Shorted a wire... What next?

While installing a new vent cover for the microhood exhaust, I screwed into a 12/3 romex that supplied the fridge and microhood. Didn't even realize it till the wife asked if I turned the power off. Crap, I thought- instantly knowing what I did. The breaker had flipped. I went outside, removed the exhaust vent cover and confirmed the romex had been punctured. I wrapped it in electrical tape and reset the circuit. Everything looks ok. No flickering or breaker resetting.

What should I do? Leave it? Cut the wire and put a junction box there? Any help would be appreciated.

Yes , either replace the entire cable from source or install a Jbox at the break and replace the last part. The Jbox must remain accessable,

Youíll need about a foot of slack to be able to use a junction box properly. Does the cable have enough? You might have to fish a new cable in to replace it, at least part of it, putting a junction box in a convenient place. Any junction box will have to remain accessible.

As far as leaving it, no, you should repair/replace it properly. You donít want it to possibly start a fire.

You should have 6" of free conductor inside the junction box. The part with the damage could be part of the 6". I would repair the damage with heat shrink tubing.
