12-2 wiring question


How many 12g wires can I put under one big red wirenut and pass code?
I find I need 4, not 3 as I had thought at first. Is 4 OK?

Thanks, just double checking!

Should say on the side of the container they came in if you have it, but 4 #12 will be fine with the red marrette.

Thanks! There WAS a little tiny chart on the plastic package. I should have looked first, sorry.....
It says 2 to 5 for #12, up to 6 for #14!! (but only 3 for #10)
Wow, I'm imagining a hard time with 4 #12s..... don't think I want to try 5.

Try 6 to 7 #10 solids and then 5 #12 would be easy for you.

The best way is to leave lots of bare copper when your stripping them, line up the jacket of the wire and slowly twist.

Yup, I got 'em in fine. It was actually a little easier than I thought it'd be.
Box finished, on to the next project!

Thanks!

Really depends on your local inspector. Four #12 is pushing it, since that is the max the Red ones take. Blues will take 4-6.

If you are good, you can get 6, not that I have ever done that!

NEC does not codify the number of wires a wire nut can take, and there doesn't appear to be an industry standard. This is one of those issues where code would say you follow manufacturers instructions. Even within a single manufacture, different style wire nuts of similar color can still have different specifications.

Very good point, thank you!

I called the inspector this morning on another matter, though I also asked on this. He said 4 is fine, though he prefers 3 with a pigtail. He also refers back to packaging specs. He says "If that's what the MFG. says is OK, I'M OK with it."

Here's a link to Ideal's catalog showing the various wire nuts with charts showing basic range of wire sizes covered by the different colors.

And for those of you who use the Ideal wire nuts, here's a great chart that basically lists every allowed wire combination for the various wire nuts. Really handy when you're mixing wire sizes such as wiring illuminaries.
