Re: [DIY] Re: Now about space heaters

 

There are numerous accounts available on the web concerning the fire hazards associated with residential aluminum wiring.  I am posting but only the first portion of one of these that was originally printed in the New York Times.  The proble with aluminum is that it eventually oxidizes which causes heat to begin which increases the oxidization further increasing the associated heat buildup until a fire is the result.  Aluminum wiring is no longer approved in most areas for any use other than drops and open air feeds.

ACCORDING to the Consumer Product Safety Commission, an estimated two million homes in the United States were built or renovated using electrical circuits with aluminum wiring. And, according to the commission and specialists in the field, unless certain safety procedures are undertaken, every outlet, light switch and junction box connected to such circuits is a fire waiting to happen.

Aluminum wire is safe. Aluminum conducts electricity fine. A lot of
service lines are aluminum wire. The problem comes in when people splice
aluminum and copper together or use devices that are not for aluminum
wire. The dissimilar metals react and the oxidation causes increased
resistance which may result in over heating. There are lots of
conventional houses wired with aluminum.
