Wall Mounting A TV

[securespark]

Hurrah for the cyanoacrylates!

I have used superglue to hold a short length of 6 core alarm cable in place.

That's our 50" tv, I used the following trunking in a vertical chase in the middle of the wall

Behind the unit and centre of the TV is a single metal knockout box with these trims fitted

I've got 2 cat 6 cables, TV power & aerial, 4 HDMI and 2 scart leads in the trunking and could probably fit a few more.

You can also get skirting that has a covered cutout for running cables in if you need to get them to different points around the room

Why pay all that money for decorative trunking and then bury it in the wall?

NOT ALLOWED.

Shame you didn't ask here before doing that - a classic example of unknown unknowns, I expect.

You may not have network, signal etc cables in the same containment as power ones - it isn't safe, as the insulation on the network etc cables is not rated for 230V.

Doesn't it hurt your neck with the TV all the way up there?

I assume you mean it's not rated for the heat output from being next to a 240v cable? There's about 30mm between them so I won't be losing any sleep over it

The regs prohibit Band I and Band II cables sharing the same cable enclosure unless every cable is insulated for the highest voltage present or they are installed in separate compartments of a trunking system.

I don't think he did

For what it's worth, nor would I!

Whilst I think it is technically true that the insulation of network cables is "not rated" for 230V, it can well stand that voltage - and that's before one thinks about all the insulating materials (in the 230V cable) which are normally between the 230V and anything else. If the 230V cable caught on fire, exposing it#s live conductors, if it was close enough to the network cable to 'do any harm' it would presumably burn/melt the insulation of that, too, regardless of what 'voltage rating' it had!

Kind Regards, John

Belden Cat5e is rated 300V RMS

Coax?
HDMI?
SCART?

So in 50mm trunking you have 2 cat 6 cables, TV power & aerial, 4 HDMI and 2 scart leads, and there's 30mm between the power cable and the nearest of the other 9?

Whatever their 'rated' voltage, I have no doubt that they could cope with 230V.

In any event, as I said, if heat or fire destroyed both insulation and sheating of a cable carrying 230V that was sufficiently close to some other cable to represent a risk (of conductors coming into contact) then the insulation and sheathing of that other cable would no doubt be burnt and/or melted, regardless of its 'voltage rating'.

Doe the regulations require "can cope with" or "rated for"?

The network cables are 30mm from the power lead, the rest are in between.

How many people bind all the cables in those twisty cable tidies which presents the same effect, I did look for information before doing the job and the main bit I found was if burying the live it needed to be on an RCD protected circuit which it is.

In terms of my advice to the op the only bit amiss is he should put the cable in separate trunking but even of he does that if the power cable catches fire it will melt the lot anyway regardless of how many plastic conduits there in

The regulations do not influence how well I sleep.
