Aluminum Wire Mitigation
Aluminum wire, which was commonly used in residential electrical systems in the 1960s and 1970s, can present safety concerns due to its properties. Over time, aluminum wire connections can become loose, which increases the risk of overheating and potential fire hazards. This issue is primarily due to aluminum’s higher coefficient of expansion and its tendency to oxidize. Here’s how to mitigate the risks associated with aluminum wiring:
Proper Terminations and Connections
AlumiConn Connectors: AlumiConn connectors, which is a UL-listed product specifically designed for safely connecting aluminum wire to copper or to other aluminum wire. This solution involves a technique in which a short length of copper wire is attached to the end of the aluminum wire.
This allows for the use of copper-based devices, such as outlets and switches, while minimizing the risk of aluminum wiring corrosion and connection issues.
Regular Inspection and Maintenance
Routine Checks: Aluminum wiring should be regularly inspected, especially if the house is older and the wiring hasn't been upgraded. Loose connections can lead to overheating, so ensuring connections are tight and intact can prevent potential issues.
Look for Signs of Damage: If you notice any signs of overheating (such as discoloration around outlets or switches, or warm-to-the-touch electrical components), have your aluminum wiring inspected immediately to prevent further damage or fire risks.
Avoid Overloading Circuits
Monitor Electrical Load: Aluminum wiring is more susceptible to overheating under excessive load. Avoid overloading circuits and always ensure that your wiring is suitable for the electrical needs of your home. At Shelton Electrical Services we can assess your system to ensure that circuits are not being overloaded and that wiring is adequate for current demands.
Avoid High Energy Appliance: With aluminum’s higher coefficient of expansion under load and its tendency to oxidize. It is imperative to avoid using space heaters, portable air conditioners and other appliances with extensive power draw.
Mitigating the risks of aluminum wiring requires careful attention and the implementation of proper techniques to ensure safety. Whether you choose to use specialized connectors, or take preventive steps like regular inspection, addressing aluminum wiring concerns is essential to prevent overheating and fire hazards. Always consult with us, your trusted electricians, to determine the most appropriate solution for your home’s specific electrical system.
