Can copper and aluminum wire be connected together?
Luckily, you’ll be able to splice copper and aluminum wires together without violating any electrical codes. To do this, you’ll need to use a connector that is rated for an AL/CU connection, such as the IDEAL Twister connector.
Is it OK to splice copper and aluminum wire together?
As long as the two are kept separate, this is not an issue. However, if copper and aluminum wiring are joined together using a simple twist-on splice, that presents an extra hazard because of their differing diameters and differing rates of expansion when heated and cooled.
What is the correct way to connect copper to aluminum wire?

What happens when you mix copper and aluminum?
Solid Solution
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.

Do they make GFCI outlets for aluminum wiring?
Aluminum wires are better in electrical distribution and transmission. However, typical household wiring devices (GFCI, receptacle outlets, light switches, etc.) are not rated for aluminum wire.
How do you pigtail 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.
What if my house has aluminum wiring?
The aluminum wiring installed in homes during the 1960s and 1970s is considered a serious fire hazard. Problems with installation, outlet connections, and the metal itself resulted in wiring that degrades and loosens over time. If your home has aluminum wiring, you should repair or replace it right away.
What kind of outlet do I need for aluminum wiring?
Usually, receptacles approved for aluminum wiring will get stamped CO/ALR, CU-AL, or AL-CU, indicating they may get used for both copper and aluminum. More modern “decora” switches and outlets are not aluminum wire rated. Do not use outlets marked with AL and a line through it.
Can you make aluminum wiring safe?
The most common method of solving aluminum wiring problems is the aluminum wiring pigtail option. Electrical Safety Authority Approved copper pigtailing remains the most commonly used method to make aluminum wiring safe.
Do you need special switches for aluminum wiring?
Aluminum wiring is safe if properly installed.
Use only CO/ALR wall switches and outlets. If your home has aluminum wiring and you need to replace a switch or outlet, the replacement should be a type that is specifically approved for use with aluminum wiring.
Is there a special light switch for aluminum wiring?
Use CO/ALR switches/receptacles: these are specifically designed for aluminum wire. They have “CO/ALR” stamped on them somewhere. When you connect the wire, use a paste like Noalox (box stores sell it).
