CPR Compliant cable issues?

2011

A requriement of IS10101, the National Rules for Electrical Installations, is that cables shall at a minimum meet the requriements of Class Dca-s2, d2, a2.

Personally I think this is a good idea. Lessons should be learned from tragities such as the Grendfell Tower fire.

However, I have heard that some REC's have had real problems trying to strip domestic electrcal cables that meet this requriement. Can anyone shed any light on this or are there just a few isolated instances?

It is much harder to strip. I’ve found that by pulling the outer core of the 1.5 and 2.5 instead of the inner earth as I’d normally do works better. A Stanley knife to cut the end off. A sharp pliers is definitely required for the inner insulation whilst stripping to the conductor

On bigger t&e then a Stanley down the centre is required

I’d say a bit more practice would get the speed up.
The bigger issue is that is not as flexible whilst pulling in through joists and is a pain to push 2 cables down a wavin

Bigger holes and less cables per hole

All new work priced since end February must be to new regulations

There is a class of cable stripper of which this is typical :

We used them to remove jacket on stuff like 50pr LSZH jacket comms cables. Would they be worth a try ?
Could also look into what they use in U.S.A. where LSZH jacket has been the norm for decades.
