Wrong crimping tool or die use when putting in copper cable lugs has severe and potentially hazardous effects on electrical and mechanical performance: Higher Contact Resistance: A wrong tool or die may not deliver the correct compression, resulting in inadequate deformation of the conductor and lug. This means higher joint resistance, leading t

Stranding class of the conductor is important in  copper cable lug selection because it influences directly the fit, electrical performance, and mechanical reliability of the connection. Here's why: Physical Fitness: Fine-stranded conductors like those of Class 5 and Class 6 according to DIN 57295/EN 60228 contain more overall diameter than fin
