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.

    I found that you need to take it steady to get the most elongation. I think that if you go quickly, a smaller segment begins to thin and once that happens, it is the weakest point and fails sooner. It would be interesting to do some properly calibrated experiments.
