Running 115v and cat5e in parallel but separate conduits.

I want to run cat 5e around the outside of my house and the only area it can be ran will be in parallel with a 1/2" EMT 115v Conduit that runs to a outdoor outlet and a flood light. They will run in parallel for at least 150ft. The CAT-5e will be ran in a 3/4 EMT conduit with 6 wires inside of it and will be about 2 inches away from the 1/2 EMT conduit housing the 115v. The Cat-5e will all be home runs for home automation stuff.

Any foreseeable issues with this or code violations?

Thanks

Brian

U will most likely not have an issue but if u really want to make sure use shielded/STP CAT5e...

Agreed. You've got 2 emt conduits providing shielding, along with the shielding within the CAT5e cable. It won't be an issue.

However, consider the following:
- Your emt should be grounded anyway, but double check. It'll shield much better if grounded.
- Consider going with Cat6. The biggest difference between Cat5e and Cat6 is the quality of the shielding.

I'd at least consider PVC conduit. The EMT is going to be rusting and looking shabby after a couple of winters. And then its a complete tearup and redo...not my idea of time well spent or fun.

regular riser and plenum rated CAT5e and CAT6 has NO SHIELDING. Its is called UTP- u shielded twisted pair.

If the OP wants shielded CAT5e or CAT6 they need to buy the more expensive STP- shielded twisted pair.

And the major sifference between CAT5e and CAT6 is the number of twists (5 vs 6) and sometimes, depending on brand, the conductor gauge NOT SHIELDING.

Also, some brands of CAT6 have a crosstalk divider that aids in noise reduction.

Cat 5e or 6 UTP does not have shielding. STP does. In any case it will not be an issue with EMT or PVC given the separation of the conduits.

Go to your local Graybar, Crescent, Viking, AccuTech, or Anixter with a city desk and ask for Water Blocked if your going underground in conduit. Otherwise standard riser rated from a big box store will be fine.

The difference between C5e and 6 is the number of twists in each pair and the lay of the pairs in the sheath. Then of course there are variations of each of these called big E versions and 350Mhz cables, but that's another story.

Do you need (6) dedicated lines? or could you get by with just one or two lines and a 8 port switch at the end?

ENT is a solid, continuous shield. No reason to go with shielded cable, and shielded direct burial or gel is going to be $$$$ when you find it. It wouldn't be a problem anyway.

I would recommend direct burial cable which is not gel-filled. It's been lasting a long time in flooded PVC conduit for me. Avoid CCA, both my CCA runs are now dead at this point.

I have about 2000' feet of this buried with great success, some direct:

Thanks for the replies guys.
None of it is going to be buried it will be attached to the side of the house then have a piece of "siding" which is rough Sawn cedar over it. The conduit will be weather protected and 9 feet up the wall. The 1/2 that is currently there has zero sign of degrading. It won't be 6 the entire run. 6 for the first 15ft then will be going into a j box and branching off. 5 for another 15ft branch off . The longest run 150ft will only have 3 cat 5 in the 3/4 conduit. As this is running on the outside and be branching off into rooms as it goes.

Don't do shielded unless you really intend to install it right - shield connectors, ground patch panel, etc. IMO it will be more problematic for the average joe to run the job shielded.

I suppose it's possible that I've ever only worked with shielded Cat5e cable. I've cut, stripped, and terminated a bunch of Cat5e in my day and have always encountered a foil wrapper under the jacket.

Twists are a way of providing noise cancellation. Very similar purpose/effect as shielding but yeah, you're right. I was trying the keep the reply short and simple.
