What’s the big deal?
Bottom line is that insurance companies are terrified of it even, though we still use it today. Most hot tubes are aluminum wire and cities still use it to run to the house. The problem is the connection points…and NO HGTV it is not evaporating…pffft. Heat=expansion so if the connections are not rated for aluminum these expansion moments can, over time, loosen the connections. Loose connections mean electrical arcing. Electrical arcing=fire can start.
What if I have it?
TELL your insurance company. I will observe for any evidence of overheating but if not I just note it in the report for your reference but your insurance company may want you to have it inspected by an electrician.
Do I have to replace it?
NO. Electricians will splice the ends with a special connector to connect to copper then reattach at the outlet. Dont believe the shows that say it needs to be replaced because it does not.
Below is more information from multiple sources
- inherent weaknesses were discovered in the metal that lead to its disuse as a branch(meaning from the panel to the plug) wiring material.
- Aluminum will become defective faster than copper due to certain qualities inherent in the metal.
- Neglected connections in outlets, switches and light fixtures containing aluminum wiring become increasingly dangerous over time.
- Poor connections cause wiring to overheat, creating a potential fire hazard.
- On April, 28, 1974, two people were killed in a house fire in Hampton Bays, New York. Fire officials determined that the fire was caused by a faulty aluminum wire connection at an outlet.
- According to the Consumer Product Safety Commission (CPSC), “Homes wired with aluminum wire manufactured before 1972 [‘old technology’ aluminum wire] are 55 times more likely to have one or more connections reach “Fire Hazard Conditions” than is a home wired with copper.”
