What Are Arc Faults?

Arc faults are a type of electrical malfunction caused by high-power discharge of electricity between two or more conductive paths. Arc faults occur when electrical current “jumps” across a gap between conductors. This can happen due to a variety of reasons; such as damaged wires, loose connections, or the presence of conductive materials (like nails or screws), or even wear and tear over time. Arc faults generate significant heat, leading to fire hazards in homes and other structures. To mitigate these risks, arc fault circuit interrupters (AFCIs) are used in electrical systems to detect and interrupt arc faults, significantly reducing the risk of electrical fires. Regular inspection of electrical systems, proper installation and maintenance of electrical wiring, and avoid damage to wires can also help prevent arc faults.
