This guide explains the four main cable lug types — copper lugs, aluminium lugs, friction-welded bimetallic lugs and pre-insulated lugs — and shows how to match each one to the conductor and terminal materials, covering cable sizes from 10 mm² to 630 mm². You will learn the material grades that matter (T2/T3 copper, 1070 aluminium), what IEC 61238-1 type testing proves, and the three selection mistakes that lead to overheating and galvanic corrosion, so engineers and buyers can specify the right cable lug the first time.
