Masterful Instructions
Begin the protection audit by accessing the attic, crawlspace, or basement where electrical branch circuits transition from the horizontal floor or ceiling joists into vertical wall cavities; use a high-lumen flashlight to identify every location where a hole has been drilled through the center of a structural member for wire passage; measure the distance from the edge of the hole to the face of the wood using a small ruler or tape measure; verify that any hole located less than 1.25 inches from the edge of the framing is protected by a 1/16-inch thick galvanized steel nail plate or shield plate to prevent accidental penetration by drywall screws or finish nails; look specifically for nicked or chafed wire insulation near the entry points where the Romex or BX cable may have been pulled too tightly against the raw wood edges; examine the top plates of interior partition walls from the attic side to ensure that large multi-wire penetrations are centered and shielded on both sides of the timber; check for missing or dislodged plates that may have been knocked loose during plumbing or HVAC retrofits; inspect the stud-to-sole-plate junction in the crawlspace for similar shielding where wires rise into the wall assembly; finalize the audit by ensuring every plate is secured with its integral prongs or clinch-nails and sits flush against the framing to allow for a smooth drywall finish.
If you find a spot where you can't fit a standard nail plate because the hole was drilled too close to a corner, use a Caddy-style wrap-around shield; these are designed to clip onto the wire itself and provide 360-degree protection even when the framing doesn't allow for a flat plate.
