Correct answer to question 6012
- D: 1 1/4 in
Explanation
Holes in wood framing must be bored so the edge of the hole is at least 1 1/4 in from the nearest edge of the member. If that distance cannot be kept, the cable must be protected by a steel plate or sleeve. See 300.4 in NEC 2020 and 2023 (300.6 in NEC 2026).
