Is this okay?

I've read and seen in videos to leave a little extra outside the box in case of rewires or other unforeseen circumstances. Just seems a little off to me.

Thanks

How much did you leave inside the box?

There's about a half inch of sheathed cable in the box and then about 6 inches of unsheathed wires.

No. The cable is required to be secured within 12" of the box. This is measured along the length of cable, not the distance from the box. I have never found a need to leave slack inside the wall.

Also, you need to keep the cable 1 1/4" away the nailing face of the stud. The cable on the inside hole is too close to the face on the back side with the wood sheathing.

Makes sense regarding the extra cable.

I dont understand how to fix the spacing issue you brought up. Could you please explain the remedy there?

Thanks

I guess I need to run both cables into the outside hole like in this picture?

If so, does it matter that the inside hole is punched out with nothing running into it or should I use a new blue box?

You can run one cable from each hole. Just stack them and bring them both to the center of the stud for fastening.

Correct. That is how the inspectors around here, and I, like it done.

They/I do not like how PJ shows because the hole next to the stud brings the cable closer then 1 1/4" to the back side of the stud face. This is especially true when working on a interior room wall where there will be drywall on both sides. Inspectors around me do not care about an extra hole in a plastic box being removed as there is no way to seal it, although a new box it pretty darn cheap! Your inspector may be different.

I am completely lost. Both holes are the identical distance from the front and or rear sheetrock surface. One hole is closer to the stud and one isn't.

Do you mean the cable is closer to the stud the box is mounted on ?
Your concern is if they put a nail in and miss the stud ?

No, they are not. The hole that is next to the stud is very close to the back side face, the side opposite of the box opening side. It will bring the cable closer then 1 1/4" to that face. This is only when you have a 2x4 wall that will have something (drywall, sheathing, etc) attached to both faces of the 2x4. This is not an issue with 2x6 wall, or a 2x4 wall that is put up along a concrete wall.

Correct.

Correct. That is why the 1 1/4" rule for NM cable.

I have never meet an inspector that interprets this the same was as Scott has to deal with. Both holes can be used in my experience.

Same here.... that's why I wasn't sure what we were discussing. I can see the point though.

It is especially true when using the biggest plastic boxes. 22.5 Cu In.

Even the back of the box would violate the 1.25 inches clearance.

Yes, but there is no rule in the NEC saying a box is required to be 1 1/4" away from the face, only cables.
