Greetings,
What does the NEC say about repairing damaged wire insulation inside of a utility box? Is electrical tape acceptable so long as the colours match? Is heat shrink tubing acceptable? Should I wire nut be used even if the wire is shortened to only a couple inches instead of the minimum 6? Is the only acceptable means to re-run the length of cable between the two boxes? What is legal and what is the best most accepted way even if it is not strictly legal?
Thank you for your time, William
PS: Scenario is that a tenant decided to replace an ungrounded receptacle with a receptacle w/ ground hole (but still without true ground). Apparently the tenant had the receptacle around but no 2-3 prong converter and no car. They needed the ground plug for a power strip for the entertainment center they were setting up. The tenant did not properly pack the wires back into the box and put an outlet mounting screw through hot wire insulation resulting in a short (but no damage to the copper within the wire). Yes, yes, I am well aware that what they were doing is wrong.
