Wiring Methods and Components - Cabinets, Boxes, and Fittings |

In addition to shock and fire hazards, conductors could be damaged if they
rub against the sharp edges where they enter cabinets, boxes, or fittings. To protect them
some type of clamp or rubber grommet must be used. The device used must close the hole
through which the conductor passes as well as provide protection from abrasion. If the conductor is in a conduit and the conduit fits tightly in the opening, additional sealing is not required. The knockouts in cabinets, boxes, and fittings should be removed only if conductors are to be run through them. However, if a knockout is missing or if there is another hole in the box, the hole or opening must be closed. |
