What is Arc Fault in Solar Systems and how to deal with it

An arc fault in a solar system occurs when an electrical current jumps across a gap between two conductive surfaces, creating a brief but intense burst of heat and light. This can happen when there is damage or wear to electrical wiring, connectors, or other components in a solar PV system, creating a pathway for the current to arc.Arc faults can be dangerous
