12.6.3. Precautions when knocking out knockout holes
To punch a knockout hole, hit on it with a hammer.
After knocking out the holes, we recommend removing any burrs
and paint the edges and areas around the holes using repair
paint to prevent rusting.
When passing electrical wiring through the knockout holes.
prevent damage to the wires by wrapping the wiring with
protective tape, putting the wires through field supplied
protective wire conduits at that location, or install suitable field
supplied wire nipples or rubber bushings into the knockout
holes.
