According to the U.S. Consumer Oroducts Safety Commission (CPSC), Tyco Electronics' COPALUM crimp connector repair system, which uses a cold weld to attach a copper wire to the old aluminum wires, is the only system that has been recognized to provide a complete and permanent repair.
To insure that repairs are properly made, the system's connector repair materials and power crimpimg tools are available only to electricians who receive training from the manufacturer.
Without the Tyco system, the only way to safely upgrade aluminum wiring systems is to install new copper circuits.
