"Was that that new thing called 'sarcasm'?" ~ Jack Black in Shallow HalI thought youre supposed to leave the ends blunt cut with just a little copper past the insulation on the hot conductor with the end gently resting against the painted surface, so that after many years of normal building vibration the wire end makes its way through the paint and faults (not that I have ever encountered this.......)
I'm with you on this. probably can leave cut end as is and not really have any code violation, but recommend covering any exposed conductor with something non conductive at very least.I don't think it matters. Tape, cap with wire nuts, lever locks, stab ins or similar.
