Aluminum wiring is a probable fire hazard because of problems regarding expansion, micro-fretting and arcing at connectors, which can cause overheating at connections between the wire, devices, or at the aluminum wire splices. As current increases, the connection becomes warmer through wires. The expansion of the aluminum, confined under a screw terminal, generates immense pressure that allows the metal to flow into empty spaces in the connector. When the electrical load is removed, the aluminum cools and contracts before a gap forms between the wire and connector. After that, the slightly loose-fitting connection has a much higher resistance, and corrosion may start to form in the gaps. This corrosion then further increases resistance. That resistance can create long term problems for you as a homeowner.
Aluminum wiring is mostly thought to have a useful life span of around 30 years, and the wiring connections can become hot enough to start a fire without ever causing the circuit breaker to trip. Electrical wiring repair may be necessary to fix many of the symptoms that are caused by aluminum wiring.
