Removal of Knock Outs
1. Determine the size required.

Go across from the spot weld and apply force to break the knock out loose. Then
crimp the knock out and twist until removed.
3. Removal of the second knockout full ring.
Two spot welds located across from each other. Go 90° from each spot weld
apply force to break each side loose. Then pinch the two sides together and apply
rotating force until removed.
4. Removal of the knock out partial ring.
Go 90° from either spot weld and apply force to break the side loose. The partial
side apply force on each partial part of knock out. Pinch the three pieces together
and apply rotating force until removed.
5. Repeat step 3 and 4 until the knock out side requirements are obtained.
Conduit Entry
Drilling into enclosures for creating conduit entry locations may be required. Protect
internal components from metal fillings, via drop cloths or orientation of drilling, to
prevent foreign materials from contacting electrical connections points. An example of
a connection point is lugs, blades, or fuse clips.
Locate conduit entries to comply with bending radius requirements for conductors.
