Making statements based on opinion; back them up with references or personal experience. Make sure you dry them out well. The best way to handle this is to find out where the wires are coming from and terminate them at that box. It is against most building codes to bury a junction box in the wall. However, some materials such as glass, paper, and Teflon, which have high resistivity, are very good electrical insulators. In order to completely abandon the wires underground, you need to remove them entirely from the panelbox where they are connect to prevent any accidental energizing. The first method you can use to remove plastic insulation from your cables is heating. WTWH Media LLC and its licensors. Are you talking about the free end of a wire that is still connected to the electrical system at the other end, or in a box at the other end and potentially useable in the future?

Identify those arcade games from a 1983 Brazilian music video. 110.14(B): All splices and joints and the free ends of conductors shall be covered with an insulation equivalent to that of the conductors or with an identified insulating device. While one could argue that tape represents a similar level of insulation to the original wires (hey, what would you use over a 'split bolt') I think that doing a proper taping job on the end of a single conductor is probably more time expensive than just using a wire nut. "address": { Where is this? You'll need to whack another ground bar in this box, too; for a reasonable circuit count, another Penn-Union NA-412 will do the trick, or if you need something larger, you can use its bigger brother, the NA-413. @MarkD - I mentioned he could terminate at nearest box too.
