Does anyone know anywhere in the regulations that it states I have to use capping to protect cables when embedded in plaster as I am currently on a rewire, it says in on site guide that if there's no rcd protection it does require metal earthed capping
The standard sds bits we use will fly threw capping? That's how we fix it on new builds with concrete block work plug and screw using an sds but rewires tend to use oval as less of a chase
As Im clearly faster than everyone on here at rewiring I shall reveal my methods of capping
I use plastic where possible, for a double socket I drill 1 fixing hole just below the socket. I jam the bottom of the capping down the chase behind the skirting and fix the top of the plastic capping with one screw straight through the side of the capping into the predrilled raw plug. Quick easy and neat.
When I have a few cables in a raggle I use metal capping with an earth flyer. Reason being, its more rigid and holds the cable in place. I screw straight through the edge of the capping with a battery gun and into the predrilled hole ( get the right screws and the right posi bit and you can screw straight through capping without pre drilling) A full length metal capped raggle can be held in place with 2/3 screws if done correctly. If its the main raggle with all circuits to board , Ill fix all-round band at a few points and use that to hold the capping.
see....thats how I rewire in 2 days clipping every cable with T&E clips? screwing with hand drivers ? ......stop now.
Large piece of unearthed capping in the wall....lady puts picture up.....nail through capping and through live core only...full length of capping is live and no trip.......thats bad.

I was taught to always earth capping..old company still does it. Safe zones yeah but what if you install and a sharp edge of caping has sliced into a cable by accident ? you have just installed a large piece of metal in the wall that is now live...I earth it then I know I don't have that problem as any contact to live will also be to earth and trip.
I think it was councils who insisted on this even when not required..but Ive always just thought it was good practise too ! Id rather do that than potentially make a wall live, not know till someone soaks it with paint and gets plated.
