Main Causes of Terminal Overheating and Blackening 1. Unqualified Contact & Loose Installation Loose crimping, uneven torque and assembly gaps reduce the effective contact area of terminals. Based on the I²R heating principle, local high resistance generates intense heat, scorching metal surfaces and forming permanent black carbonized marks. Excessive crimping also causes micro-cracks and...
