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.


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.

Actually I would be tempted to follow the 16th ed. rules and keep them
6inches apart. You might also find that your homes plug may cause
trouble, although without trying it you won't know!


Cheers,
Rob.

Given the circumstances run a separate channel for signal cables.

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.


That *is* the case; my original question was badly phrased and information
poor, so thanks to the posters who teased out the salient facts :-)

The mains cables are already in place and capped with *metal* conduit -
I'll likely just chase another slot into the wall a few inches or so away.
I may also run CT100 *and* CAT5e at the same time, in the same conduit if
these will coexist happily enough?

Please be aware that it is reported that "Ethernet over mains" systems can
cause great problems to short-wave etc reception. If you do not intend to
listen to sw then no problem, although it might upset you next door
neighbours. As you are doing a rebuild why not just install CAT5 cabling. I
would also recommend segregation of data/tv cables from mains on safety
grounds. Just imagine if you were to put a nail through the lot.

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