Aluminum wiring in home is an electrical wiring commonly used from the 1960s to the mid-1970s. It was initially considered a cheaper and lighter alternative to copper wiring, which was standard.
However, aluminum wiring is now recognized as posing significant safety risks due to its tendency to expand and contract with temperature changes, which can cause the wiring to become loose and create a fire hazard.
Additionally, aluminum wiring is more prone to corrosion than copper wiring, which can further increase the risk of fire. If you suspect that your home has aluminum wiring, it is important to have it inspected by a licensed electrician.
Is aluminum wiring in home dangerous?
Aluminum wiring can be dangerous if it is not installed or maintained properly. One of the main concerns with aluminum wiring is that it can expand and contract with temperature changes, which can cause the wiring to become loose and create a fire hazard.

Aluminum wiring is more prone to corrosion than copper wiring, which can further increase the fire risk. However, if the wiring is installed correctly and regularly inspected by a licensed electrician, the risk of danger can be significantly reduced.
If you suspect that your home has aluminum wiring, it is important to have it inspected by a licensed electrician to ensure it is safe.
How do I know if I have aluminum wiring in my home?
If your home was built between the 1960s and mid-1970s, there is a possibility that it contains aluminum wiring. To determine if your home has aluminum wiring, you can hire a licensed electrician to inspect. They can check the wiring connections and determine the type of wiring that is present in your home.
You can also look for some signs that may indicate the presence of aluminum wiring, such as:
Labels: Look for labels or markings on the electrical panel or the wires that indicate that the wiring is aluminum.
Color coding: Aluminum wiring is typically silver or gray, whereas copper wiring is typically copper-colored.
Outlets and switches: If the outlets and switches in your home are warm to the touch, discolored, or show signs of melting, this may indicate aluminum wiring.
Flickering lights: If your lights flicker or dim frequently, this may be a sign of loose connections caused by aluminum wiring.
Aluminum wiring can cause fires in homes for several reasons:
Expansion and contraction: Aluminum wiring expands and contracts more than copper wiring with temperature changes. This can cause the wiring to become loose at the connections, which can create a fire hazard.
Oxidation: Aluminum wiring is more prone to oxidation than copper wiring, which can cause it to corrode over time. Corrosion can create loose connections and a fire hazard.
Softness: Aluminum wiring is softer than copper wiring, which can cause it to be easily damaged or nicked during installation or maintenance. This can lead to a break in the wire or a short circuit, which can create a fire hazard.
Mismatched connections: Aluminum wiring should only be used with devices that are specifically designed for use with aluminum wiring. For example, if copper-only devices are used with aluminum wiring, it can create a mismatched connection that can become a fire hazard.
It is important to have your home’s electrical system inspected regularly by a licensed electrician to ensure that any potential fire hazards related to aluminum wiring are identified and addressed promptly.
How do I make the wiring in my home safe?
The safest way to address the potential hazards associated with aluminum wiring is to have it replaced with copper wiring by a licensed electrician. This involves rewiring the entire house, which can be expensive and time-consuming, but it is the most effective way to ensure the safety of your home’s electrical system.
However, some temporary solutions can be implemented to make the aluminum wiring safer:
Aluminum wiring can be appropriately terminated: Aluminum wiring should be terminated correctly to prevent it from becoming loose, which can cause a fire hazard. A licensed electrician can install special connectors called “copal-um” crimps or “alumiconn” connectors that can be used to properly terminate the aluminum wiring to copper pigtails, which can then be connected to the switches and outlets in your home.
Regular electrical inspections: Regular electrical inspections by a licensed electrician can identify any potential issues with your home’s electrical system, including those related to aluminum wiring. This can help catch any problems before they become a safety hazard.
Avoid DIY electrical work: If you have aluminum wiring in your home, it is important to avoid any DIY electrical work. Only licensed electricians should work on your home’s electrical system to ensure that it is safe and up to code.
Overall, the safest way to address the potential hazards associated with aluminum wiring is to have it replaced with copper wiring by a licensed electrician.
What permits do I need?
In British Columbia, a homeowner will typically need to obtain a permit from the local municipality or jurisdiction before replacing aluminum wiring in the home. The type of permit required will depend on the scope of the work being done.
