Aluminum wiring was commonly used in the 1960s and 1970s as a less expensive alternative to copper wiring. Approximately 2 million homes in Canada are estimated to have aluminum wiring. However, Aluminium wiring poses many dangers in comparison to copper wiring.
Dangers of Aluminum Wiring
1. Overheating and Fire Hazards
One of the most significant dangers of aluminum wiring is the tendency to overheat and cause fires. Aluminum has a higher expansion and contraction rate than copper, which can cause connections to loosen up over time. Loose connections can generate heat, leading to overheating and electrical fires.
2. Corrosion
Aluminum is susceptible to corrosion when it comes into contact with other metals (galvanic corrosion). Galvanic corrosion leads to overheating, electrical failures, and a potential fire hazard, especially in homes with mixed copper and aluminum wiring.
3. Incompatibility with Modern Electrical Devices
To avoid poor connections and overheating, homeowners with aluminum wiring often need special connectors and devices specifically designed to work with aluminum wiring. Aluminum wiring is incompatible with modern electrical appliances, including switches, outlets, and fixtures.
4. Coverage and Resale Issues
Insurance companies may require homeowners with aluminum wiring to pay higher premiums or even refuse to cover them. Additionally, homes with aluminum wiring may be more challenging to sell, as potential buyers may be hesitant because of the safety hazards associated with aluminum wiring.
5. Challenges with Repairs and Servicing
Due to its tendency to rust and loosen connections, much more goes into aluminum wiring repairs. It often requires specialized tools that may only be readily available to some electricians. Additionally, repairs to aluminum wiring may require the replacement of entire sections of wiring, which can be costly and time-consuming.
6. Risk of Electrictrical Shock
Aluminum wiring also poses a potential electrical shock hazard. The loose connections and overheating that can occur with aluminum wiring can cause the wire to come into contact with other metal components, leading to a potential electrical shock.
Solution
Have a qualified electrician from A to Z Electrical Services inspect your electrical system. An electrician may install copper pigtails to connect the aluminum wiring to the new copper wiring. Note that these connectors are a temporary solution and should only be used until the system is retrofitted with copper wiring.
