External lights - Help needed!

[rossage]

Hello all. Any one installed 'brick lights' before?

I am having a brick wall built tommorow and the missus has decided at the last minute that she wants brick lights incorporated into the wall. I have a few spare ways on RCD side at fuseboard so it will be on its own circuit. I need to run the cables as he lays the wall, which is only going to be one course deep. My questions are as follows:

1). 1.5mm T&E is more than capable of the load, but i'm not sure if it's suitable for this type of outside installtion? Is there a special weather resistent equivilent I should use? (bearing in mind there is no room for SWA or conduit)

2). The cables will be mechanically protected by the bricks but where exactly do I run the cables and how do I run the cable without damaging or crushing them?

Any help greatly appreciated.

Thanks

What sort of wall is it? Double skin? Single skin with soil behind?

If its a double skin, run the cable in the cavity (though this is frowned on, you have little option) If its retaining soil behind it, run the cable in conduit fixed to the wall before the soil is backfilled.

New circuit, notifiable

Nobody uses cavity walls outside, what would be the point?

It may be a 4" wall or a 9" one, but either way there will be no cavity.

Of course. Oops.

TTC - I'm aware this is notifiable work.

Thanks to all for replies

as you said "which is only going to be one course deep" I am presuming you mean a single skin wall, i.e no cavity, you will have to wire the lights in conduit or swa when the wall is finished on the back of the wall.

You could give the builder the lights to install as he builds the wall but you cant wire them in untill its built.

It's not.

Why?

No room where?
