What minimum distance must be maintained from the front edge of a stud when boring for nonmetallic cable?

The correct minimum distance that must be maintained from the front edge of a stud when boring for nonmetallic cable is established to protect both the cable and the structural integrity of the stud. This distance is set at 1¼ inches.

When nonmetallic sheathed cable (often referred to as NM cable) is installed in walls, avoiding places where fasteners might penetrate the stud or where the cable could experience excessive pressure or abrasion is crucial. If the hole for the cable is too close to the edge of the stud, there is an increased risk of nail or screw penetration into the cable, which could lead to shorts, electrical failures, or fire hazards.

The National Electrical Code (NEC) provides these guidelines to ensure safe and compliant installations. Adhering to this minimum distance helps maintain safety standards and prevents damage to the wiring during construction or renovation activities.

Thus, maintaining a space of 1¼ inches from the front edge of a stud when boring for nonmetallic cable is essential for ensuring that installations are both safe and in compliance with established electrical codes.
