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

    Both of the materials I have suggested are much more fireproof than PVC Andy, please be sensible. Crimp connections made properly are not subject to overheating. This idea you have is simply daft!


    Why the comparison with PVC? Most electrical enclosures aren't PVC and I suspect those that are are sufficiently modified to be able to pass a glow-wire test at least. In poured resin joints I'd imagine that the hardened resin forms a suitable enclosure rather than the mould. I think it's confusing to suggest that meeting the requirements for non-accessibility is the same as meeting the requirements for enclosure - 526.5 and 526.2 are quite distinct requirements.
