It was not called on older breakers, only recently Siemens tarted putting this stuff in.
Was not it needed, not called before, does it has to be addd on previosuly bought breakers???
Conductive grease is GOOD. Any place where there is dubious contact, is an opportunity for heating and burning.
Lord knows that the old Zinsco trash was infamous for having contacts in the breakers that did not grab the buss bars for squat. In the event that I am called out on a dodgy Zinsco panel, and it is common enough, I likely will find a breakers that has not been making reliable contact to the buss bar and is arcing. Assuming that the client will not face up to the cost of a re-panel, often all I can do is clean up the buss bar, replace the breaker, and apply a generous dose of conductive grease.
Admittedly, there are situations where too much of a good thing is the case.

Theory only works perfect in a vacuum.
I used Noalox in a couple of places recently (main lugs on my new service). After watching the video, I'm having real doubts about the stuff. Not really worried, since the actual amount is very small and everything was torqued correctly...
Once again, JW, thanks for sharing your knowledge and experience.
I just had my home telephone box replaced, and the ATT tech said that all their connectors come greased now.
A spot the size of a BB along with an arc and then all …… well you know what is fixing to break lose
Vaseline soaped cotton balls are a great camp fire starter
