Repairing insulation

MrJack96
What is acceptable practice to repair basic insulation when it’s been nicked. Can we use self amalgamation tape or should we cut and trough crimp? 


thanks guys

    Acceptable in my view to repair the insulation, and arguably preferable to use of a through crimp. In my experience, a significant number of faults on existing installations are due to failed crimp connections.


    For larger conductors self amalgamating rubber tape is useful, not easy to apply neatly to smaller conductors, in which case I prefer heat shrink, two layers in most cases.


    It would be better practice in my view to replace the damaged wire or cable, but this is sometimes unreasonably costly or disruptive.
