When installing cables or nonmetallic raceways through bored holes in wood members, what is the minimum distance that the edge of the hole should be from the nearest edge of the wood member?

The correct answer is based on the requirements outlined in the National Electrical Code (NEC), specifically regarding the installation of cables or nonmetallic raceways through bored holes in wood members. The NEC stipulates that when these installations occur, the edge of the bored hole must be a minimum of 1 1/4 inches away from the nearest edge of the wood member.

This distance is established to ensure the safety and integrity of the wood members and the wiring. If the hole is too close to the edge of the wood, there is a risk that the structural integrity of the member could be compromised. Additionally, this spacing helps to protect the cables from potential damage during installation, as well as from any future modifications or disturbances that could occur around the area where the wiring is installed.

Following this requirement minimizes the risk of electrical hazards and structural issues in the building, aligning with the overarching goal of the NEC to promote safe electrical practices.
