Cabling advice needed please :)


[link to this post]
 
Hi,

I am looking for some advice for a Cat 6 cable installation I am hoping to install in my house.

My openreach master socket is located in the entrance hall of my house. Behind the master socket is an old disconnected phone extension that runs through a conduit to the attic of my house.
I was hoping to use the old extension cable to pull a Cat 6 cable to the roof space and then I can feed that down a tv aerial conduit to my living room tv.

The main issue I am seeing is installation of an rj45 faceplate beside my master socket. The old phone extension feeds directly to the master socket back box, I donít want to damage the master socket to allow the new cable to get to the new face plate.

I was wondering is there some way of converting the back box for my master socket to a double gang, keeping the master socket intact on one side, and a new rj45 faceplate on the other side. Is that possible? I donít want to spend the money buying materials if I wonít be able to install it. Any other advice you can give would be appreciated.

Thanks

Rather than getting a double box you might be better off placing another single next to it (close up) and drilling through. I've had a double single (two boxes welded together) fitted, replacing the original single back box and I am not happy with it as the shape of the master socket isn't great for butting up due to the profile of the casing.

If conduit (plastic pipe) has been fitted then you should be able to pull the cable through. However, if it's been hidden behind dot and dab you might find some friendly electrician (thanks dad) has decided to use cable clips which means you have no chance of pulling through a replacement cable.

Thanks for the advice Gary, I think I will go with the single faceplate and drill through option. Conduit has been fitted through the wall cavity so i am lucky there smile

Depending what connections you are actually making through the Cat 6, could terminate the Cat 6 in an RJ11 to plug directly into a filtered faceplate on the master?

I fed an ethernet cable next to the TV coax in my house, I suspected that there was a gap in the conduit between the two floors that made doing this more difficult than I would have liked.

DISASTER, I went home to investigate and the extension is indeed clipped frown

If you have dot and dab you can knock (gently!) on the wall and you will hear the sound change. Deeper note is where the dabs of adhesive are, higher pitch is where there's a gap. This should give you an idea if there is a path. You can then use something like the below to pull cable down (pull down, don't push up).

If it's close to the corner then you might be out of luck, but if it's mid way through the wall you might get lucky.

Another alternative if you have drylined plasterboard walls fixed with nails is a magnetic stud finder

I have used one of these very succesfully

A cheaper alternative is to take apart an old hard drive and remove the voice coil magnets used for head positioning. Be careful they will bite. For added tricks dunk them in some IPA for a week and the glue will soften to let you remove them from their backers.

As someone who has worked building stud partitions and dabbing plasterboards to solid walls, I can say that you will have a difficult job if not impossible running a cable behind the plasterboard!
If the wall is a metal stud partition it is easy to run the cable as metal stud partitions normally do not have horizontal fire breaks but will have insulation blanket. If the wall is a timber stud partition it is going to be almost but not necessarily impossible to run the cable as it will by law have horizontal braces as fire breaks plus insulation blanket! I say not impossible as there are tools to drill through the horizontal timber braces, but the price of the tools will probably give you a heart attack!
If the plasterboards have been dubbed on to a solid wall you will be extremely lucky if the adhesive dubs are all in a vertical line!
You have quite a job in your hands, and I wish you good luck with trying to feed a cable behind the plasterboard!

Iím assuming you are not from the UK with your descriptions. The horizontal braces are commonly called noggins, and are used in the UK for support to stop twisting rather than fire proofing. I am not sure what you mean by fire insulation as this is something existing houses in England do not usually have / common at all, they are usually hollow cavityís. Businesses tend to have better quality fire boarding plasterboard with intumescent sealant on joints and if lucky putty or similar in the dry lining boxes. Businesses also tend to be metal framed.

To get through the noggin worst case you would simply make a small hole below it and drill through it, worst case youíd need a small access hole above too. This is then patched up and painted. With a lot of UK sockets in newish 2000 ish houses being quite high up you can sometimes use long drill bits, or adapter with drill bits on.

With regard to Dot and dab, routing cables is a regular job for most electricians. Itís not impossible at all just because the dabs are out of line. The rods or fish wire devices you can get will twist around them (although it takes time and patience) itís got to be one of the main advantages of that kind of wall. Iím not an electrician but Iíve found it relatively simple to run cables via this type of wall. Worst case if you canít get round the dab is cut a hole and chisel a route through and fill.

The easiest solution here is to just use the existing wire using some ethernet extenders or moca or powerline technology. Running the wires sounds like it will be a really tough job. frown
