How to implement wiring terminal connections on a number of conversion

Both copper and aluminum are excellent conductors of heat and electricity. Many buildings and homes use copper for regular circuits and aluminum for appliance circuits. Unfortunately, the appliances have copper wiring. Because of the dissimilarity in the expansion and contraction of aluminum and copper, it is difficult to connect them to each other with traditional methods. If the connection is not properly secured, excessive heat will result that could cause a fire hazard.
The COPALUM system. It's a form of pigtailing, but the electrician uses a special machine that applies over 20 tons of force to the crimp. When it's done, it is as safe as you can possibly get with the notoriously unsafe aluminum wiring.
The proper way is to get a licensed electrican with aluminum experience to "pig-tail" all the aluminum wire in the entire house. This way you wind up with only copper wires to work with. I live in an area with a LOT of aluminum wiring and made a nice living for awhile doing pigtail work. You use the anti-oxidant compound and al/cu connectors. But the important part is to make sure that the connection is made correctly--something a lot of inexperienced electricians might mess us--and that the wire is skinned back so that it had not been abraded or oxidized in any way. It costs a few dollars, but unless you are ready to have your house burn down, it is worth it.
