What is the area of 12-2, and 14-2 romex?
Answers: Unless amended by a state or local code, in that is no maximum fill for holes within studs in the National Electric Code. But merely two under a staple and two surrounded by a romex connector. Cables such as romex are not rated by nouns as are single conductors.
