If you don't have an earth in the cable and it is buried in the wall someone could nail it and the nail would become live.

I'm lost on how the CPC helps this, in normal 3 core what is to stop the nail/screw penetrating the live or switched lived only? Or on any cable even single and earth, only the live cable could be penetrated. Isn't this what the addition of RCD protection for cables embedded <50MM in the wall was for?

Agree to a degree over this but at least you have a chance of the nail hitting the live and earth especially on a single cable.

Does this mean my tight arse way of 2x twin & earth is safer,being as there is two cpc's?

Would be safer if you had some steel conduit you could install it in:shades_smile:

I think your tight arse way is a more expensive way of doing it. But if its what you are doing you ma as well earth the extra blue conductor too, as its a redundant core at the moment. It is a fraction safer that you have the CPC and it could be hit at the same time as the live conductor with a drill, but you still require 30 mA RCD protection.

Is this rewire being notified?

Less than £50 for a wireless stat its a no brainer.

Most cost effective solution is a wired/wireless stat at about 7 foot up so the missus can't get near it:rockon:

If it's wireless she needn't know where it is, I have tried too many times to explain that turning the stat up doesn't make it get up to temperature quicker but that it will get up to 25 degrees because she's ''forgotten'' to turn it back down!

Yes of course the rewire is being notified, why did you feel the need to ask that?

Merely just asking, we get a lot of diy would be sparks on the forums these days.
