How to Identify Aluminum Wiring

Aluminum wiring was used in residential electrical wiring in the 1960s and 1970s due to a copper shortage. Approximately 1.5 million homes built in the United States during that time period used aluminum wiring. However, this type of wiring was phased out by the mid-1970s because it presented several dangers, including an increased fire risk and corrosion issues.

In this article, Mr. Electric explains how to identify aluminum wiring and why we are the team you can count on for electrical wiring.

How to Identify Aluminum Wiring?

  • Check the Color of Exposed Wiring: The simplest way to figure out if you have aluminum wiring is to check the color of your wiring. Aluminum wiring has a natural silver-ish, shiny appearance, similar to steel. It’s quite distinct from copper wiring, which is more of a reddish-brown color.
  • Wiring Insulation Labels: Another common way to know you have aluminum wiring is to check the plastic wire covering. Look for the printed or embossed markings on the plastic wire covering. The plastic wire jacket has the words AL, ALUM, AL ACM, ALUM ACM, or ALUMINUM printed or embossed on it. In unfinished areas of your home, like the basement, attic, or crawl space, you might see exposed wires running between electrical panels, outlets, and switches.
  • Your Home Was Built During The 1960s And 1970s: If your home was built during the 1960s and 1970s, there’s a good chance you have aluminum wiring. This period coincided with a rise in copper prices and a surge in home construction. Aluminum offered a cheaper and lighter alternative to copper wiring at the time. There are several ways to find out when your house was built.  You can check your title deed or contact official sources, such as the assessor’s office or the building department. If your home was built during this period, call a professional electrical repair service to perform an inspection and determine whether you have aluminum wiring.
  • Call A Nearby Electrician: If you don’t want to go through the hassles of checking your wiring or digging up property records, simply pick up your phone and call professional electricians. Qualified electricians have the know-how and experience to identify different types of electrical wiring. They can also inspect your home’s wiring to identify any issues like faulty connections, overloaded circuits, or outdated components. If you’re searching for an electrical repair service to inspect your electrical wiring, look no further than Mr. Electric.
