Question: Is it acceptable to leave a dead wire buried in the wall, when removal is not possible or very difficult to accomplish?
If the wiring method consists of raceways, such as rigid or flexible metallic or nonmetallic conduits, abandoned, discontinued or disconnected conductors should be removed. For cable-type wiring methods, abandoned cables that are accessible and are not terminated at a piece of equipment or tagged for future use should be removed. When it comes to cables that are not accessible, common sense really comes into play. Both ends of the cable should be cut back in such a manner that they can never be accidentally used again or worse yet become energized, which obviously would create a serious fire or life safety hazard.
Always check with a local electrical inspector about the code requirements in your area.
