Field reports & photos of aluminum electrical wiring failures, overheats, fires: this article contains photo-documented reports of actual in-service aluminum wiring failures in homes.
We have been receiving reports from home owners,
builders, and building professionals since 1990. However this page was created in July 2004, so it will not contain all
of the historical data. Recent reports, photographs, anecdotes are be displayed here. When I complete statistical
analysis of prior reports I'll add that data at this page.
Aluminum Wiring Overheating Reports with failure photographs
240V Heat Pump Circuit - Aluminum Wiring Failure Case
"I was replacing the heat pump unit on our home and went under the house to wire in the new unit to an existing junction
box. Upon opening the box I let out an expletive and then went right to our local home center to purchase some new copper
wire to run from the service panel to the new unit.

Whoever wired the previous unit must have had some Al wire around but
not quite enough to reach the unit, so they used a junction box to connect Al and Cu wire. Fortunately, the so-called
technicians used a steel box otherwise the house could have burned down.
This was the only aluminum wiring I have found thus far but I'm not done inspecting yet."-- J.F. 6/30/2004
