I wonder if every connection, in every disconnect, breaker panel, and everthing that was associated with electrical distribution, had penetrox applied to the ends of the wires before they went under the lugs, nuetral bars, or termination points would make a diffrence in the final bill. I know a few sparkys that coat the ends of the wires, to prevent oxidation and corrosion. This is done whether the panel is inside or outside. I would be interested to see this stuff in action. Does it look like penetrox?
