good discussion on power cords

I suppose that the parts of a circuit breaker one would slather with a silver grease, might be those that grip the box’s buss bar and Romex, could escape some.

Rodman,
That type of thinking (correct BTW) only exists with those that are not trying to degrade the idea. 
Or perhaps someone heard about using silver grease on a circuit breaker and decided they would "slather" some on the connection point point to the buss-bar, not knowing that the technique is used to grease the contacts of large breakers, not the connection points of residential breakers .... likely the result also of not knowing the contact resistance of that connection to the buss-bar.

No comments , science  versus beliefs
no electrical engineer would support the  Validity of the famous claims about power cords unless he turned out to be a cable manufacturer 
3000$ power cords, 18,000 $ speaker cables? We audiophiles are the faithful ones. Science is no cure, He is preaching to the wrong crowd
Grease is required by code where I live on main feed aluminum wire. Other than that I don’t see any reason to make a mess in the box with grease. If it’s an outdoor panel a little dielectric grease might be a good idea to help against corrosion on connections. Good video in the OP though a bit long.
