How far should the hole be bored from the edge of a wood member when running cable?

When running cable through wood members, it is important to bore holes at a safe distance from the edge to prevent damage to the cable and ensure structural integrity. The commonly accepted standard for the distance to bore the hole from the edge of a wood member is 1 1/4 inches. This distance minimizes the risk of encountering nails or screws that might be used in construction and also helps to protect the cable from potential wear due to contact with the wood edges.

Boring holes at this specified distance allows flexibility in running the cable without compromising safety. When holes are bored too close to the edge, there is an increased risk of the cable being pinched or damaged and an increased likelihood of hitting fasteners, which could cause both electrical and structural issues. By adhering to the 1 1/4 inch guideline, installers can also ensure compliance with building codes and best practices in electrical installation, fostering both safety and reliability in the long run.
