The Hidden Danger of Aluminum Wiring in Oregon Homes
During the copper shortage of the mid-1960s through early 1970s, builders in Wheeler, OR 97147 and the rest of the country used aluminum wire for 15-amp and 20-amp branch circuits — the circuits that feed your outlets, switches, and light fixtures. While aluminum is an acceptable conductor for larger service entrance cables, its use in small branch circuits created a serious fire hazard that the U.S. Consumer Product Safety Commission (CPSC) later documented as being 55 times more likely to reach fire-hazard conditions than comparable copper-wired homes. If your Oregon home was built between 1965 and 1973, call (877) 883-2383 for a free aluminum wiring inspection.
The problem centers on what happens at connection points. Aluminum expands at a much greater rate than copper when it heats up from carrying electrical current. Every time a circuit is loaded, the aluminum conductor expands; when the load drops, it contracts. This constant thermal cycling gradually loosens the connections at outlets, switches, and junction boxes. Once a connection loosens, aluminum's surface rapidly forms aluminum oxide — a white, powdery compound that is a poor electrical conductor. Current forced through this oxidized, loose connection generates intense localized heat, which can ignite surrounding materials. Call (877) 883-2383 to have our licensed electricians evaluate every connection in your home using infrared thermography to identify hot spots before they become fires.
Oregon's suburban developments from the late 1960s and early 1970s — particularly in areas around Portland, Beaverton, Tigard, Salem, Eugene, and Medford — contain a high concentration of aluminum-wired homes. Many homeowners are unaware their house has aluminum wiring until an insurance inspection, a real estate transaction, or a remodeling project reveals it. Our CPSC-trained electricians perform comprehensive remediation using COPALUM crimp connections (the only method the CPSC considers a permanent repair) and AlumiConn lug connectors as an approved alternative. Call (877) 883-2383 to protect your family and your home.
Indicators of Aluminum Wiring Hazards
- Warm or discolored cover plates on outlets and switches, indicating overheating at aluminum connections behind the plate
- Flickering lights or intermittent power at specific outlets caused by loose, oxidized aluminum terminations
- Home built between 1965 and 1973 with original wiring that has never been remediated or inspected for aluminum hazards
- Insurance company flagging aluminum wiring during underwriting or requiring remediation documentation for policy renewal
- Previous repairs using standard copper wire nuts on aluminum-to-copper connections — a code violation that worsens the fire risk
- Burning smell from outlets, sparking when plugging in devices, or melted plastic on receptacles — call (877) 883-2383 immediately.
