powers runs, network runs

[jan tanjo]

Hi

If I have to run network cable and a power cable parallel to each other, how close is too close?

Is there a difference with 240V and 120V?

What about parallel distance?

Best practice is to not run them parallel in close proximity to each other, crossing each other at an angle is better. A distance of over an inch is much less likely to cause issues than tie wrapping them together.

Cat 5 cable is "Unshielded Twisted Pair" cable, so problems can arise, but it depends on the particular location and the cable run length as to how many problems you may experience.

You can buy shielded cat 5e cable....


Where are you planning on running the cable?

This one is rated for exterior use...

If it is through ductwork then you'll need to go with a plenum grade cable...

This place has 'plain vanilla' Cat5e/shield (this is what is commonly used on interior runs that don't go in troughs or ductwork)

If you do use shielded cable, make sure you use connectors made for it.

Hi PrntRhd,

When you say not run them parallel in close proximity to each other what is close? An inch, a foot? One run I kept it 6 inches away from a 240v stove line. (I can easily move it if that's to close.)

I have a nine foot run where I can keep it 4 inches away from a 120v line. I am using unshielded cat 5, if 4 inches is enough for unshielded then I'll get shielded to be double sure.

It it does anything I could even loop the network cable every once in a while.
