Are Ideal 65 wirenuts an acceptable solution to repairing aluminum wiring in homes. I am also a master electrician, but have not had to deal too much with this. I became aware of two other solutions, COPALUM crimp style connectors, and Alumiconn screw type. It seems the consensus is COPALUM and I wonder if there is an underlying motivation to all the things I'm reading
Welcome. My name is XXXXX XXXXX would be glad to assist.I would only use the Alumiconn or the Copalum connectors to make changes to the aluminum wiring.They all to get a copper conductor to attach to tall the devices and keep the aluminum away from the copper.When you use something such as Ideal 65 wire nuts, you are actually joining the 2 dissimilar metals and that is where the trouble starts.The latest publication from the U S Consumers Product Safety Commission says onlyCOPALUM or Alumiconn to be used. CLICK HERE to read the Commission statement:Briefing package dated March 15,2011I wired many homes in the late 70's with the aluminum.What we know now should have been known then but unfortunately, the copper shortage was killing the home builders, so they devised a quick alternative that was used in the 60's also.
Just click reply for any other information.
Additionally, what is the material being used in each of the "accepted" methods? Wouldn't there remain a possibility of electrolysis?
Your answer of "Click Here to read the publication" is disappointing. I already stated that I had read it. It doesn't answer my question.
Wirenuts aren't designed to be a mechanical connection. I always twist the wires together before I use them. If the wires are twisted properly, would the 65's be acceptable? In your opinion?
It is nice that you twist the wires before the wirenut, as on so many service calls, the wires were only twisted by the wire nut and slowly heat and cool to become loose.
There is NO corrosion with the 2 approved methods.The CPSC helps to keep us safe and only approve the 2 mentioned as a viable solution.Using a wire nut will corrode and deteriorate, they just wrap each other together.The crimp connectors crimp each one separately so there is not the problem as a wire nut.I would not recommend nor use a 65 wire nut on aluminum.
