This Electrical breaker is so Secret its Classified ?

For years now there has always been a problem with being able to stock enough breakers on your service vehicle for service calls etc. The problem even thou breakers can interchange  from one manufacturers panel to another by code this is not permitted . Only Siemens or Bryant or Westinghouse breakers are permitted to be used in there own panels there not allowed in any one Else's even thou they fit. This is because breakers are designed to work and are listed and tested only for that manufacturers specific  panel. So you could end up carrying 100 breakers on your truck in easy fashion to try and cover all the popular brands and amperage make ups.
Well Eaton  also known as Cutler Hammer has finally come out with a breaker which can be used in multiple panels . There known as Classified Product breakers  and these breakers are permitted in more than one manufacturers panel as long as there on the approved list that Eaton furnishes with these breakers. This save's considerable time and money so now you can carry a few breakers and cover many panels and not have to run to supply house or shop to get the proper breaker.  Previous to this a company was turning out a Universal breaker which had a small white LED built into top of it  which lighted when it tripped and they claimed could be used in any panel but this was never the case and they should not have been installed,but where in many panels.
They where put in by the  thousands  in 1980's till the practice was stopped and are still out there and a potential hazard, if they where not properly matched up.
Eaton has produced an excellent video available on You Tube you can view on the subject
