I need to brief a group of tranees on the importants of following T.O.
33-1-32 "General Instructions for the Input Power and Wiring of
Electrical/Electronic Equipment".  I am looking for two main subjects.
 Why it is important to follow a procedure laid out and why it is
important to follow this procedure.

Could you clarify this question a bit? It currently reads as though
you're asking the same question twice.

The general answer to the one question I can see here is that failure
to follow the instructions in this TO can result in damage or or
destruction of Air Force property, and may even result in injury or
death to the personnel involved, both as maintainers and as users of
the equipment in question.

Of course, such results could cause the maintainer to suffer a wide
variety of penalties, including but not limited to administrative
action and/or court martial.
