Terminating Twin and Earth

I have been arguing about the methods of separating out the ends of twin and earth cable.

An old accepted trade method was to simply grip the earth wire and tear it out of the insulation to split the ends open.

However this puts considerable strain on the earth wire and in the case of 1mm wire it is very easy to stretch a significant amount.

I was wondering if you there is data or evidence to demonstrate that this method is not acceptable.

so now I am puzzled as to why stressing the CPC has not been made an issue before, particularly on the small CPC sizes.

The C.P.C. is strong enough to cheese cut through the outer P.V.C. sheathing of smaller twin and earth cables at room temperature, or slightly below, because the sheathing is thinner and more easily cut than with larger cables. Anyway, the 1.5mm2 C.P.C. and above of larger cables make good cheese cutters once the end of the cable has been cut slightly and the cut started. No problem.
