low voltage wiring code?


Is there any code for installation of low voltage wiriging such as thermostat wireing, doorbell, Cat5, telephone, coax? should it be tacked down every 4.5 ft like electrical wiring? anything specific that needs to be done to be up to the standards currently for installation? I have a ton of cat5 and coax just laying loose right now in a drop cieling in the basement... I want to get it done right... thanks!

At least one thing I know is that low voltage must be seperate from high voltage.

As an example, if you drill a set of holes through studs to run wire for a set of electrical outlets, you can NOT run your low voltage wire through the same set of holes.

well looks like I'll be fishing out all the wires the house builder installed then *LOL* in some places they ran the phone and coax through the same holes 5 high voltage wires run through.... always wanted to get rid of that thought since it can produce hum on the lines if they run parallel together.....

Yes, you want at least 6" seperation from any low voltage cabling and high voltage wiring. The best way to run the cable is to use "J" hooks, they work the best. Never use zip ties, you can damage the cable.
