Arc fault
What is an arc fault and what causes it? An internal arc is a high-energy discharge of electricity between two or more conductors. An arc fault occurs when loose or corroded connections make intermittent contact and spark or spark between connections. This creates heat that breaks down the cable insulation and can cause an electrical fire.
