Aluminum Wire Repairs
Between 1960 and 1980, aluminum wire was used extensively in residential building applications as a cheaper option than copper. Although the physical wire itself that runs through your walls and ceilings is safe, the termination points, if not treated, can be a serious fire hazard.
Is aluminum wiring dangerous?
FACT: Homes with aluminum wiring are 55x more likely to reach fire conditions than homes wired with copper.
Aluminum wiring can be dangerous if not properly maintained. Aluminum is soft, brittle and prone to oxidation and all of these conditions can create fire conditions. Remember, you need a healthy electrical system to power all of the electronics you use every day. We know that aluminum degrades over time so failing to treat this system can result in dangerously harming your wires.
What are the issues with aluminum wiring?
Reported problems with aluminum wiring are related to the failure of the terminations due to overheating. Overheating is typically caused by the aluminum’s tendency to oxidize and its incompatibility with wiring devices that are not rated for aluminum wiring. It also has a high degree of thermal expansion meaning that it swells when it’s hot and contracts when it’s cool. This expansion and contraction, at the termination point, can cause it to loosen up over time. Both the thermal expansion and oxidization result in higher resistance and higher resistance = heat.
The first step is knowing if you have aluminum wiring. You can sometimes identify the wire type on the insulation of the wires at the panel, or by taking off of a cover plate and looking into the box of a wiring device within the home. Always consult a licensed electrical contractor before tampering with your electrical wiring.
Some of the common warning signs that you have failing aluminum terminations are:
Warm receptacles, switches or cover plates
Discolouration of receptacles, switches or cover plates
The smell of burning plastic
Dispelling any myths about aluminum wiring and the steps necessary to ensure your safety:
The most common misconception is that you need to completely remove the wiring from behind the walls of your home and replace it with copper. Again, there are no issues with the integrity of the wire itself. Where we see the majority of the issues is where the aluminum makes a termination or connection to a device. The second most common myth is that aluminum wiring was recalled and is no longer used for interior wiring. The fact is that the Ontario Electrical Safety Code permits the installation of aluminum so long as adequate precautions are given to the terminating and splicing of the conductors.
If you have aluminum wiring and are looking to have the connection points at your devices treated or pig tailed, call us today and our electrical solution team will advise you on how to approach and remedy the termination points within you home. Your insurance may also be charging you a premium for living in a home with aluminum wiring. Only a licensed electrical contractor like HOME SAFE, in conjunction with the Electrical Safety Authority, can provide you with the necessary certiﬁcate, stating that the work has been completed to satisfy code and best safety practices.
