Buzz-light-bulb

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 simple solution if you are determined to use capping to aide in the installation of cables/protect them from the plasterers trowel is to use plastic capping! Metal capping is a silly idea IMHO.

Thought you were in favour of the silly metal capping and earthing regime.

Plastic is ok until the cold weather sets in and it cracks when trying to cut it and fix it.

I think you will find on new builds it is. Obviously not possible on rewires, which seems to be the brunt of your business

personally I think twin and earth clipped in a bare raggle looks pretty rough....yes it complies with regs but I just think it looks a bit DIY. Capping is much neater job.

Once it's plastered over, can't see what difference it makes how it's installed as long as it complies with BS7671

on domestics i use pvc oval tube for 2 reasons.

1. clips are plugged and screwed. no chance of bashing your left mitt with the hammer.

2. if some numpty does drill/nail a cable, it's easy to rewire the drop. also, on switch drops, as long as the tube is big enough, it.s easty to draw in another cable when customer decides they want another set of lights fitting.

You could realistically say the same for SWA cable that's been imbedded in a wall or whatever. The SWA isn't going to stop a nail either, but it doesn't require RCD protection!!

Apart form the fact that if you smash a nail into a live conductor on a swa, your breakers going to trip, where as if you smash a nail into the live side of some T&E covered by metal capping, **** all is going to happen. (RCD's aside)
