In the 1970s I kept a can of grease for wire nuts and terminal connections in 120/240 VAC wiring because the National Electrical Code required it in many cases.
I didn't use this stuff, but the description is noteworthy because it points out that "conductive grease" doesn't conduct electricity... not well enough to count. One function is to conduct heat so that everything warms and cools together. The main function is to prevent corrosion. It was often required with aluminum wire and could be beneficial in other cases.
I think this is the stuff I used.
It was applied to wires before making connections. Silicone grease might have done the job, but this had zinc for additional corrosion protection. The zinc made it opaque so I could tell at a glance that I had full coverage. It was thick, which made it a better heat conductor and harder to wipe off by accident.
