I'm not sure about "tinned" small stranded wire, but this is a known issue with aluminum building wire. Until they figured out how to fabricate connectors with set screws which were acceptable, you had to use a compression terminal (10,000 pound/sq. inch hyraulic cripper used) to attach a lug or a coupling with a copper pig tail to go on/in the switch and panel connectors. Over the years the aluminum would "flow" in a mechanical connector and become loose (I think because the coefficiant of expansion was different between the aluminum and a copper connector). In a CNC controller this loostening would cause some sparks and smoke. In the main electrical service for an office building, the sparks are bigger and you get more smoke :-)
