nicked electrical wire

I nicked an electrical wire while installing a dryer vent through a wall. Can I just wrap it with electrical tape or do I need to do more? I can see a small amount of wire but none of it is damaged. EG no cuts or fraying of the wire.

From your description it sounds like it should be replaced. Do you have a picture?

I'm not an electrician but my understanding is the outer insulation can be damaged and then repaired with tape but the inner insulation cannot - if you can see the actual metal conductor, the wire would need to be replaced.

First wrap the nick with 3M Scotchfil Electrical Insulation Putty (or comparable insulation tape), and then wrap w/ electrical tape to assure insulation stays in place.
