Optimal NW wiring

[Bob.]

I’m close to finishing an office reno in which I’ve installed several grey electrical conduits and boxes to accommodate mostly cat5e cabling. However, in a few conduits, I will also require coax for cable (TV and modem) and telephone (for which I guess I could run cat).

Questions:
1. Will the coax or telephone interfere with NW data transfer if run in the same conduit (conduits are 1 1/4" ID)?
2. I have a 250’ roll of CAT5e twisted pair I’d like to use. I bought it at Lowe's, and it’s outdoor, solid strand. I’m not sure if CAT5e comes in stranded, and if so, is stranded the better way?
3. A few of the conduits have electrical romex running past (perpendicular). I am arranging the romex so that it ‘loops’ around, giving about an inch clearance. How much, if any, interference could this cause?
4. Any additional suggestions or warnings welcome.
Thanks,
Bob.

1. Shouldn't. The coax should be shielded.
2. Horizontal cabling should be solid. You want stranded for patch cords (better flexibility, but higher attenuation).
3. Perpendicular is what you want, it *should* be fine. Hmm..romex? Is this a home office? It's generally not allowed in commercial environments.

Good luck.

Hi NP. Thanks for your response.

These runs will be both horizontal and vertical.

Yes, it's an office in my home, permitted and in code. Again, thank you for your remarks.

In a home there is (barely) no such thing as "vertical wiring." Everything you have would be considered a horizontal run.

Vertical runs typically are run in buildings that have dedicated intrafloor spaces (typically called a riser.) So: All of your in wall Cat5 should be solid and terminated to keystones / patch panels where applicable. Coax is a low voltage system and typically doesn't interfere with Cat5[e]. As for the high voltage whips, typically they only present an issue if they are running parallel to the data for several feet. Crossing perpendicular is rarely an issue at the residential / small business level. If you were running them in an industrial environment [ie 480V motor drives etc] I would be more concerned.

And sorry...horizontal wiring in this case...doesn't mean horizontal 😉

Quick search finds this definition: "The cabling from the workstation data outlet to the termination point in the IDF or MDF (patch panel or 110 block)." So basically from the outlet to the patch panel...even if it travels "vertically" in the wall, it's still horizontal. As imagoon mentioned Riser runs are more what you find in commercial/industrial settings, most often the backbone between telecommunications rooms.

Apologies...I somehow lost track of this thread. Thank you both for the informative responses. Good information goes a long way! Thanks!
