#423: voice and data in conduit? Author: noel, Location: Arkansas Posted: 23 Sep 2002 01:22 am
----
I was going to use a dbl gang box and run grey pvc conduit in the wall, up to the topplate, so I could run extra wires later, like speaker wires, or optic. would grey pvc help any in preventing interferrence from ac lines? would metal conduit?
Thanks

PVC would be of little protection from interference. EMT if grounded can be some protection from interference.
Be careful stuffing several communications and date lines in a conduit or you are back to interference again.
Maybe Don will pipe in with better ideas but that is what I am remembering.
If you are able to install conduit then why not just install pull strings with your original cables and not pack the communications and data lines in that conduit? The pull strings pulled through with your cables would give you an easy method of pulling additional lines in later on.
I would install separate boxes remodel style keeping distances from the different communications and date boxes if it were me.

sounds like you could run another conduit 6 inches away for another run.

There is arguments either way. pvc doesn't protect much in respect to shielding from interference, except to have the benifit of an easilier route in the future to add additional runs of wire. On the other hand metal can present another problem, if the specific length of conduit just happens to be the exact 1/4, 1/2 , 5/8 or full wave length of a well used transmit frequency of your local taxi company , or broadcast station, the metal conduit may prove to be an excellent receptor /antenna for that frequency and may under certain certainstances be picked up on your speaker wires going thru the conduit or other communciation /network type wiring.
kind of double edged sword.
Any kind of conduit will have the tendency to group all your wires close together, (the diamater of the inside of the conduit) , so you don't want wires too tightly packed together. It may take bigger holes to feed a conduit pipe thru walls or floor, as oposed to just feeding the cables thru. Be carefull not to weaken the studs with too big of holes. And don't have communication wires close to electrical.

Don is that why I have heard some way out people running around with aluminum foil all over their bodies so that they can't be a human anttenae, or were they doing that to become a human antennae or again were they just way out type people. While I agree with your discription of the attenae created if a metal conduit length is perfect match [by the way your are right in what you said] it was a bit fun reading your discription. Reminded me of science fiction movie or ghost stories of the past that tend to have some truth ringing true in the future of today. Kind of erie isn't it? Remember Star Trek with the flip open communicaters to their space ship? Think of the flip open mobile phones we use today. Seems our imagination of our youth and jumped up and become reality in our inventions of today. Fun anyway.
Just having some fun remembering wild stories of the past that now are reality or soon will be reality. Seems our world technology is limited only to our imagination as we think it.
