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 Due to the sudden rise in the price of copper materials from the mid-1960s to the 1970s, aluminum wires are widely used in the United States. Therefore, the houses built in that period are likely to be connected by aluminum wire layout. Aluminum wire is less conductive than copper wire, and as the number of household appliances increases, aluminum wire can become overwhelmed, multiplying the potential for overheating, and ultimately prone to electrical fires. While whole house rewiring would be a complete and permanent solution, it's not the most practical solution due to the expense. Therefore, most people will partially change the wiring according to their needs, and this will involve the problem of copper and aluminum wiring. As we all know, if copper wire and aluminum wire are connected directly, electrochemical corrosion will occur, which will cause poor contact between copper and aluminum and increase the contact resistance. When a current passes through, the temperature of the joint will rise, and the temperature rise will accelerate the corrosion of the joint and increase the contact resistance. Such a vicious cycle, until burned, and even cause a fire. To solve this problem, we provide copper to aluminum connector. This is a safety mechanical lug specially designed for connecting aluminum to copper, avoiding the direct mixing of different conductors. The tinned lug reduces the generated resistance, and the nickel plated compression screw can break up the oxide on the surface of the metal wire and provide secure mechanical connection. The port is filled with corrosion inhibitor to further prevent the conductor from being corroded and provide sealing, which can realize more lasting connection and provide safer and long-term reliability.
