Cat 6 Wiring and Electrical Wiring

[Industrial Toys]

Spent a little time searching. Irritating. Just homeowner opinions and nothing as for industry guidlines. SURE it will work, at what degraded speed? I could be totally wrong. I put miles of EMT conduit in my house in the 90s. I LOVE conduit. Never thought I could use it for CAT5 and 6 from what I recall reading. It would sure be NICE if I could. I will investigate further.

I know we ran a 2" conduit to the back of a large Pharma warehouse and the performance of CAT 5 was so poor they went with fiber. I attributed it to the conduit as it was not the 1000 feet you should be able to go with cat 5.

You are.

Totally wrong.

Sorry, but there it is.

Putting either CAT 5 or CAT 6 in a metal conduit will certainly not "add capacitance". It's been run that way for decades. Literally, decades.

You can't run CAT 5 for a thousand feet. That was very likely your issue. 330 or 333 feet is max, and your connections have to be PERFECT for that to work. Most strive for under 250 foot runs.

Appreciate your input. Those are not the figures I recall hearing as general guidlines. Of cource you will add capacitance to ground, running any cable in a metal conduit.

It doesn't seem right to me. I have heard of a single metal strap really effecting the performance of the run, but you can run the stuff in hundreds of feet (let's say) of metal conduit without effect? THAT, just doesn't sound right to me. Like I said. I could be dead wrong.

I would very much like to see what IEEE has to say on the matter. I would, as I said love to be wrong on this.

Well I kind of do this stuff for a living, and have for many years, but you are certainly welcome to read until your heart's content. I take no offense to your doubts.

100 meters is maximum length in or out of conduit. It makes no difference. I was only an engineer for a telecom for 16 years, and a technician for another for 21 years before that.

So did anyone ever check the bandwidth and error rate of CAT 5, in and out of conduit?

you do realize that wiring cabling trays are steel or aluminum. they run for 100's of feet in many, many buildings. including telephone companies and internet provider facilities. the cat6 wires are laid in them.

and in metal stud buildings there even run thru walls horizontally in conduit.

A cable tray is ribbed or vented, whatever you want to call it and not surrounding the cable. Just saying. But one metal strap will destroy the performance?

Looked at the picture. Interesting that the trays are wire racking. Is this for cost? Many old trays were solid metal. IF there was any truth in CAT 5, not being supposed to be installed in metal, this would make some sense.

And on top of that have you considered that Cat5e and Cat 6 cables are often bundled together in large bundles. How about all of that copper wire surrounding any single cable?

I don't know where this Cat cable in conduit question came from? It is a new one on me.
