Installing cables upstairs

[Taylortwocities]

Does 522.6.204(iv) [yellow book]not allow such?

I dont have that either. But doesnt this particular query relate to cable less than 50mm deep. (522.6.101)?

To provide similar protection to armoured cable (that is allowed outside zones) surely the plate would need to be earthed?

Yes, but it isn't similar protection.
It is actual physical protection rather than ADS protection.

Also, if you look at a wall, it has two surfaces. Room 1 and room2. You have to consider the depth on both sides so installation of plates may need to be on both sides of the cable......

Yes, possibly, but what we are talking about is burying at a depth of less than 50mm.

Burying at more than 50mm. in a single 100mm. leaf would likely contravene Building Regulations anyway.

No, sorry for the confusion.

I have actual yellow book here but I am using virtual blue book.

Unfortunately, while I agree it would be logical to allow protection by earthed metal plates or capping, it's not one of the options offered in the regulation.
