Home network installation

[bdt]

I've always been a bit scared about running network cables like electricity cables though: next to other mains power cables and with right bends (especially forcing against the wall with a corner). Haven't you had any issues doing that?

IANAE but to my knowledge (from speaking to at least one) it's not right/in breach of code to run HV (so mains) and LV wires (so cat5, etc) in the same conduit.

I'm looking for a home installation service in Jhb. I've seen a few websites, but figured I'd check in here before taking a chance with any of them.

I've actually got all the cabling, access points, other network hardware - I basically just need someone to pull the cables through the ceiling.

Any suggestions welcome.

The topside of ceilings are hugely variable: I've been in one where I could walk upright for the most part, and another where I had to do a leopard crawl to get to the bloody cable coming in from the roof to it's hole so very close to it, but only reachable by lots of misery. How bad is your roof?

You can legally run cables with different voltages in the same conduit , on the condition that all the cables insulation voltages are rated for the highest voltage in the conduit .

I have never seen network cable rated for 230V

Subtle semantics; in effect I said that very thing: network cables aren't mains-voltage rated. But, from what you said I read that I can run Norsk, etcetera in a conduit ...and then some ripcord - that stuff that is used for desklamps everywhere and have, say, 12Vac on it; and be fine because the *cable* is mains-rated.

Yeah but it's the interference that bothers me

Bit of both.

Getting to the perimeter is always tough, but only 3 of the points are at the perimeter. The bulk of the cables will be coming up trough an inner wall (garage) where it will be distributed around.
The main issue is that there's a lot of cross beams so ever step requires a certain graceful contortion that I sadly do not possess.

Electrician it is then.

Get an electrician to run the wiring for you, and terminate it yourself - assuming you are capable of terminating the ends yourself - its fairly easy, you just need a crimper and a punch tool. You could be lazy and just crimp both ends with an RJ45 instead of going to a jack plug one end.. I usually try to do things properly and run to a board/ patch panels.
I used to do it for a living though not so many moons ago.

Any electrician will have plenty of experience pulling wire, and running piping.
Make sure that they put it into conduit.

I've already crimped one end of the cables and worked out all the lengths. The keystone jacks are all awaiting their final resting place in the wall boxes.

Yep, I'll definitely be going the conduit route. There's already a spider web of coax cables in the ceiling from the DSTV noobs.

Note, when I say conduit - USE A SEPARATE NEW CONDUIT for the ethernet cabling.


Also think about what other cabling you need in a room while you have an electrician.
i.e extra plug points, HDMI (over Ethernet for long cabling) or speaker wire etc.
It pays to do everything at one time...

Yep. There's about 8 Ethernet points, 2 AP's, 4 IP cameras and 3 telephone points.
