I would like to see him give me an example which shows the proper installation of these cables into a cabinet such as shown in the violation. How do I correct this? I am still unsure after seeing the video as I need to see exactly how to make the correction.

If you cut a slot between the individual holes that the cables bass through, with the cables laid out in the pattern shown in the video, it seems that the area in between the cables will fall out. So please demonstrate how this is done.

You would have to cut out a square from the box and install a aluminum or other non magnetic material of appropriate thickness to cut the entrance holes into.

There appears to be a problem with the video. The rest of my explanation at the end of the video describes how to cut away the steel and attach a non-ferrous plate (eg. brass) to to the cabinet and connect the MI cables to the brass instead of the steel. This could be done when cutting slots is not an option due to the layout of the cables.

Slotting is allowed although I do not recommend it. I believe the best way is to cut a section of the panel wall out and replace it with a fiber plate so that there is not metallic separation.
