Cat 6 Wiring and Electrical Wiring

[drssg]

If I may piggyback on this topic a bit, are there any special considerations for devices that get their power over ethernet?

I have a network camera in my barn that uses POE, and the CAT5 line going to it along the inside wall of my barn is not in conduit. I never even thought about it until reading this thread, but does that add hazard for fire or shock? All the high voltage lines are in flexible conduit.

Some of this discussion my apply to Cat 3 or lower when used for data. We ran it all the time in conduit, Several 100 pair cables in 4" riser conduits between floors. But that was all for voice on analog key systems. Once the big push for data started, the push for Cat 5 started. The higher twist rate was supposed to kill most of the interference problems and increase transmission rates. Back then, they strived for specific installation practices, including minimum bend radius and maximum strip length in connectors and patch panels. They were supposed to test everything to 100M data rates and even a single problem somewhere along the path could cause the test to fail. It may well be that there are some documents out there that say not to use metal conduit to avoid signal loss, but that was never a real in-field practice. Too many local codes required metal conduits for fire reasons.

Current for POE is so low is shouldn't ever matter. Make sure the path is clear so the cable isn't likely to get damaged by tools or whatever and there should never be an issue.

I would NOT run the CAT cable in the same conduit as the high voltage cable. I would run the CAT or fiber optic cable on top of the high voltage plastic conduit, underground.

Only other option is to maybe run a WiFi antenna and send the signal to the other house?

Any other options on how to run internet to the main house from the guest house?

POE is 48 VDC, nothing to worry about

Thank you.

This looks like something that would work.

The "shield", on shielded cable, is a metal wire, or metal foil wrap around the conductors.

How could that be good, but a metal conduit around it instead of a shield, (being one wire in one conduit), which principally have the same effect, be bad?

Well, I looked and I looked and I looked. Nothing about conduit. Just a few stupid remarks about cable being damaged by burrs. DUH! Funny though, I saw hundreds of pictures of CAT 5/6 in trays, in ceilings, in racks and NOT ONE coming or going in conduit. Just saying.

I will have to assume you guys are right and I will use my conduit for CAT 5E without reservation.

I had to think of a job I did twenty years ago. Owner of a company/factory decided that ALL wiring had o be in conduit. Paging, alarm, CCTV, telephone, Network. I didn't run the network cable, but someone certainly did. It was a money maker, but boy what an eye opener. A simple hundred foot run of security cable through an office ceiling now became an excercise of pulling through six boxes,junction boxes, 90s and so forth. And much cabling, unlike electrical, doesn't permit splices. Yeah, running hundreds of feet of RG59 in a network of conduit and boxes is fun.

Many commercial applications run CAT in conduit due to changes and upgrades being often. Makes it easier to replace runs. Smart installers use a minimum size 1" conduit to make it easier as the small wires in CAT cable will stretch and break on hard pulls. Use lots of pulling compound also. Common to run higher pair content for the same reasons, to use an extra pair if one fails. Even twisted pairs can pick up interference if run next to things like fluorescent lights that emit Radio Frequency waves; good case to use shielded cable; been there done that. Expensive submergible cable is available for wet locations and direct burial.
