How close to the nearest edge can NMC be installed when parallel to framing members?

When considering the installation of nonmetallic sheathed cable (NMC) parallel to framing members, the code stipulates that the closest edge of the cable to any framing member should be at least 1 1/4 inches away. This requirement is designed to minimize the risk of physical damage to the cable and maintain proper electrical safety standards. Specifically, the code recognizes 1 1/4 inches as the maximum distance that ensures the cable remains adequately protected while being installed in a parallel manner to the studs or rafters. This is critical to prevent the potential for nails or screws driven into the framing members from penetrating the cable, which could lead to electrical hazards, short circuits, or fires.

To successfully adhere to electrical safety and building codes, it's essential for installers to understand these clearances to guarantee both functional performance and safety. The chosen option highlights the importance of compliance with installation guidelines to reduce risks associated with electrical installations.
