If you’re considering purchasing a home in Edmonton, particularly one built between about 1970 and 1976, there’s a detail you should be aware of: aluminum wiring. While it may not grab headlines like other home safety concerns, it is an issue that should be on your radar.
Let’s dive into what aluminum wiring is, why it can be problematic, and how it might affect your decision as a homebuyer.
What’s the Problem with Aluminum Wiring?
In the post-World War II construction boom, aluminum wire was widely used in residential homes for branch wiring due to a shortage of copper. While it seemed like a good alternative at the time, but it came with unforeseen complications.
- Oxidation: Aluminum reacts with oxygen in the air, forming aluminum oxide. This process impedes electrical conductivity, increasing resistance and heat buildup in the wiring.
- Connection Loosening: Aluminum is softer than copper and expands more significantly when heated. This expansion and contraction can cause connections to loosen over time.
- Incompatibility with Modern Fixtures: Many fixtures and connectors are designed with copper wiring in mind. Using aluminum wire can lead to improper connections if not paired with compatible components.
- Heat Generation: Loose connections and resistance from oxidation can cause excessive heat, which increases the risk of electrical fires.
Why It Matters for Homebuyers
When it comes to home safety, the wiring system plays a critical role. Here’s why it matters:
- Increased Fire Risk: The heat generated by loose connections and oxidized wiring significantly raises the potential for electrical fires.
- Higher Insurance Premiums: Many insurance companies consider aluminum wiring a liability. Homeowners with it often face higher premiums or may need to replace the wiring to obtain coverage.
- Resale Challenges: If you purchase a home with aluminum wiring, future buyers may hesitate due to the associated risks, potentially impacting resale value.
- Costly Upgrades: Addressing aluminum wire issues can be expensive, whether it involves replacing the wire entirely or installing corrective measures like COPALUM connectors (AKA Pigtailing) or Alumiconn devices.
How to Identify Aluminum Wiring
If you’re eyeing a home in Edmonton built in about 1970 to 1976, here are some steps to determine whether it has aluminum wiring:
- Check the Electrical Panel: Look for labels indicating “AL” or “ALUMINUM” in or beisde the panel the panel. This is often a clear indicator. The wire is silver in colour.
- Inspect Visible Wiring: If accessible, examine the exposed wiring in attics, basements, or crawl spaces for the aluminum label.
- Hire a Professional Home Inspector: A licensed home inspector can confirm the presence of aluminum wiring during a thorough electrical inspection.
What Can Be Done About Aluminum Wiring?
If a home has aluminum wiring, it doesn’t necessarily mean you should walk away. Here are some solutions to mitigate the risks:
- Rewire the Home: While costly, replacing aluminum wire with copper wire is the most comprehensive solution.
- Install COPALUM Connectors: These connectors are specifically designed to make aluminum wiring safe for use with modern electrical systems.
- Use Alumiconn Devices(AKA Pigtailing): A more cost-effective alternative to COPALUM connectors, these devices allow aluminum wire to connect safely to copper wire.
- Routine Inspections: Regular inspections by a licensed electrician can help identify and address potential issues early.
