What is a key requirement when routing conductors through framing members to prevent contact with nails or sharp edges?

• A. Use protective bushings or conduit and maintain spacing.
• B. Drill large holes without guards.
• C. Wrap with tape only.
• D. Expose to nails for easier installation.

Answer: (A)

Protecting conductors from nails and sharp edges is essential whenever a wire passes through framing members. The safe and code-compliant approach is to shield the portion of the cable that runs near the edge with protective hardware such as nail plates (protective bushings) or to run the conductor through conduit, and to maintain adequate spacing from the edge of the framing member. This combination prevents nails or screws from puncturing the insulation if the framing is later nailed or screwed, and it reduces the risk of damage from sharp edges or sharp-edged holes. If the bore is too close to the edge, a nail plate must be added to shield the wire; otherwise, the wiring is vulnerable. The other options fail because they do not provide real protection or necessary clearance: drilling without guards offers no barrier against nails; wrapping with tape provides negligible mechanical protection; and exposing the conductor to nails defeats safety and code requirements.
