Hi,

Last wiring question I think! In the kitchen in a couple of places I've
run 2x2.5mm t+e down some 25mm oval conduit and it's a little tight
(i.e. doesn't slide about freely in the conduit).

This is only in a couple of short pieces of ~30cm to get the cable from
the sockets down below worktop height ready for me to plaster over.

Having read some old posts people have said these needs to be a bit of
extra space round the cabling for expansion so would I be better off
not using it? It was the biggest they had in the shop. I'm going tile
over the whole area so I don't want the cabling to expand and pop
tiles/grout off etc. - don't know how realistic that is!

Thanks,

Ian.

No it isn't going to cause any problem. If cable expansion was sufficient
to cause those kind of effects it would be worse without the conduit. I
never use conduit and have never had any problems.

There's no need to use conduit if the cables run vertically down from a
socket - you can simply plaster over them.

If you've chased into existing good plaster and are going to tile over
there's often no need to even make good the chase.

Cool, thanks for your help all,

Except you reduce impact resistance and have that quality hollow sound when
you or the next purchaser rap there knuckles across the tiles.

I don't do jobs at home with a view of selling. ;-) Not making good round
backing boxes etc when tiling allows you to move them slightly to get that
perfect alignment between tile runs. Which to me is more important.

The main argumenta against conduit is that it is a pain to get whole
cables through (single wires are much simpler!), and it eats into your
temperature budget a little. 30cm however is unlikely to cause any
problems with either of these - so no need to worry.
