Is there any compound that should be used on outdoor connections to prevent any oxidation or moisture from getting in to them? Mainly connections inside 3R enclosures to lugs or breakers.
I know there is NoOx for Al to Cu connections... but I have read that NoOx should not be used on non-Al connections. Something like the gel that is in the exterior blue wire nuts for outdoor use.
Or is it better to just use nothing at all on outdoor copper to panel lug/breaker connections?
