Many homeowners may be unaware of the dangers associated with something that lurks behind their walls – aluminum wiring. In this article, we review how this type of wiring works, how to check if you have aluminum wiring in your house, and how to update aluminum wiring.

What is Aluminum Wiring?

Aluminum wiring gained popularity in the 1960s and was considered an ideal alternative to high-priced copper wiring. The flaws associated with aluminum wiring and subsequent safety hazards it posed soon became evident, however.

One of the biggest problems with aluminum wiring is that its continued expansion over time exposes connections to air, which causes the connections to heat up and become fire hazards. Not only is aluminum wiring extremely unsafe, but many insurance companies refuse to provide coverage for homes built with aluminum wiring. The safest option for homeowners is to ensure they don’t have aluminum wiring behind their walls.

Here is how to identify aluminum wiring in your home: call a licensed electrician who will complete a thorough inspection of your wiring system. When the electrician inspects your electrical panel or exposed wires, the following markings will be evident on the outer covering if the wiring is aluminum:

  • ALUM
  • AL

How Does Aluminum Wiring Work?

When it was introduced, aluminum wiring was considered an inexpensive and effective way to provide electricity to homes and buildings. It works in the same way that copper wiring does, but has several drawbacks.

Aluminum breaks down and oxidizes much quicker than copper does, leading to increased fire hazards. Furthermore, when electrical currents pass through aluminum, they cause excessive vibration. This vibration results in a greater likelihood that connections will break down and increase the risk of fire.

These concerns, along with several other drawbacks associated with using aluminum wiring, clearly confirm this type of wiring is a safety hazard and should not be present in homes.

When Should you Call an Electrician?

If your home was built in the 1960s or 1970s or you suspect it was wired using aluminum, you should contact a licensed electrician who can confirm whether the hazard exists in your home.

Other telltale warning signs may indicate your home has aluminum wiring. Hot outlets or faceplates, smoke or a burning smell near receptacles, flickering lights, or static on the television can be indicators of aluminum wiring and should be checked by an electrician.

What can you do to Maintain Aluminum Wiring?

Some homeowners may prefer to keep their aluminum wiring instead of having it replaced. The best and safest way to maintain aluminum wiring is to ensure it is inspected by an electrician regularly – every five years at a minimum. If there are any problems with the wiring, the electrician can detect and fix the problems before they pose a fire risk.
