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've just pulled some 1.5mm2 to 110% of length before it broke, and yes the force is far more than for cheese wire stripping. I still was surprised how far it went before failure. There is a reason they don't make springs out of copper. and why it is a so-and-so to machine.
