Safety, Efficient and Economy, Create a Better Life. Aluminum to Copper Lug Depending on the size and material of the conductor used, tighten the set screws to the torque indicated below: #12 Solid Aluminum 10 in-lb #10 Solid Aluminum 15 in-lb All solid and stranded copper conductors 15 in-lb Aluminum to Copper Aluminum to Aluminum Copper to Copper Read more Excellent Performance Casing The plastic shell has good insulation and resistance to organic solvent corrosion. The operating temperature range is -25 ~ 135 ℃. Convenient Design The lug is tinned, and the copper wire can be connected to the lug directly without tinning when repairing the aluminum wire. Better Security Measure Port filled corrosion inhibitor provides oxidation resistance and good sealing for further safety. Read more
Aluminum to copper wire connectors are designed as safety mechanical lugs for aluminum to copper connection, eliminating the risk of electrochemical reaction caused by direct connection between copper wire and aluminum wire. This is a very cost-effective way to repair aluminum wiring in buildings currently.
The aluminum to copper lug can withstand voltages up to 300V and is suitable for #12 to #10 solid aluminum wire and #18 to #10 solid or stranded copper wire. It is mainly used for the connection of copper wire and aluminum wire, and can also be used for the connection of aluminum to aluminum and copper to copper wire.
The nickel-plated compression screws of copper aluminum wire connectors can break down the oxide layer on the wire surface and provide a secure mechanical connection. The port wiring method eliminates the mixing of conductors, so as to prevent electrical fire caused by overheating of aluminum wire, which is a safe and permanent aluminum wire repair solution.
The lugs of aluminum copper wire connectors are tinned to provide lower resistance and lower temperature. The corrosion inhibitor filled in the port can provide oxidation resistance and sealing, preventing the aluminum wire from corroding which causing poor contact and increasing the temperature of the contact site.
Installation of aluminum to copper lug is so simple that anyone with general electrical knowledge can install it. Only one wire is connected to each port and the fixing screws are tightened according to the specified torque depending on the size and material of the conductor. Close the lid after installation and confirm that the latch is fastened.
If you have ALUMINUM wiring in your house, you have an aluminum to copper transition somewhere!! Just connecting the wires together with a wire nut is NOT safe since these two metals expand and contract differently when heated over time. This will then cause a micro-separation between the two metals which causes and arc which can cause a fire. We found out the hard way that we had aluminum to copper transitions incorrectly done in our house. THESE ARE SIMPLY THE BEST CONNECTORS to solve this problem.Perfect for copper to aluminum connectionsGreat product. We changed all the aluminium terminations to copper using these.My house was built in '72 and like many of that era has aluminum wiring. I was doing some electricalupgrades and an electrician acquaintance told me about Alumi Conn aluminum to copper connectors.He said that is the best way to eliminate the issue of oxidation and difference in coefficient of thermal expansion between Al and Cu. They are easy to use and provide ease of mind about a potential electrical fire.Great to connect aluminum wires with copper safely. You Cannot used standard wire nuts when connecting copper with aluminum. These allow them to be connected safely and to code reducing the chance of your connection coming loose if it ever get hot. They need to offer these in a little bit larger wire size because aluminum wire is always bigger than copper to carry the same amperage load.
