Wiring closer than how many inches to the front of a stud should have protection?

Wiring that is closer than 1-1/4 inches to the front of a stud should have protection to prevent physical damage. This requirement is in place because electrical wiring is susceptible to damage from nails or screws that might be driven into the wall during construction or when hanging items.

When wiring is installed within walls, it is essential to protect it, particularly in areas where it is likely to be exposed to potential punctures or impacts. Installing protection such as conduit or cable armor provides a safeguard against accidental harm, ensuring the safety and functionality of the electrical system. The 1-1/4 inch standard is specifically designed to create a buffer zone, reducing the likelihood of damaging the wiring, which could lead to electrical shorts or fires.

This standard applies to non-metallic sheathed cable, which is commonly used in residential settings. It is important to adhere to these regulations to ensure compliance with electrical codes and to enhance safety in homes.
