In this study, we investigate the phenomenon where momentarily melted copper is scattered from the power source side to the load side during a short-circuit in electrical wiring, caused by arc sparking at the fault. This results in different short-circuit shapes on the power source side compared to the load side. Additionally, we theoretically analyze physical phenomena such as the Lorentz force acting on the electric wire during a short-circuit. By sharing these experimental and theoretical findings, we aim to better understand the mechanism of short-circuit formation and utilize this knowledge to pinpoint specific ignition points in fire investigation contexts.
