A St. George electrical contractor covering residential and commercial wiring, service and repair.
Background
Houses wired between roughly 1965 and 1973 often carry aluminum branch circuits, and the problem with them is not the metal's conductivity but its behavior at the connection. Aluminum expands and contracts more than copper as a circuit heats and cools, so a terminal screw that was tight on installation slowly loosens through creep. It also forms an oxide layer that, unlike copper's, resists current rather than conducting it. The two effects compound at outlets and switches, producing heat exactly where the wire meets the device. The accepted remedies pigtail copper onto the aluminum at each termination using connectors rated for the purpose rather than replacing the devices alone.

Frequently asked questions
Why is aluminum branch wiring a concern?
Aluminum expands and contracts more than copper, so terminal connections loosen over time, and its oxide layer resists current instead of conducting it. Both effects create heat at outlets and switches. The accepted fix pigtails copper onto the aluminum at each termination with connectors rated for it.
