Aluminum Wiring

aluminum wiring gone bad Aluminum wiring, used in some homes from the mid 1960's to the early 1970's, is a potential fire hazard. This photo shows what happens when aluminum wiring is connected in the wrong manner. Not fun!

How safe is aluminum wiring?

According to the Canadian Consumer Product Safety Commission, fires and even deaths have been reported to have been caused by this hazard. Problems due to expansion, or more likely micro-fretting and arcing at the connectors, can cause overheating at connections between the wire and devices (switches and outlets), or at splices. The connections can become hot enough to start a fire without ever tripping a circuit breaker. Stack Electric has the experience and know-how to safely handle your aluminum wiring needs.

Research shows that homes wired with aluminum wire manufactured before 1972 are 55 times more likely to have one or more connections reach "Fire Hazard Conditions", than homes wired with copper. Post 1972, aluminum wire is also a concern. Introduction of aluminum wire "alloys" in 1972 did not solve most of the connection failure problems.

Aluminum wiring is still permitted and used for certain applications, including residential service entrance wiring and single-purpose higher amperage circuits such as 240 volt air conditioning or electric range circuits. The fire risk from single purpose circuits is much less than for branch circuits.

But it's not necessarily because of a "new alloy" as some folks think. It’s because there are enormously fewer connections (four or six rather than 30 or 40 per circuit) and thus, statistically, a smaller chance of a connection failure. These connections do still burn up, as indicated by field reports.

What Our Clients Say

We got great news today from our new home insurance broker: our place now meets all of their strict requirements for full coverage. Thanks in large part to the top-notch work performed by Kevin and Tracie at STACK ELECTRIC. Our previous insurer demanded a total upgrade of our 40-year-old aluminum wiring system, so I desperately called several contractors. Kevin answered in about four minutes, calmed my nerves and arrived that same Friday afternoon. He and Tracie easily assessed our situation and presented a very reasonable quote for a 1.5 day job. Monday morning they began their thorough mission to pig-tail every switch, receptacle and fixture that needed upgrade. They also repaired or replaced several that had been previously mis-installed. Throughout the project they took time to explain their procedures and make recommendations where necessary. All done with much appreciated re-assurance, and dazzling sense of humour. Their clear professional ELECTRICAL INSPECTION REPORT was instantly accepted by our home insurer. On time, on budget, mission accomplished – what else could we ask for?
