The device used for joining cable wires or conducting materials is called a lug. Cable lugs join conducting materials to a conducting tube. Wires are inserted into the barrel of the device and then crimped, welded or screwed so the end can be connected to an electrical source or destination.

These lugs are found on generators, transformers, electrical appliances, boxes and automobiles. A main advantage is efficient performance with low voltage drop and less thermal heat generation, helping avoid conductor burnouts.

Copper lugs are available to Indian, DIN, BS and AS/NZ standards. Crimping lugs and crimp terminals finish conductors so they can be used safely in appliances and switchboards. Dimensions vary based on the appliance and cable size.
