Terminating Twin and Earth

nicemark
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.

    Of course when using the cpc as a cheese wire it isn't just being stretched, it's being bent under load then pulled straight at each point along its length. What effect that has on work hardening, waisting, nicking etc etc I do not know.
