What does the box/packaging state for cable size. When you use staples, they only need to be in far enough that it keeps the cable from hanging loose against the stud. More so for securing the romex, so that the drywallers do not pinch a loose cable when hanging the drywall, and also to secure at the junction box to keep the cable from being pulled out of the box.
Seems like a silly question I guess...I suppose a 10/3 is a lot wider than 14/2 and that is where the extra width comes in? I just saw 3/4" and grabbed them thinking I would have enough nail for stacking 2 cables.
