dead wire in wall.
My friend bought a home.There was in the wall with a blank cover. Took cover off and no wires were in it. So we took the box out so we could patch it. Then there it was a wire already striped on the ends. So I checked it with a meter. It was dead. What I want know is can we cover the wires and patch the wall permanetly.

No you can not. The wire either has to be boxed and safed off or the wire has to be removed. According to the nec you can not just bury a wire in the wall and why would you want to anyways where you have no idea where it comes from or fed from. Potential fire hazzard there.

If the other end of cable or conductor still hook up it must be accesable by juction box.

However if the conductor or cable actally been cutted off from both ends that can be abanoned cable or conductors.

If you ever run into like that good idea to take a tape and marked on the end of conductor or cable and write in abanoned cable or conductor so you know it no longer used but if still good shape some case you want to save it mark it down " spare "

dead wire in wall.
Why would they have left the wire that way?

Some homeowners do strange things with wiring, dead or not!
I don't know why they left the dead wires outside the box when they were going to leave the box. It makes a lot more sense to have the wires come into the box and be nutted safely there.

I have a few dead cables in my basement, because I have been gradually rewiring, and sometimes I just leave the old cable disconnected at both ends until I get the time to remove it completely. Obviously, in your case, the guy never removed it.

Problem with having "dead" wires just hanging in the wall is that the other end may go somewhere, and that circuit could eventually be re-energized.

It's my understanding a wire that has been cut at both ends as frenchelectrician stated is an abandoned wire & can be covered. They do not expect people to rip walls apart to get rid of old wiring. I would mark it as stated. I would try to chase it 1st to see where it goes, It could be the outlet stopped working - maybe they hit it with a nail in a remodel - so they cut it & abandoned it

But who knows? I actually came across live wires a number of times in boxes uncapped - one box was behind the baseboard - completely covered

It is a violation but a single cable can be made perfectly safe with a proper tape job.:whistling2:
