Aluminum vs Copper Wiring: Root Electric Can Evaluate Aluminum Wiring in Homes to Determine Fire Hazards and Fix Them
A large number of homes built between the mid 1960’s and mid 1970’s were built using aluminum wiring instead of the more expensive copper wiring. Aluminum wiring in homes during that era was commonly used as a cost-saving measure. Years down the road, however, unanticipated fire hazards arose from the oxidation and deterioration caused at the points where aluminum wiring was connected at outlets, light fixtures and splices. This can cause overheating and arching that won’t trip a circuit breaker, but can cause a fire. The Consumer Product Safety Commission estimates that about 2 million homes, a number of which are in Northern Virginia, still struggle with the aluminum wiring conundrum.
Aluminum vs Copper Wiring: What You Need to Know
The first thing every homeowner should know is that aluminum wiring, in and of itself, is not always a fire hazard. In fact, there are even new homes built today that include aluminum wiring elements. The most common modern aluminum wiring in homes includes the main service cable, as well as feeds for heavy-duty appliances such as en electric range or heat pump. These are generally safe applications that should cause no concern as long as they were properly installed.
Fire hazards with aluminum wiring in homes, particularly ones built from the mid 1960’s to the mid 1970’s, come from age-deteriorating branch circuits: splices and connections made at outlets and light fixtures. Usually, electrical fires start at these locations because the switch or outlet installed was not designed to be used with aluminum wiring. Fires can also start if there was no anti-oxidation compound applied to the wires in the first place. If oxidation is not prevented, that is when dangerous overheating and arcing occurs.
Only an experienced electrician can determine the level of danger a home faces, and then fix those problems. There are several aluminum vs copper wiring solutions available to homeowners today, but because each house is unique, a complete evaluation is necessary before we can determine what options will reduce a home’s fire risk. Completely rewiring the home from aluminum to copper is one option, but a very expensive one that only makes sense if you are already in the process of completely remodeling or doing deep renovations. Retrofitting and repairing the dangerous connections is also an option for some homes.
