CT100 shielding

As my installing-a-new-satellite-dish-for-freesat project grinds
forward, I've come to the point where a plasterer is about to make it
difficult for me to change my mind.

As it stands, I plan on running my cable in the same channels as mains
power. Am I likely to have problems if I do this *without* additional
shielding on good quality CT100 (I'm using Bill W's site as a
reference) ?

If it makes any difference, I also use Solwise Homeplugs for some of
my home networking - don't know if that's likely to increase the risk
of interference.

For those who might not have come across these, they're "ethernet over mains
power" adapters. Since they provide at least 14Mbps (mega-bits-per-second)
throughput, they presumably use higher frequency carriers. It is claimed
that they only work within a single ring main/spur but colleagues report
that they seem to work fine all around the average home.

There are also faster versions that claim up to 200Mbps and thus presumably
use even higher frequency carriers.

Thanks, should have made that clear. These are the relatively tardy
14Mbps version. I'd echo your colleagues' assessment - they work just
fine, with little loss of bandwidth in less than ideal situations.

It is never good practice to run any cables in the same ducting as mains.
Given the circumstances run a separate channel for signal cables.

The mains cables are capped at every point, so I don't think it's a
particular danger. I suppose I'm really asking "can I run CT100 within
a few inches of the mains"?

Low voltage and mains in the same channels!

Tsk against IEE reg's (hence building reg's) IIRC.

In the same piece of conduit or trunking is wrong. But in the same channel
cut in the wall, I don't think so.

and you can have ELV in the same trunking as mains if the wiring is insulated to the higher voltage standard.

I've never had a problem with CT100 doing this. Had plenty with cheap cable
though.

When he says 'channel' after mentioning plaster I assume that he means that
he will take a chase down the wall wide enough for the two cables. If so,
whether he uses two narrow pieces of plastic capping or one wide one is
another matter, although I expect there's some reg or other about it.

My answer was based purely on EMC considerations.

Yes, no problem.
