Cable routing

you are wrong. If a cable is run in a safe zone for a light switch for example. Another circuit cable can be run along side that route as long as it is continues in the same plane, either horizontally or vertically, for any lenght as long as it continues along that plane for all of its route

That's what common sense would say, but can you quote any reg which says that [and hence which somehow negates 522.6.101(v)]?

Are the cables to be concealed? If so then what will be there to signify the cable is there? Bog standard cables as installed in houses need to be in safe zones: //www.diynot.com/wiki/electrics:walls.

Surface mounting in trunking may be a way forward or installing an accessory box to signify there is something there.

Do you already have RCD protection on the circuits you are working on?

How thick are the walls?

If 100 mm or less it seems you can run the cable on the reverse side of the wall.

You would think you could run any cable from any circuit in line with any accessory. After all, you can run any circuit cable in the zones in the corners or below the ceiling.

Quite so, one would definitely think that - but can you find anything in the regs that actually says that, despite what 522.6.101(v) says?

Dare I suggest that this is one of those situations in which one has to decide between common sense and the word of the regs (with consideration of the fact that, by definition, what one has done will not be visible :) ).

...provided (AFAIUI) that the doors (or other openings) are so positioned that one can see both sides of the wall from the same place!

How is one supposed to install concealed wiring for outside wall lights then, if the walls are more than 100 mm?
 
More than 50mm below the zone-free surface or use SWA, or BS 8436, or steel conduit.

[I assume you're talking about indoor concealed wiring]. I suppose that if one wants to comply with regs, it can only be done if the wiring is either connected to an accessory which creates a safe zone in the required place, or else if it's possible to put the wiring close to a corner of a room or its ceiling. ... or, of course, as BAS has just said, use some sort of 'protected'cable.

OK, thanks.
We seem to have gone from a shaver socket in the bathroom to SWA and outside lighting.
Best maybe if we end this topic and I'll seek advice
 
Not at all.

This is all relevent to your case, as the same installation methods may apply.

Naturally we are waiting for you to answer my question about is your wall thicker than 100 mm?

Thought you'd gone to bed.
 
I agree. But I'm here to tell you that doesn't seem to be happening in real life. :cry:
I've got 3 to put up on my house - for two of them the cables will be in the floor void. One will require steel conduit in the wall - I'll post a photo if it will cheer you up.
 
I need to install some points (shaver point, fan isolator) in my bathroom that has been fully tiled. Is it acceptable to run the cables down the walls in adjacent rooms and then through the wall to the boxes?
I think you have the relevant information.
It's the tiles which make it a problem.

Is a shaver point really necessary these days?

The fan isolator can be placed anywhere.
Is that the answer?
Place the fan isolator vertically above on the other side of the wall and connect the shaver point to it
