What is the minimum distance from the edge of a stud that requires steel plates to protect wires during installation?

The minimum distance from the edge of a stud that requires steel plates to protect wires during installation is 1 1/2 inches. This standard is established to ensure that electrical wires, particularly low-voltage and limited-energy cables, are safeguarded from potential damage that could occur during the installation of drywall or other materials that might be attached to the framing. If wires are positioned too close to the edge of the stud, they may be at risk of being punctured or cut by nails or screws that are driven into the wall.

By maintaining a minimum distance of 1 1/2 inches from the edge of the stud, it provides a safe zone that helps prevent accidental contact or damage to the wiring, thereby promoting both safety and compliance with electrical code requirements. This regulation ensures that installations adhere to best practices in electrical safety, reducing the risk of electrical hazards over time.
