Project Description

Homes wired in aluminum wiring are 55 times more likely to have a fire hazard condition present than homes wired with copper.

Welcome to our Aluminum Wiring Section

Traditionally, homes built between the 1960’s and early 1970’s were wired with aluminum wiring. Then, around the mid-1970’s, aluminum wiring was labelled a fire hazard and was replaced with copper wiring. Today, only copper wiring is used in building construction.

The Dangers of Aluminum Wiring

Serious fire hazards can occur when aluminum wiring is spliced, or connects with an outlet, circuit breaker, switch, or other components of an electrical system. In addition aluminum wiring shrinks and expands, and these constant changes to the aluminum wiring can easily result in overheating, causing sparks which ultimately can lead to fires.

What can we do?

Aluminum wiring can be replaced or repaired to effectively and permanently reduce the possibility of fire and injury due to failing (overheating) wire connections and splices. It is essential that you hire a qualified electrician to perform this remediation.

What we do for you?

Other than complete replacement of aluminum wire with copper wire, there are numerous potential solutions for the permanent repair of hazardous aluminum wire connections and splices. However,the Consumer Product Safety Commission recommend repair methods or products only where there is satisfactory, documented evidence that the methods or products meet the following criteria:

  • Safe. The method or product must be safe and not increase the risk of fire or other hazards.
  • Effective. The method or product must be effective and successfully eliminate or substantially mitigate the fire hazard
  • Permanent. The method or product must affect a permanent repair. Methods or products designed to address temporary or emergency repair situations, but which may fail over time, are not considered permanent.

Based on these standards, we only use the following two methods for a permanent repair aluminum wiring

  • Complete Replacement of Copper Cable
  • AlumiConn Connector

Know the Score

It is estimated aluminum wiringthat there are over 450,000 homes in Canada that are wired entirely with aluminum wiring. Studies confirm that these homes are 55 times more likely to have a fire hazard condition present than homes wired with copper. Most of these homes were built in the 1960’s to late 1970’s. Problems began to surface where aluminum was used in branch circuit wiring. Over time aluminum tends to oxidize when exposed to air, resulting in overheating, and eventually failure at the termination points.

So, Why Is Aluminum Wiring So Dangerous?

Aluminum wiring is not as resilient as copper and also has a higher rate of expansion, which can cause loose terminations and connections, resulting in possible arcing, melting and even fire. Breakage, due to improper stripping of the wires or over-tightening of the wires during the installation stage, has created further problems. Because of these concerns, aluminum wiring is now banned from use in branch circuit wiring. Insurance companies are wary of homes with aluminum wiring and most companies require a complete electrical safety inspection by a trained and certified electrical contractor before policies are sold or renewed. Electrical modifications are usually needed and in some cases complete rewiring is recommended to reduce the risk of a house fire.

Overheating:

Copper and aluminum contract and expand differently: the overheating of aluminum conductors can occur at receptacles, switches, pigtails and splices, with the result being either electrical failure, or fire.

Creep:

When you subject aluminum conductors to constant stress, the aluminum is inclined to creep away from the stressed area. As the temperature increases so too does the rate of creep, and this creep will continue until the stress is the same as the ultimate strength of the aluminum itself. So, if you have an aluminum conductor wrapped around the screw terminal of a receptacle or switch, the aluminum will tend to creep away from the screw, thus creating a high resistance termination.

Oxidation:

Aluminum oxide is the fine film that begins to form on the aluminum’s surface within a few short seconds from the bare metal being exposed to the air. Different to copper oxides (which are conductive) aluminum oxides are not conductive and have high dialectic strength. A good aluminum termination means that these oxides are removed during the termination process, thus assisting in preventing the formation of new oxides.

.

Thermal Expansion:

Copper, aluminum, and steel all have different coefficients – meaning that they expand at different rates at different temperatures. When an aluminum-to-aluminum or copper-to-aluminum splice is created in a twist-on wire nut and heated, the aluminum expands more than the steel or copper. Then, the aluminum shrinks as the joint cools which creates an increase in resistance, caused by a loss in contact pressure of the wire nut.

Galvanic Corrosion:

This occurs when copper and aluminum (or other dissimilar metals) are joined together and an electrical current passes through them. The galvanic corrosion is created by the aluminum and copper having such a large difference between them in galvanic potential. This rate of galvanic corrosion may be reduced or limited by plating either one or both of the two metals with another metal of intermediate potential, like tin.

Difficult to Insure:

If you have a home with aluminum wiring you’ll find it difficult to get an insurance company to cover you. For these kinds of homes insurance companies are increasing their premiums, and/or requesting a very detailed and thorough safety inspection, prior to agreeing to insure aluminum-wired homes.
