Bi-metallic lugs are typically meant for one-time use and should not be reused after being removed, particularly in critical electrical setups. The crimping process is the key reason for this: when a bi-metallic lug is crimped onto a cable, the barrel gets tightly compressed around the conductor, forming a solid mechanical and electrical connection. This deformation is permanent, and ... https://www.pioneerpowers.com/bimetallic-lugs-and-connectors.php
