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

    well the QI klaxon answer is 'insulation tape' , it should not, though in practice it will probably be fine. It also rather depends if the metal is also damaged - clearly more than just a scratch, and it should be cut and rejoin, ideally with glue lined heatshrink sleeve over the top.

    If you have room then there are various types of crimps and terminals, if it is in an accesible box you could use choc block or a wago.


    If the metal is OK, and you can lift an end, and can thread some sleeving on, that may  be OK, self amalgamating tape can be OK in the right circumstances,  but not haphazardly applied in a lumpy blob, you need good access, at which point you can usually do better.
