I was using pliers to pull my cable a little bit further in to the blue junction box so that I would have some Romex insulation sticking into the box, but in the process managed to make a small nick in the hot wire and can now see the copper.
The cable is already pretty tight so I can’t just pull more in and cut off the damaged part. I do have about 2” of wire to play with if I were to cut it off. What options do I have? Can I just wrap it in electrical tape or use a push in style connector with jumper?
