Installing an outside outlet about one foot away from present(inside) receptacle(outlet). In the process of pulling the black, white and ground wire into the outletI I pulled the sheath off. I went ahead and installed receptacle(outlet) which works fine. Is there any concern about leaving the wires unsheathed in the wall? Please advise.

Yes pull a new piece in. The sheathing is there for a reason. One being to keep the wires next to each other so their magnetic fields will cancel each other out, reducing inductive heating of the wire insulation. Suggest stripping the sheathing of a new piece on both ends and taping the sheath to the wires a little before pulling it in. Should help keep it on.

Thanks for the advice. I will have to remove the wires from the outlets(ugh) and begin with a new piece of 12/3. I cannot get to this right away but will do it tomorrow. I do not plan to use these outlets for the present time i.e. nothing plugged in.

Even with nothing 'plugged in' you should kill the circuit until you fix it. Just in case you don't get to it tomorrow ;)

It will be safer and it will remind you to fix it.

I can only guess you have a black,a white,and a bare copper which is a 12/2 nm. I agree with the other responders that say redo it because it isn't an approved wiring raceway/metheod.

One last question! I still have the unblemished sheathing that was pull off the three wires. It can easily be slid back on the wires connecting both outlets. Would that be adequate?? And yes I have killed the circuit until I can alleviate the problem.

I can't think of a reason not to. As long as it's just like it was originally, it seems fine.

Could not thread the sheath through the access hole. Scrapped that idea and went back to square one and used a clamp. Only took 'bout an hour and half. Amazing when you do things over how much quicker things go.

Thanks for all the advice. Now maybe my house won't burn down. Ha!

I just love this site and those who participate!

:clap: Hip Hip Hooray for doing it right, even if it wasn't the first time. It's how we learn, after all. :thumbup:

Inductive heating of the insulation? The only time inductive heating is an issue is if there is a ferrous material between the conductors. Otherwise, you can separate them as much as you want without a heating issue (see old K&T installations), but there would be a code issue. Separating conductors can cause EMI problems also.

Nice to know. Next time that should happen(no sheath) I will not worry but I do feel better with the sheath intact on the second try.:thumbsup:

I didn't say that no sheathing is fine. It is a problem. It just has nothing to do with inductive heating.

It'd be illegal, which is usually enough of a reason. Most of us just won't endorse something that "technically" works fine, but doesn't meet code. It's a liability thing, yanno?
