Running Phone Lines - Perpendicular to joists?

Hi, I'm moving some phone lines in my basement and I've got a run of five lines perpendicular to the joists. Does code say anything about how to route these lines? Do I need to mount some 1x3s to the bottom of the joists as you do for romex? Or can I just staple to the bottom of the joists and have them span the gap?

Thanks.

Code does not say much at all about low voltage wires.

Run them however you want. For your own piece of mind you may want to protect them, but that's your call.

I recommend that you don't run them parallel to electrical lines.

Good Morning...

For my taste, I would prefer to run the wires up in the joists.. But that is me... Now if this is a crawl space that you never have to worry about, then by all means just staple them to the bottoms if you would like...

Now as for code, unless it is area specific, there is no code relative to low voltage lines like you are speaking about...

Good Luck and Good Wiring...

If it were me I would run conduit shouldnt cost but a few bucks and that way when someone decides to hang something on it (and they will ) you dont have to worry about the cable

the problem is if someone hangs something on it the cable wont break but over time the staples could wear the jacket down and cause a short or static.

First of all, there are codes for running low-voltage wires (as RaCraft mentioned) you cannot run any low-voltage wires parallel to line voltage wires. Keep at least 12" between them (distance may vary by locality.)
You can only cross line voltage wires at a 90* angle.

Secondly, conduit is overkill for any residential phone lines. It's not required and it's certainly not necessary.

The best thing to do is keep the low-vo wires as close together as possible and try to run them along the edges of the walls. This keeps them from just hanging from the ceiling/joists and protects them from "flying objects" (like broom sticks, baseball bats, etc.)

Also, be sure to use T-25 staples (or wire staples of some sort) to keep from knicking the wires or peircing the jacket. Instead of wire staples, though, I recommend using the D-hooks - this keeps from damaging the wires, and also allows you to easily move the wires later, if need be.

If you really want to do it right, though, get a 3/4" auger bit and start drilling - that's the only sure way to do it right.

Good luck!

those are standards not codes big diffrence and the standard where written tword tdata lines and lines used for electronic key systems rather than POTS lines



as to running conduit

I never said it was necessary, just a good idea and what I would do

the best practice is to protect the wire for a few dollars and not much work I would run conduit I have seen wire damaged in open areas by peaple hanging things form it a wire bridging two joists is a great place to hand clothes on hangers to dru amoung other things
