17.3 Guidelines when knocking out knockout holes
▪
To punch a knockout hole in a front panel, hit on it with a hammer.
▪
To punch a knockout hole in the bottom panel, drill holes where indicated.
▪
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.
