Electrical Safety Alert: The Dangers of Aluminum Wiring in Older Homes

Estimated Read Time: 2 minutes

An Introduction to Hidden Risks

When considering the safety of your family and home, addressing electrical hazards is crucial. One lesser-known danger lurking in many older homes is aluminum wiring. Commonly used between 1965 and 1974 as a substitute for copper, aluminum wiring poses significant risks if not properly managed. Knowing these dangers can prevent fires and ensure your household's safety.

Why Aluminum Wiring Was Once Popular

Aluminum was once a preferred material due to its low cost and availability. It was commonly used in homes amid a copper shortage. Unfortunately, many homeowners were unaware of its potential risks, which became apparent over time.

The Dangers of Aluminum Wiring

  • Overheating and Fire Risks: Unlike copper, aluminum is soft and easily expands. This expansion and contraction can cause the wire to become loose and overheat, potentially sparking electrical fires[0].
  • Incompatibility with Modern Fixtures: Aluminum is incompatible with most modern electrical fixtures. Connections can become loose over time, leading to arcing and, ultimately, fires.
  • Corrosion Issues: Aluminum interacts chemically with many metals used in terminals, increasing the risk of corrosion and overheating[0].

Signs Your Home May Have Aluminum Wiring

If your home was built between 1965 and 1974, there is a chance aluminum wiring is present. Look for the following indicators:

  • Discoloration or char marks on outlets and switches.
  • Frequent electrical issues, such as tripping circuit breakers or flickering lights.
  • The smell of burning plastic or singed wiring.
