Was your house built back in the 60s or early seventies? If so, your wiring may perhaps be Aluminum. Nevertheless, Aluminum was approved in the National Power Code NEC and Underwriters Laboratories UL rated. Still, there can be safety hazards in the home wiring in metal, especially in older homes. A lot of homes wired over 30 years in the past with Aluminum pose several fire and safety issues that a majority of homeowners may not be aware of. Best way to find the Light Capturing Ribbon.
The condition with the 1350 series metal alloy used in the 1960s and 70s was how the aluminum wire was suitable for power transmission and not intended for branch circuitry. Therefore, straight management of 1350 Aluminum combination wire did not pose a security hazard. However, when properties were being wired with metal on a branch circuitry, each connection made to a passageway box, outlet, and move, posed a safety and flames risk, and many homes feeling stimulated in the 60s and 1970s today still have the original metal wiring.
Aluminum is a less demanding metal, and it expands along with contracts at different charges than the other metals; for instance, copper is used in wiring. Typically the electric current will change the temp of the wire, causing articulations to loosen and bargain the connection.
Once the connection is compromised, some further temperature gains can give to arching or igniting a fire.
The majority of metals, when exposed to the authentic atmosphere, oxidize. For example, when oxidized, copper forms a director; on the other hand, aluminum o2 forms resistance that, at a connection, will cause an additional heat build-up. The oxidation builds up over time and will impact the electrical distribution.
What to look for and what can be done if your aluminum electrical wiring is a probable safety and fire hazard.
Industry-wide, opinions on the methods to replace or restore aluminum wiring are dubious, other than the complete rewiring along with copper wire which can be very costly. Therefore, a second option is the Copalum crimp repair.
The Copalum crimp repair is the best solution to rewiring using copper. However, it is not an easily available solution because the crimping tool can only be rented by licensed electricians extensively trained and certified with the manufacturer in the Copalum method.
Finally, electricians often employ pig-tailing using special angle connectors compatible with attaching Aluminum and copper because materials to repair with this process are readily available. A licensed electrician with specific maintenance experience should only use this process.
Although the Aluminum is available and used today is much less hazardous than 30 years ago, AA-8000 series, UL rated along with NEC approved, most electricians would not run Aluminum in just about any new residential home.
