Long Alumina

Question regarding copper & aluminum wiring?

Okay, so aluminum wires oxidizes when exposed to air long enough, and the alumina oxide is highly resistive- so connections to terminals on switches are prone to heating up and melting. This effect is compounded when accelerated by copper and aluminum conductors being mated.

The screws that hold the wires into the bus bar make an excellent mechanical connection that is almost vibration & thermal expansion-proof. The set screws are specially designed to dig into the metal to make a long-lasting electrical connection that resists oxidation.

Its the copper to aluminum wire connectors and the outlets that have aluminum wire plugged in, or screwed on that you have to worry about.
