I need to run both HDMI and Power down some trunking, i think this may cause interfearance. is this the case? and if so is there trunking that makes this possible without distortion?

Re: Sheilded trunking?

So I began and channeled into the wall before decorating this room,










so i can run HDMI, CAT5, USB and some spare CAT-5 as a Pull-through









but imagine the bottom box being a 3-pin power, which is why i added the other box, so that whatever TV i choose there i can replace it.

I will be running the power in it's own channel, but there is no sheilding.. is that ok? will i get interference?

Thanks

Re: Sheilded trunking?

Hi, you should get away with that in terms of interference issues. I've got my tv's power running in 2 channel PVC trunking with no issues..

You will probably struggle to pull cables down that, especially if you're putting the socket on a ring main (2 x 2.5 twin and earth). Also it looks like you've used a light switch back box for the power socket which you will probably struggle to get a socket in there once terminated properly.

Personally (as an electrician) I'd have done two chases and had the sockets next to each other rather than one on top and run the cables before any patching up using 20mm PVC conduits (connected to a deeper box with PVC adaptors - mostly in case you need to pull anything down in future) for the AV stuff and PVC capping for the power. Also, you shouldn't run power cables through that data box really!

It's also too close to the surface to plaster in properly judging by the picture.

It will work, but doesn't meet regs and could be improved.

Re: Sheilded trunking?

You should always try to maintain a 50mm separation gap between any power and any other cables. In practice what you've done should work out fine.

Also, as the previous poster mentioned, your trunking doesn't look deep enough; where possible try to leave at least 8mm from the top of the trunking to the finished plaster level.
