What’s the name of that little gadget for connecting electrical wires? Can it connect copper and aluminum wires?
These small devices are usually called copper-aluminum transition terminals, and are mainly used to safely connect copper and aluminum wires, avoiding oxidation, overheating, and poor contact caused by direct contact. They are more reliable and suitable for long-term use than simply twisting the copper and aluminum wires together.
