagreen]

PVC electrical conduit is. PVC water pipe is not.

You misspelled "can't be run in the same conduit".

False. Why you continue to say this, after your error has been pointed out to
you many times, is a mystery to me. There is *nothing* in the NEC that
prohibits use of NM cable in conduit.

Dry locations only.

Nonmetallic-Sheathed Cables
UL 719
1 Scope
1.1 These requirements cover nonmetallic-sheathed cables containing 2 - 4
thermoplastic-insulated circuit conductors with or without a grounding
conductor in the constructions indicated in Table 1.1. These cables are
intended for use in accordance with Article 334 and other applicable parts
of the National Electrical Code (NEC) , ANSI/NFPA 70. Type NMC cable is for
use in dry, moist, damp, and corrosive locations, and Type NM cable is for
use in normally dry locations. Both types carry the suffix letter "-B" to
designate the use of conductors with 90°C insulation.
The best part of the United States is the ability to speak your mind. Even
if you have a dissenting opinion.
Reading Article 334 I will concede that there is nothing that says NM, NMC,
or NMS and not be run in conduit. There are several references to dry,
moist , damp and other locations. There is nothing that says it can be
installed in a wet location. I consider outside a wet location.

Buy inside a terminated-on-both-ends conduit is a dry location...

Hi,
Instead of CAT 5, how about going wireless?
