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

    PIB (polyisobutadiene) tape is an excellent material but must be adequately stretched to amalgamate properly, which is tricky on small conductors. Adhesive heatshrink is also very good, both methods have insulation far exceeding that required for safety. I wouldn't fit crimps to small conductors < 4mm, as the crimps do not distort the conductors sufficiently and are not reliable over time. Z, fish glue on PVC tape is clearly useless, although I agree with your sentiment!
