These connectors can be put in by any trained electrician but could require that current junction boxes get replaced with bigger ones to make room for the connectors. Oxidation has few practical implications aside from the corrosion that can happen at connection sites due to it.
Electricity is transmitted from the utility generating stations to particular person meters using almost solely aluminum wiring.
