Three ports allow conductors to remain separate, permitting the lug to provide lower resistance, therefore lower temperature and to provide longer-term reliability.
Recently approved by the Consumer Products Safety Commission (CPSC), the AlumiConn® Aluminum to Copper Lug is one of the most popular solutions for aluminum wiring repair in residential and commercial buildings.
AlumiConn is a lug style wire connector designed as a permanent repair for aluminum wiring in homes and commercial buildings. As an aluminum wire is inserted into the AlumiConn lug, it is coated with a thin layer of silicone grease to provide resistance from oxidation. When the set screw is tightened down it compresses the surface of the wire, which breaks up any surface oxides and provides a secure mechanical connection. In addition, the AlumiConn connector itself is constructed using tin plated aluminum, which relieves any issues related to dissimilar metals. AlumiConn is UL Listed to meet US and Canadian specifications, declared dependable and economical by independent tests, and now approved by the CPSC.
