I have been in contact with fuzztone in regard to particulars of the recommendation to use silver grease, but I thought the conversation may be important/helpful to everyone here. He warned me against using it on a breaker where a motor will be used, i.e. refrigerator, dishwasher, etc. I can also think of dehumidifier, garage door opener, etc.
In my case, I have a concern about potentially having a problem with a component that would employ a motorized volume control. I believe that my breakers to the sound equipment will be separate, but for some, their utility outlets, i.e. the ones spaced around the room for vacuum, etc. may be on the same circuit as the audio gear. Thus, putting some silver grease on the breaker could potentially cause a problem when cleaning with a vacuum?
I am conducting risk assessment of this idea, and so far it seems that the grease may dry out over time, thus the recommendation of fuzztone that the breaker be replaced every approx. 4-5yr., and the potential for issues when using a motor.
I am seeking input from my electrician, too. I do not wish to disdain fuzztone's advice, but I am going doing my own due diligence. :)
