- 1.5 inches from the nearest edge
- 2 inches from the nearest edge
- 1 inch from the nearest edge
- 1.25 inches from the nearest edge (Correct answer)
Correct answer: 1.25 inches from the nearest edge
NEC 300.4(A)(1) requires cable or raceway to be at least 1.25 inches from the edge of a wood framing member to protect against nail or screw damage.
