Ideally wires going into a wire nut will have only so much bare wire so that that bare wire is entirely underneath the nut and you only see insulated wire coming out the bottom. It seems like by design there's maybe a 1/4" of insulation tucked up in the nut (measuring from the nut's bottom edge).
My question is what if one of the wires in the nut has its insulation cut point at about level with the nut's bottom. So that if you look straight on from the side you don't see any bare wire, but if you tilt the nut so you can underneath it you can see the bare wire just above the rim.
I can't imagine this really matters, but thought i'd check first. I'm finding this happening to me occasionally as I do a project. It's when I've got 4 #12's to fit in a red wire nut. I twist them with my klein's first (as directed by the inspector). Occasionally, although the wires start with the same amount of bare wire all lined up, one of those wires slips down a bit during the twist, so that if I were to cut off the bare twist so that that one wire will stick up well in the nut, the rest of the wires would be pretty short.
Thanks for any advice.
