- Tighten set screws to the torque indicated below, based on conductor size and material as indicated.
What is the correct way to connect copper to aluminum wire?
Both solve the problem of connecting two different metals which normally cannot be done directly. You need to apply special contact paste to aluminum wires before inserting them into connector.
How do you connect copper wire to aluminum?
Pigtailing aluminum wiring entails splicing a short length of copper wire to aluminum wire and then connect the copper wire to the electrical device approved for copper connection. The proper connectors must be used – approved for copper to aluminum connections – and antioxidant compounds.

They are also flexible as they can be used for aluminum to copper, aluminum to aluminum, and copper to copper connections. Another benefit is its resistance to rust, for longer lasting connections.
What happens when you mix copper and aluminum?
When copper and aluminum are heated to 550 degrees Celsius (1,022 degrees Fahrenheit), solid copper will dissolve in the aluminum, forming a solution. At this temperature, the copper-aluminum solution can contain up to 5.6 percent copper by weight. This solution is saturated; it can hold no more copper.
