Aluminum wire was commonly used 1965-1975. It was a more cost efficient type of wire then copper at this time. It was found that the conductivity of aluminum wire was equal to copper at a larger gauge. The issue with aluminum wire is that it is extremely soft and creates weak spots if handled the wrong way. The other concern with aluminum wire is that the devices that were used at the time of installation were not rated for aluminum wiring. Due to the far greater expansion and contraction of aluminum wire in comparison to copper, the electrical devices used were designed for copper wire only. The deficiency found with this method was that over time the aluminum wire would loosen the connection point to these devices therefor causing the chance of an electrical fire.
There are a couple ways that you can correct aluminum wiring. One is to change all your devices in your home to aluminum rated devices. Another is to "pig tail" your existing devices. The best option is to have Inline Electric do a free estimate to retrofit your home. If you have a home that was built in this era it is our recommendation that you call us for a home inspection.
