When boring holes in wood members for cable installation, the edge of the hole must be at least how far from the nearest edge of the wood member?

When boring holes in wood members for cable installation, the requirement that the edge of the hole must be at least 1 and 1/4 inches from the nearest edge of the wood member helps ensure structural integrity and safety. This distance mitigates the risk of compromising the strength of the wood, which could occur if the holes are too close to the edge.

Keeping this minimum distance also aids in preventing damage to the wiring itself, as the edges of the wood can become rough when cut. A buffer of 1 and 1/4 inches protects the cable from potential fraying or exposure to harsh conditions that may occur if the hole were drilled too close to the edge, ensuring that the installation meets safety codes and regulations for electrical work, particularly in New York City where specific local laws govern electrical installations.

In contrast, other options present varying distances that do not align with the established minimum depth for structural support and safety. Distances that are either too small or significantly larger do not provide the balance required for effective cable installation without jeopardizing the integrity of the wood member.
