Manufactured in O'Fallon, Missouri by King Innovation, AlumiConn® is a lug style wire connector designed as a permanent repair for aluminum wiring in residential and commercial buildings. AlumiConn is UL Listed to meet US & Canadian specifications, declared dependable & economical by independent tests, and approved by the Consumer Product Safety Commission (CPSC). An affordable option for aluminum wiring repair, AlumiConn is often preferred to other methods by Electricians and homeowners. 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.
