As recommended by many sources and required by our county inspectors, I used anti-corrosive paste on any location where aluminum wires were connected. This was primarily the Service Entry and the large cable going to my basement sub-panel off a 100 amp breaker.
In reading up on the paste, I noticed it said it "decreased resistance" in the connection. If this is true, wouldn't it be a good idea to use this in other locations, especially on the high amperage cables connected to 30 amp and higher breakers for stoves, HVAC, etc., even if the cables were copper? Is it a good idea, bad idea, worth the trouble?
