In recent years there has been an increase in the concern over the safety of aluminum wiring; in particular, purchasers or owners of homes built from the mid 1960’s to the late 1970’s. When aluminum branch wiring was introduced in the 1960’s, the wiring material changed but the same copper devices were used.
When electricity flows through either metal, it causes it to expand and contract. Aluminum and copper have different expansion properties so when the two different metals are connected, the differences in the expansion properties can cause the connection to become loose. Loose connections can result in sparking, arcing oxidation and heat build-up, all of which are safety hazards.
How can you tell if you have aluminum wiring?
The only way to know if you have aluminum wiring is to inspect the electrical branch wiring system. If you’re not comfortable around electricity and wiring then call in a pro! It’s a small investment to have a licensed professional do the work for you.
The Electrical Safety Authority (ESA) recommends that the home owner hire an authorized electrical contractor that is knowledgeable in the approved methods for working with, and repairing aluminum wiring.
You have a couple of options:
