Aluminium lugs are the most common and most used type of lugs. Aluminium lugs are much cheaper than copper ones. They even go back to the early days of the 1960s. Back then, aluminium was the most used metal and we’re being used generously in almost every wiring system. Since all the electric wires at home were made up of aluminium metal, it makes sense to use the aluminium lugs at the connection junction. Aluminium expands and contracts as it heats and cools quickly. Because of this aluminium wiring and lugs can losses quickly as compared to copper lugs. The one disadvantage of using aluminium lugs is that there are many termination failures. Aluminium connection junctions fails frequently and due to this electrical fires can happen frequently. Aluminium lugs also have some major safety issues. After all these issues it was decided that aluminium lugs are not a good fit for electrical working. Here’s where copper comes to the picture as a more effective and easy replacement.
