Aluminum Wiring in Residential Properties: Hazards & Remedies

Is Your Washington Home’s Aluminum Wiring Safe?

Attention Washington homeowners with houses built between 1965 and 1973: This information addresses the potential fire risk associated with solid-core aluminum wiring used in homes constructed during that period.

Key Points:

  • Solid-core aluminum wiring can loosen over time, increasing fire risk. Multi-strand aluminum wiring is not a safety concern.
  • Consult a qualified electrician to assess your specific wiring and recommend appropriate actions.
  • Do not attempt electrical work yourself. It can be dangerous and worsen the problem.

Warning Signs of Potential Issues:

  • Flickering lights
  • Warm switch or outlet plates
  • Burning plastic smell near outlets or switches
  • Unexplained circuit breaker trips
  • Arcing or sparks from outlets or switches

Addressing Aluminum Wiring Risks:

While replacing the entire wiring system is the safest solution, it can be costly. Several repair methods approved by the Consumer Product Safety Commission (CPSC) can improve safety:

  • COPALUM connectors: This method involves permanently joining aluminum wires to copper wires using specialized tools. This is considered the most effective and CPSC-recommended approach.
  • CO/ALR-labeled devices: Replacing existing outlets and switches with specifically designed models compatible with aluminum wiring can address specific connection points.
  • Pigtailing with antioxidant compound: This method involves connecting short sections of copper wire to the aluminum wiring using specific connectors and a special compound.

Remember:

  • Only qualified electricians should perform any work on your home’s electrical system.
  • Early detection and action are crucial to minimizing fire risks associated with aluminum wiring.
