[pdf] MCB busbar overheating is primarily caused by loose connections, undersized components, improper alignment, or oxidation. These create high-resistance points that generate excessive heat through I²R losses, potentially leading to fire hazards and system failure. Immediate fixes include re-torquing. In high-current electrical installations, a melted busbar is rarely the result of a sudden overload. More often, it is the visible consequence of long-term mechanical and thermal stress that the system was never designed to absorb. If I skip the basics, I. However, busbar products often encounter issues such as overheating, corrosion, mechanical wear, and poor electrical connectivity.
