Our View of Aluminum Wiring Based on our research and inspection experience, the use of aluminum wire should not be a reasonto avoid buying a house. There are, however, some cautions about aluminum wire that should be discussed with potential buyers. Not only do our inspectors fully examine the electrical system, we present this information in a manner that helps clients keep the issue in perspective.

Brief HistoryBuilders began using aluminum wire around 1965, when the price of copper wire skyrocketed. A considerable numberof homes have aluminum wiring -- in fact, in most areas of the United States the use of aluminum wire is still code permitted.

Many studies have shown that electrical problems are more likely to occur with aluminum wire than with copper.However, most concerns are restricted to single strand aluminum wire used in branch circuits not the stranded heaviergauge wire used for service entrance and large appliances. Single stranded wire tends to work loose at the screw terminals causing overheating, malfunctions and occasional fire. Correcting these problems led to changes in installationmethods around 1973.

New TechnologyHomes constructed with aluminum wire since 1973, have "new technology" wiring that comply with electrical codes

requiring UL listed circuit breakers, receptacles, switches, andwire nuts ( i.e., aluminum compatibility labeling: CO-ALR orCO-AL). Installed properly, these devices keep the connectionstight and should greatly reduce any potential problems. If anoutlet or switch ever needs to be replaced, replacementdevices should be labeled "CO-ALR".

Old TechnologyUnless upgraded, homes built between 1965 and 1973, have"old technology" aluminum wiring. There are few documented cases of house fires caused by aluminum wiring -with the majority of problems involving mobile homes andrecreation vehicles. "Old technology" aluminum wiring will

usually perform satisfactory if properly installed. There are no code requirements to make improvements and typicallyinsurance companies will not refuse to cover a home with aluminum wiring. However, homeowners should watch forwarning signs and consider some form of upgrade from an electrical specialist.

Homeowner suggestions include:With every inspection we provide 12 months of our Extended AdviceSM program so your clients always have a directsource for accurate information about their homes. For aluminum wire, we recommend the following:

-- Be aware of warning signs: excessive light dimming, arcing at switches, warm cover-plates at switches or outlets, strange odors, burnt wires or corrosion on electrical connections, or faulty outlets or circuits.

-- Periodically check the connections at outlets and switches to make sure wires are tight and there are no hotspots. Hot or warm outlets and switches indicate a need for repair.

-- If you wish to be proactive or have a concern, upgrade old technology by replacing switches and outlets withthe labeled CO-ALR devices.
