View Full Version : Low voltage wire question

Are there any issues with running low voltage (speaker cable, HDMI, component, etc.) wires together in parallel (close together) or through the same holes?

Thanks!

I don't think so. Even so, you'll probably get some recommendations to spread them a bit if you can. I ran them together in my HT and haven't had any issues.

no , no problem. keep away from 110v

Low voltage is fine bundled together as long as it is kept away from power runs.

Thanks for the responses. My low voltage lines are well away from the high voltage lines.

I'm so glad I can run the low voltage lines together - I have a lot of low voltage lines!

old post, but what exactly does "kept away" mean :) .

this is what i have. between the same floor joist i need to run some Romex for the Powerbridge i am running for the PJ. i stapled it near the bottom of the joist.

above this will be my 2" run of conduit that holds my two HDMI and one component. these cables are the heavy duty 22 awg in wall rated ones from monoprice.

is this ok. they will run parallel. i cant really find a better route from the PJ location and equipment closet. thanks. later.

What does "above this" mean :) How close? an inch? You can only do what you can do and hope for the best. Signal cable laying directly on top of and parallel to a power run for long distances is the worst case scenario. For every doubling of the distance between cables the amount of energy that can be induced in them goes down by a factor of 4 (inverse square law). Try to put as much distance between the power and signal as possible. That is not to say that you will have major problems with a conduit at the top of the joist cavity and the romex stapled at the bottom, might be just fine. I suspect that that particular scenario would not pose problems under most circumstances.

usualsuspects, what a great move :) .

the joist cavity is 9". with the romex at the very bottom and the conduit as high as i can get i would say the distance between will be about 4". the romex is for the power bridge, which is just an over glorified in wall extension cord. but power is power i guess.

i have stared at the space for hours and cant seem to find a better route. it is what it is at this point.

thank you for the help.

If you could move the power to the other side of the joist cavity (not in the next cavity over) that should be plenty of space. You can always dill a hold through the joist at the last foot or so of run and bright the romex across. Hope that makes sense.
