Good point - thanks for the correction on that Bill. So - it's just a
lesson to stick in your arsenal of information - every electrical
connection needs some sort of clamp for strain relief. From now on it's
almost a sure bet you will notice such things in existing wiring and

it's
not likely you'll make this same mistake again.

Also, he should realize that a staple holding the romex to the stud is
required within 6 inches of the box - for strain relief.

No, it's not.

12"?

Code here is within 8" ...


The 8" rule in the NEC states that when using a non-metallic box, NM cable is
not required to be secured to the *box* if it's secured to framing within 8"
of the box. Nowhere that I'm aware of does the NEC require NM cable to be
secured to framing within any particular distance of a box as a general rule;
in fact, the Code explicitly permits NM to be fished inside walls in existing
construction without being supported by or secured to the framing _at all_; of


course, if you do that, you're required to secure it to the box.


I thought NM had to be secured to the framing on new wiring. Certainly that's
not possible with old wiring.


It does. But there's not a general requirement -- not one that I'm aware of,
anyway -- to secure it within any particular distance of the box, provided
that it's secured to the box.
