And of course, macmikeman, steps in with a completely different outlook. While I seldom tape wirenuts, I wish that there were a code requirement for taping a certain type of wirenut. The hard plastic ones, sold for many many years by a certain very large industry leader wirenut company I am not going to name. I have come across thousands that have cracked in half and either fell off, or are about to. In commercial buildings it can be hazardous just removing a cover from a j-box when that type was used and not taped up. And not always due to lousy connecting on the part of the original installer. Many times the wires were twisted up together all nice and tight, with the internal wirenut spring still around the ends of the conductors, but the two halves of the plastic part laying on the bottom of the j-box. Now I am not charging that allways this is the case, but often enough. I bet I am not the only one here who has seen this before.
