Question

Quizplus · Accepted Answer

Listed bushings (or grommets) are the best choice for protecting nonmetallic-sheathed cable passing through holes or slots in metal framing, as they provide a protective barrier between the cable and the sharp metal edges. Plastic covers, electrical tape, and rubber inserts may also provide some protection, but they are not specifically designed for this purpose and may not be as effective or safe.
