Additional CPC... does it have to run in a zone?

[DNS1]

Got a load of stainless steel sockets and switches for my living room a while back, but never fitted the light switch as there's no cpc (current light switch is plastic).

Planning to drop a cpc down from the loft, but for one reason and another it's going to have to run diagonally across the wall (beam and board adhesive mean it can't drop down straight).

I know it's not ideal, but do the regs prevent the running of a protective conductor outside a zone?

Are you sure it isn't easier to do what Glenn says and draw a new t&e in using the old cable? No plastering, no soft bendy 4mm going everywhere except where you want it.

old cable won't budge mate, think the plasterer must have slapped a great spodge of adhesive over it.

I guess it was wishful thinking! Not ideal but is there a cavity?

If it was dot and dab over existing walls wouldnt your old cable still be in the original containment and easier to work out where the plasterer may of stuck it, ps in hindsight if you know you didnt have a cpc originally before the work started would of been a lot easier back then to rewire the lot properly,

Just a thought for the future

Not as difficult as you think to get it down the wall. You only need to locate the studs (dabs in your case). Then locally create a small channel the in plaster only over these points. Use the voids between plasterboard and wall for the rest. You only then need to patch plaster little bits. For customers, would use quickset plater and you'll not have to come back next day!!

ps: use proper insulating rods to prospect the wall and not coat hangers. This minimises the risk of coming into contact with live wires - how often have you seen taped up bodges behind walls?

Cheers guys.

I'll do a little investigating and replace the whole cable.
