Punctured neutral wire, repairable?


Im running new 20AMP circuit to have more outlets in the garage. I currently only have one 15AMP outlet. When I was pulling the wire it got caught on a nail and ripped the sheath and part of the insulation of he neutral wire insulation. It this repairable or Im I going to have to install a junction box to splice the wiring?

I did see a product on amazon for cable jacket repair tape. http://www.amazon.com/Scotch-Cable-J...+jacket+repair

I just wanted to know what the pros would do in my case. Thanks

How bad is it?

Biggest issue to me is did you knick the copper.

If copper ok. Tape it up.

If copper not ok. Splice or replace.

Regular electric tape. Not the stuff in your link

Pull it out and re-run it again. Be a little more careful pulling it.

Do you have a preferred electrical tape for this type of repair? When I walk into the electrical aisle there are about twenty different variations it seems.

99.9% of the time just wrapping the wire and then the cable with electrical tape will be fine.
However, I would replace it. I am just not comfortable doing something so conspicuously wrong.

well the good news is the copper wasn't hit. Whats the difference between super 88 electrical tape vs the other brands? Also, what kind of effect does having a knick in the copper make? Im just curious.

The performance specs on $4 a roll tape beat the hell out of 69 cent a roll tape.
I like 3M super 33+ tape for most uses. Super 88 is 1 mil thicker, so they claim a better abrasion resistance. Either of them offer superior adhesion as compared to many tapes. They leave far less residue than cheaper tapes, if you have to remove them.

Superior installation temp range, withstand more higher operating temps, better flame resistance and UV protection, etc.

That doesn't mean you will not find other tapes that will work for what you are doing, but you asked about a preferred tape.

perform a test. Knick a piece and bend it back and forth a few times. Do the same with a clean piece.

Super 88 or 33+ are the best. Only used a couple feet when I rewired my entire house. 2000' of nm wired pulled all new fixtures and outlets. You really don't need tape when working on electical unless you have unusual circumstances.

Many many threads arguing the use of e-tape.

If it was knicked the proper thing to do in your case is pull a new cable.

Well I'd rather not run all new line so I guess I'll go ahead and splice the connection. Thanks for the info guys

Splice at a
Minimum or re-run. You could tape, save money and time, and create a real issue. Dont fool around with that

In a garage, I would think about putting in an extra receptacle rather than a junction box and splicing. It is rare to have too many receptacles in a garage.

OK, haven't seen any question about wire gauge. 15 amp circuit = 14 gauge. 20 amp requires 12 gauge.
What is your wire size currently?
