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 have been an electrician for many years. I normally squeeze the P.V.C. T&E sheath with pliers so that it breaks at the end, then I recover the C.P.C. and use it as a cheese cutter wire to strip the cable back to the required length. I have never had a C.P.C. break or stretch. Some people use a knife and cut, or partially cut, down the middle of the sheath first. Only 1.0mm2 & 1.5mm2 T&E cables uses a 1.0mm2 sized C.P.C. others use a 1.5mm2 C.P.C. so it is stronger. The 1.0mm2 T&E or 3 core and C.P.C. has very thin weak sheathing so is easy to strip back. On site it is all about speed and efficiency. We do not need to clutter up our tool boxes with expensive unnecessary tools.
