Repairing insulation

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

  • In the past I have repaired cables buried in plaster in walls with a shallow metal box and a blank plate to cover it. This can only be achieved if the owner agrees. If the owner has damaged a cable whilst drilling the wall or hanging a picture then accessible joints are good afterwards. Sometimes I have seen cables repaired by cutting them, sleeving them, rejointing them, perhaps with small choc blocks,  and then sliding the sleeving down over the joint. If the choc blocks are staggered they are more compact in size. The joint is then plastered over. If individual sleeves are used for L and N and a larger over sleeve is slid over the whole lot afterwards that seems to me to be as good as the original cable. This is easier with dot and dab walls where the joint can be easily hidden. The repair is on a cable run anyway so is in a "zone".
