Nice catch Russell…
I am not affiliated with the company for this info!
It has been mentioned in
A national survey conducted by Franklin Research Institute for CPSC showed that homes built before 1972, and wired with aluminum, are 55 times more likely to have one or more wire connections at outlets reach "Fire Hazard Conditions"1 than homes wired with copper.
From CPSC website: http://www.cpsc.gov/CPSCPUB/PUBS/516.pdf
Correct and is also stated in Nachi article.
The other sources say over 50 times.
Thanks for all the good information!!
Do you think think applies to Canada, How do you write up Aluminum wire when you find it … Roy
Thanks Joseph - But this thread is a good in in that when something meets the eye, it may appear to be one thing, but a few extra seconds can undercover another…one of the reasons I love this profession…
Standard statement on Home Gauge along with a caution as to Insurance.
Aluminum wire is installed on 120 VAC branch electrical circuits in the subject house. These single strand, branch circuit aluminum wires were used widely in houses during the mid 1960s and 1970s. According to the U.S. Consumer Product Safety Commission, problems due to expansion can cause overheating at connections between the wire and devices (switches and outlets) or at splices, which has resulted in fires. For further information on aluminum wiring contact the U.S. Consumer Product Safety Commission via the Internet at [size=2]http://www.cpsc.gov/[/size]](http://www.cpsc.gov/) . It is recommended that the electrical system be evaluated by a licensed electrical contractor.
I see most of what you post is American .
Like Stablok is OK in Canada but Not USA .
I do not think ESA says much about Aluminum wire .
The same with TSSA does not say Much about inside oil tanks .
It Is the insurance companies who see to be the ones concerned ,
In Brighton No insurance companies will give insurance with Alum Wire 35 miles away 70% of the homes in one section All have Aluminum wires and no problem getting insurance .
Strange Business we are in… Roy
Agreed!
Reporting the presence of AL conductors is entirely different than making an issue of the usage of a substance that is not even required.
BTW, not everyone here is an HI. Some are licensed professionals in other trades.
And this has little to nothing to do with the use or non-use of an anti-oxidant compound on the wire.
Loose connections with any conductor material can reach hazardous temperatures. The problem is the connections, not the conductor material. The AL is not failing between the connections.
The same can be said for the metallic sheath of a cable that is not grounded.
Like you I thought that this was about the anti-ox on the conductors.
That what is started at but it Branched of and many have learned much about many things .
At least it has stayed on electrical mostly .
We love to hear from others and do appreciate the help they Give . Thanks … Roy
Indecently anti ox ( no Corode ) is required in Canada Not sure about USA
Exactly…
From someone that taught me many years ago…
