I’ve got to run some structured wiring from my house to my detached garage. I also need to feed my electrical subpanel as well. And since I’m digging a trench for the subpanel feed can I just put my cat5e in the same trench. They would both be running parallel for about 40 feet.
Thanks in advance.

Same ditch, but separate conduit. Or direct burial on one or the other, but conduit is better.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
with at least 6" of seperation between the conduets....

WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
The house is on a slab and I've only got one 2" pvc "sleeve" going through the slab to the outside. Would it be ok to run them in that same pvc pipe for the 3' til I get outside and then put them in different conduit?
can ya put the Cat line down the outside of the house into yur trench and drive on from there????
1/2" pipe and an ELB will not look bad...
drill a 1/2" hole for the Cat over from the sleeve...
how would you split/seperate the two after you get thru the sleeve...
you planning on using UF cable...
At 40' use a wireless remote base/charger for phone, a wireless (WI-FI) router for computer interface back to the terminal and not bother with the 5e......

No, do not run the two cables in the same sleeve or conduit. It's both a code no-no and very unwise from a noise standpoint.

All the info I've gathered tells me to "never" run structured wiring parallel to and in close proximity of, in the same raceway as, electrical (110 and 220 volt AC) runs. It's probably also true for low voltage AC. You can cross electrical lines here and there but don't do it unless you absolutely have to. Dig a separate trench and you won't have problems.
structured wiring....... what else are you are you running with the cat5

, wer ist jetzt der Idiot ?
I was planning on running two cat5e and two RG-6.I may have to punch a hole through the wall and run conduit for the cat5e and RG-6 and use the "Sleeve" for the 220v. Then run them in separate conduit and keep them about 8-10 inches apart in the trench.

are you buying it structured or just four cables ?.

You should be using metalic conduit if you want no interaction. If you use pvc you will see BIG induced voltage in the cat5. It may or may not have an effect when the cat 5 is hooked to computer but if you use the cat5 for a high impedence operation, you will see serious induced 60 Hz on the cat5. The coax will see the same situation, but depending on what you use it for and the particular equipment hooked to it may or may not degrade what you are doing.The dirt does not attenuate the electric and magnetic fields surrounding electric cables as much as one might think. I did almost the exact same thing you are doing with hot tub power and remote temperature control thru a multiconductor cable in the same trench. Had to go thru some experimenting to get the temperature controls to work. When I looked at it with a scope, the temp signal was riding on top of 30-40 volt ac signal. Now that was before cat5 even existed and cat5 is designed to minimize cross talk but I wouldn't trust it without prior testing.Nobody gets in to see the wizard...not nobody...not no how!
If you duplicated your hot tub setup now with Cat5, there would be little or no interference. You were probably using bell cord or at best Cat3 phone cable. Cat3 is good enough to prevent phone line cross-talk between pairs within a long cable. Cat5 is vastly superior to Cat3 and Cat5e is better yet.Still, I like your suggestion of using metal conduit for one or the other through the sleeve.

Yes I was using just plain old 25 pair telco cable. The cats basically improve cross talk and a couple other items as the numbers go up, but if the use it is put to is not a balanced signal around 100 ohm impedence, the cross talk specs will go out the window. I don't know the impedence of the circuitry in the temp controller I was using but I would guess it to be in the area of 10k ohm.Nobody gets in to see the wizard...not nobody...not no how!
Cat 5 is a lot better than old-fashioned multiconductor cable since the cat 5 is so intensely twisted. So long as the minimum 6" is observed and one averages closer to 8" I wouldn't worry about crosstalk. Of course a metal conduit would make it more certain, but isn't a requirement.

Yes cat5 is better, but it is not "intensly twisted" If you will open up a cat5 cable you will note that each pair is twisted differently, and that is precisely the way they achieve the cross talk figures. When you get up to cat 6E, there is a plastic spacer running with the pairs to keep them in perfect alignment with each other. All of these specs depend upon using the pairs in a balanced signal transmission mode.Nobody gets in to see the wizard...not nobody...not no how!
Compare the number of twists per inch in cat5 vs regular phone cable. It is indeed intensely twisted. The varying pitch also helps with crosstalk, but the stuff is amazingly noise-immune to outside sources as well.
If your view never changes you're following the wrong leader
Keep them as far apart as you can, and if possible separate the cat5 from the coax.

The standard here is 12" separation between telecom and electric cable, either horizontal or vertical, in any utility trench.
