How deep should cable TV wiring be buried? Where would I find the code reference?

George:
Article 820 covers coax installation but has nothing about min burial depths. I am tempted to say table 300.5 column 1 (2005 nec). This is a good question ,around here the burial depths average 2- 4" for the local cable co.

Didn't we just answer this question a little while back? The NEC doesn't cover this, I normally use UF depths while the cable guys will just make a slit with a lawn edger and stomp the cable into it. [Linked Image] Of course they couldn't care less when it fails.

Make sure you use flooded cable for direct burial or pulled through pipe underground, not regular cable.

Hal- It might have been on this forum before, if it was I missed it. And, since you have a handle on telecom stuff (per your bio) what is "flooded cable"?

George,
"Flooded" is the trade name for coax cable which is rated for direct burial. It has a grease of sorts under the jacket to prevent moisture from migrating.

Hal I always use cat 5e for this 'cause it's better'

Should I use flooded 5e? [Linked Image]

Your right it is an inside joke.

Hal has a real problem with folks using Cat 5 for every low voltage application under the sun. [Linked Image]

I tend to agree with him, it is more professional to use the right cable for the specific job.

That said I will admit I have used it in a pinch for other low voltage applications if it meant getting the job done and was still code compliant.
