Aluminum branch wiring installed from about 1965 to 1973 can be safe if its connections are properly repaired, but left as is it carries a higher fire risk. The CPSC found that homes with this wiring are 55 times more likely to have connections reach fire hazard conditions than copper-wired homes. The connections are the problem.
Why the connections matter
Aluminum expands and contracts more than copper as it heats and cools. Over the years, connections at outlets, switches and lights can loosen. A loose connection runs hot, and that heat can start a fire. The wire between connections is rarely the issue.
Warning signs
Warm or hot outlet or switch plates
A burning plastic smell near outlets or switches
Sparks, smoke or flickering lights
Outlets or circuits that stop working
How it is made safe
The CPSC recognizes three permanent repairs: rewiring with copper, COPALUM crimp connectors, and AlumiConn connectors at every aluminum connection in the home. All should be done by a qualified electrician. Ordinary twist-on connectors are not considered a permanent fix.
What to do
Do not open outlets or switches to look. If you think your home has aluminum wiring, call (602) 999-2770. A real person answers, and you will hear the price before anyone drives out. Our work carries a two-year warranty on labor and material.
Smoke or a burning smell from an outlet or switch: leave the area and call 911.
Common questions
How do I know if I have aluminum wiring?
You may see ALUMINUM or AL on cable in the garage or attic. An electrician can confirm without you opening anything.
Does aluminum wiring have to be removed?
No. The CPSC also recognizes COPALUM and AlumiConn connector repairs at every connection.
Is the aluminum wire to my panel a problem?
Large aluminum service and feeder wires are still used safely today. The concern is small branch circuit wiring from about 1965 to 1973.
