I have a couple simple (?) questions about using wire nuts. I am swapping out my old lighting switches for some newer Insteon (home automation) switches. These switches have stranded wires come out of them.
1. What is the proper way to wire two copper wires with one or more stranded wires? Out of the electrical box, the copper wires have all been pre-twisted with pliers - very professional looking. Do I simply put the two twisted coppers (still twisted) in the wire nut next to the stranded and twist the wire nut? Cut off the twisted copper ends and try and re-pre-twist with the stranded included? (Pliers don't grab right.) What's the secret?
2. As a matter of curiousity, when wiring a new outlet, how much of the romex sheathing do you generally cut off - i.e., what length of individual sheathed wire do you leave?
