Re: Aluminum Wiring Help
If you remove the outlet from the electrical box be careful to re-tighten the screws holding the aluminum conductors. The problem with aluminum wire is that aluminum has cold flow characteristics. That means that if you tighten a connection today the connection can loosen up all by itself as the aluminum flows away from the terminal. That means that the resistance of the connection slowly increases. I learned about the reason for the aluminum problem, when I helped a friend determine why an outlet he had a toaster plugged into, suddenly burst into flame. The outlet was connected with aluminum wire.
Modern terminals designed to terminate aluminum conductors compress the conductor from all directions and have a knurled surface to increase the surface area and make the connection more resistant to cold flow. On large gauge conductors it is important to apply an anti oxidizing compound to the conductor before inserting it into the terminal.
