Requirements for a splice in a junction box

WillK

I need to splice a wire in a junction box... A cable run turned out a little short. At the point where I can easily place the junction box, I'd get 3 or 4 inches of cable inside the box. I know 6 inches is what you're supposed to have. Is this a code requirement, or will the 3 inches be okay?

Code requires 6 inches.

Pigtail some more wire on for the extra length needed

Maybe I kept the post short to keep it simple, but that made me LOL a bit... So in order to comply with code, to make up the extra 2' I need to reach my circuit breaker, I would splice inside a junction box into which I can only get 3 inches of the cable that was too short, to make the 3 inches get to the required 6" I could splice another 3" inside this junction box, so now I have 3 wires spliced together?

All of this is to avoid having to buy more 14-2 cable since I don't have enough to do the whole run. Now it's just sounding silly, I'm leaning towards replacing it with 12-2 cable which I have enough to spare (Just bought my second 250' roll, and I expect to need around 115' of it)

Replacing the _entire_ circuit w/12-2? If not, make sure you mark that 12-2 as being in a 14-2 circuit so no one ever runs 20A over it.

It's a dedicated circuit for the dishwasher, I cut off a piece at 25' approximately before pulling it through and it turns out I needed 27-28 feet.

Just rerun!

A splice to make it 6 inches is not to code. The wire needs to be 6 inches when installed in the box to be code.
