CPSC links it to overheated connections at outlets and switches. If a home you own or want to buy may have it, ask a licensed electrician to inspect before you decide. Panels and wiringPublished July 13, 20264 min read ## What is aluminum wiring, and why does it matter? Aluminum wiring is branch-circuit wire made of aluminum instead of copper. It matters because the U.S. Consumer Product Safety Commission (CPSC) has investigated fire hazards tied to it. The CPSC testified about fire hazards in “residential aluminum wiring systems manufactured between 1965 and 1973.” Branch circuits are the wires that feed outlets, switches, and lights in your rooms. This is different from the large service wires that bring power to the home. If your house is from that era, [aluminum wiring](https://danielelectric.multisites.ai/glossary/aluminum-wiring) is a fair question to ask. Most newer homes use [copper wiring](https://danielelectric.multisites.ai/glossary/copper-wiring). ## How can you tell if a home may have it? Age is the first clue, and an inspection is the only sure answer. Do not open outlets, switch boxes, or the panel to look. That is work for a licensed electrician. Clue What it means What to do Home built in the 1960s or early 1970s Falls in the period CPSC studied Ask for an electrical inspection Seller disclosure or listing mentions aluminum The wire type is already known Get an electrician’s written review Wire marked “aluminum” or “AL” at the panel Aluminum may be present Do not touch. Call a licensed electrician Warm outlets, flickering lights, dead circuits See warning signs below Stop using the circuit and call ### What are the warning signs? CPSC lists these signs: “warm-to-the-touch face plates on outlets or switches, flickering lights, circuits that don’t work, or the smell of burning plastics.” These can indicate a fire hazard in 15 and 20 ampere aluminum wiring circuits. Smoke or sparks are an emergency. Leave the area and call 911. The same signs can come from other causes, so do not guess. Our guide to [electrical warning signs](https://danielelectric.multisites.ai/guides/electrical-warning-signs) explains the full list. ## Why do the connections cause the problem? The hazard is at the connection points. CPSC’s 2003 release said the hazard is a failing connection, and the agency has named repair systems that make connections safer. A connection that loosens or heats can arc, and an [arc fault](https://danielelectric.multisites.ai/glossary/arc-fault) can start a fire inside a wall before anyone sees it. A loose or overheated connection can also trip a breaker or make a light flicker. If you see those problems on an older home, read our post on [why a breaker keeps tripping](https://danielelectric.multisites.ai/blog/breaker-keeps-tripping). ## What are the repair options? Repair options depend on the home, and a licensed electrician must choose and perform them. Common approaches in general terms include replacing the aluminum branch wiring with copper, or installing approved connectors at outlets and switches. A [pigtail](https://danielelectric.multisites.ai/glossary/pigtail) is a short wire used to join two wires to a device, and it is part of how some repairs are made. Do not try a fix with wire nuts or tape from a hardware store. Incorrect splices can make the problem worse. CPSC’s 2003 release called its recommended crimp system the only method it recognized as a complete and permanent repair. Ask an electrician which methods meet current local rules and the manufacturer’s directions. ## What should a buyer or seller do? Buyers should add an electrical inspection by a licensed electrician to the due diligence list. Sellers who know about aluminum wiring should have a written electrician’s review ready. Our post on [electrical checks when buying or selling a house](https://danielelectric.multisites.ai/blog/electrical-checks-buying-selling-house) lists what else to check. For related older-home problems, see our guide to [Federal Pacific panels and aluminum wiring](https://danielelectric.multisites.ai/guides/federal-pacific-panels-and-aluminum-wiring). It explains the breaker panel side of the same era. ## Does a home need a permit for the repair? It can. Rules differ by city, and the city office decides. A licensed electrician in your area knows when a permit and an inspection apply. Read our Southlake permit post and Grapevine permit post for examples. Ask for the permit number on any wiring job. ## What questions should I ask the electrician? Bring a short list to the inspection. Clear questions lead to clear answers you can use in a purchase or a repair decision. 1. Does this home have aluminum branch wiring, and on which circuits? 2. Do the outlets, switches, and fixtures show signs of heat or loose connections? 3. Which repair methods fit this home, and which does the electrician recommend? 4. Will the work need a permit and an inspection in this city? 5. What is the written quote, and what does it include? Ask the electrician to explain the answers in plain terms. Keep the written report. If you are buying, it can support a request for repairs or a different price. If you are selling, it shows that you took the issue seriously. ## What should you not do? Do not add new outlets, switches, or fixtures to aluminum circuits yourself. Do not swap devices without knowing what is behind them. Do not assume a home is fine because the lights work today. A problem connection can look normal until it overheats. When in doubt, stop and call a licensed electrician. ## Next step Daniel Electric lists licensed residential work on its [residential electrician](https://danielelectric.multisites.ai/electrician) page.

Homes built in the 1960s and early 1970s are the ones to question. The wire insulation may be marked with the word aluminum or the letters AL. Do not open outlets or the panel yourself. A licensed electrician can confirm the wire type safely during an inspection. ### Is aluminum wiring always a fire hazard? No. The hazard CPSC describes is at the connections, where aluminum wire can overheat at outlets and switches. That is why the connections matter more than the wire itself. A licensed electrician can tell you whether yours show signs of trouble and which repair methods fit your home. ### Should I buy a house that has aluminum wiring? It is your decision, and it is worth getting facts first. Ask for an electrical inspection by a licensed electrician before the option period ends. Ask what repair methods apply and get a written quote. Then you can weigh the work against the price of the home. ## Terms on this page - [Electrical inspection](https://danielelectric.multisites.ai/glossary/electrical-inspection) - [Flickering lights](https://danielelectric.multisites.ai/glossary/flickering-lights) - [Aluminum wiring](https://danielelectric.multisites.ai/glossary/aluminum-wiring) - [Breaker panel](https://danielelectric.multisites.ai/glossary/breaker-panel) - [Copper wiring](https://danielelectric.multisites.ai/glossary/copper-wiring) - [Arc fault](https://danielelectric.multisites.ai/glossary/arc-fault) - [Tripping](https://danielelectric.multisites.ai/glossary/tripping) - [Pigtail](https://danielelectric.multisites.ai/glossary/pigtail) ## Sources 1.
