How To Identify Aluminum Wiring


Identifying Aluminum Wiring in Your Home

Virtually all residential aluminum wiring was installed as plastic-sheathed or cloth cable (type NM, often called “Romex”) with no readily discernable distinction from a cable with copper conductors.

If you are unable to identify the type of wire in your home by this method, but you suspect that you have aluminum wire, have a qualified electrician make the determination. If your home has aluminum wiring that has not been remediated, Westridge Electric recommends a permanent repair of the connections, as described on this website.
